What is a 446 Stainless Steel Bar? 

446 Stainless Steel is a standard grade of stainless steel used in the manufacturing industry. It has a high level of chromium and nickel, making it resistant to corrosion.

It is typically used for industrial purposes and precision grinding because it has better corrosion resistance than other grades. This grade can also be found in household items like cookware and flatware.

This stainless steel bar stock belongs to the 400 Series, which is ferritic stainless steel with more than 23 percent chromium concentration.

Its high chromium concentration permits this type of stainless steel bar stock to have outstanding corrosion resistance and is acclaimed to be the best among the ferritic stainless steel grades.

It is non-hardenable but has outstanding corrosion resistance at significantly higher temperatures and possesses good mechanical properties. This grade has poor high chromium content. Because of its superior oxidation resistance at high temperatures, it is widely used as furnace parts and boiler baffles.


446 stainless steel bar is an essential metal in the construction industry used in various ways. 446 steel is a type of stainless steel bar stock that can be used to substitute other types of round-ground metals. It has been used in construction projects because of its corrosion resistance.

The 446 stainless steel bar has many uses in the construction industry. It is a round ground metal perfect for precision grinding. The 446 Steel is also available in different sizes and grades to best suit your needs.

Moreover, as mentioned, it belongs to the ferritic grade family of steels, a 446 stainless steel bar, which cannot be hardened by heat treatment. However, it is known to be magnetic, has good ductility, and exhibits strong corrosion resistance and oxidation resistance.

This stainless steel grade is magnetic, can tolerate higher temperatures without becoming brittle, and has excellent mechanical qualities. However, 446 stainless steel bar stock has weak ductility due to its high chromium concentration.

With the outstanding machinability of 446 stainless steel bar stock, a round bar or rod can be easily produced if the speeds are slow, the tooling surfaces are sharp, the mounts are rigid, and the feeds are positive.

Industries involved in the fabrication of furnace components, kiln linings, and annealing boxes require the 446 Stainless Steel bar stock due to its high corrosion resistance. Aside from being suitable for precision grinding, it is renowned for its excellent resistance against oxidation in air and oil-ash corrosion, as well as resistance against copper, lead, and tin. To give you a better view, here are the top two general uses of stainless steel in the construction industry:

  1. Bridges: Duplex stainless steel, a modern family of stainless steel alloys, is increasingly used in bridges and other engineering constructions as these steels are often twice as strong as ferritic alloys. Less material is needed because of its improved strength, making it more cost and weight-efficient.

  2. Civil Engineering: Stainless steel possesses similar desirable features to standard steel but avoids problems like corrosion. As a result, stainless steel that undergoes precision grinding has become increasingly popular as a building material. Drainage and water systems, roofing, and wall supports are also common uses for stainless steel. Without stainless steel in construction, we would likely see a rise in building prices as other substitutes are more expensive. Additionally, buildings would not be as aesthetically pleasing and would be less resistant to corrosion.

The 446 round ground metal is a type of stainless steel resistant to corrosion. It has high strength and hardness, as well as a low carbon content. These are all qualities that make it very important in the construction industry.

Hence, with that said, one can easily find 446 stainless steel bar stock suppliers capable of providing quality stocks. You can even find the best suppliers that offer quality precision grinding and machining services.


446 stainless steel is a type of stainless steel used in the manufacturing of metal bars and other metal products. It has high levels of chromium and nickel, which make it resistant to corrosion.

Its components

This 446 stainless steel bar is a metal that has high strength. These round-ground metals are made of a combination of chromium and nickel. Chromium and nickel are the components that give this metal its high strength, making it perfect for use in various applications.

The 446 stainless steel bar has many advantages over other grades of stainless steel. One advantage is that it can be easily fabricated by cold working, which means it can be cut to size without heating the metal. This makes the metal more economical than others and also reduces the risk of thermal stress cracking.

Its amazing abilities

The strength of the 446 stainless steel bar is high, which makes it ideal for use in the construction industry. The round ground surface also makes it easier to manufacture metal products with a higher level of precision.

It is a form of stainless steel that is resistant to corrosion. Among other things, this metal has several advantages. Corrosion is not an issue: Stainless steel’s inability to rust or corrode when exposed to water or other liquids is one of its most valuable features. The presence of chromium prevents oxidation, making this metal impervious to the effects of the elements.

Also, the strength of this 446 stainless steel bar is one of the best in the world. It has a yield strength of 50,000 psi and ultimate tensile strength of 100,000 psi. There is no doubt that the 446 stainless steel bar is an excellent metal for structural applications. It has a high yield strength and maximum tensile strength.


It is essential to know how to use the 446 stainless steel bar in construction projects properly. The 446 stainless steel bar is a round ground metal that can be used for various purposes. It is often used as a structural support, which can be straightened and then welded into place.

446 Stainless round ground metals are a type of steel with a high degree of resistance to corrosion and oxidation. It is used in construction projects and other industrial applications.

It is important to note that the 446 stainless steel bar stock must be straightened before it can be used for construction purposes. This can be done by using a machine called a “straightener” or by manually operating a series of rolls and presses.

The 446 stainless steel bar stock can also be made round by precision grinding it on an abrasive surface, which will remove any imperfections on the surface of the metal. It is important to handle this type of material correctly. So, learn the best way to process 446 stainless steel bars below:


These round-ground metals are heat-sensitive. Steel 1.4762 should be welded with the lowest practical heat input by using a narrow electrode diameter and stringer bead welding. For wall thicknesses under 3mm, there is no need to preheat 1.4762.

For thicker construction components (> 3mm), preheating and temperatures exceeding 200-300°C should be avoided. 1.4762 can be treated using comparable or higher alloyed filler metals. A ferritic top layer should be applied on the media side (Thermanit L 1.4820).

Cold Forming

When cold forming 1.4762, some precautionary measures should be taken. Sheets up to 3mm thick can be cold bent if necessary; preheating at 200-300°C should be done. Products with thicknesses > 3mm must be heated up to 600-800°C. Considering machinability, 1.4762 may be compared to low-carbon steel.


While heating 1.4762 above around 950°C, embrittlement by grain development occurs, which cannot be removed anymore. Further embrittlement occurs in the temperature range between 400 and 550°C. Extended exposure within this temperature range should be avoided. This loss of ductility can be rectified by briefly heating up to 700 to 800°C.

Note: Ensure specific temperature requirements: Within a temperature range of 600 to 900°C, these round ground metals will tend sigma-phase embrittlement. The ductile values are considerably reduced after extended exposure within this temperature range. The 446 stainless steel bar should not be used within this temperature range if mechanical tension is present.


Generally, stainless steel round ground metals have been utilized in the building and construction industry since they were first created over a hundred years ago. Stainless steel goods are beautiful, corrosion-resistant, require minimal maintenance, and have good strength, toughness, and fatigue qualities.

Stainless steels are easy to produce and are recyclable at the end of their life. They are the material of choice for applications placed in challenging conditions, including industrial processing facilities, buildings, and structures in coastal locations. The high ductility of stainless steel that undergoes precision grinding is a valuable attribute.

Therefore, the construction industry uses this material to create buildings, bridges, and other structures. The use of round-ground metals has caused a boom in the industry.
