Uses of 17-4 PH Stainless Steel

17-4 PH Stainless Steel BarsThe study of metals led to numerous products that have become an integral part of everyday lives. Metals have been employed in various products, from everyday cooking utensils to spacecraft. Metals have their unique qualities and properties. Several components necessitate the use of elements with specific attributes. Whenever metal isn’t suitable for a given application, it’s mixed with other elements to form an alloy.

Stainless steel is a standard alloy used to make a variety of products. Heat treatments are used for strengthening stainless steel, resulting in precipitation hardening of the material. 17-4 PH stainless steel is among the most commonly used forms of PH stainless steel.

17-4 PH Stainless Steel Bars

17-4 ph steel is a precipitation-hardening martensitic stainless steel containing nickel, copper, and chromium. 17-4 stainless steel provides a unique combination of strong corrosion resistance, toughness, and high strength in welds and base metals.

This alloy has outstanding corrosion resistance similar to 304-grade stainless steel for various food, paper, and chemical industries, and it resists corrosive effects better than many other stainless steels. Certain qualities enable manufacturers to improve product reliability while simplifying manufacturing and, in many cases, lowering costs.

It can maintain high strength up to 600°F. At higher temperatures, 17-4ph offers excellent resistance against stress corrosion cracking (SCC). 17-4 ph has a particular combination of characteristics that makes it an excellent option for various design and manufacturing issues.

17-4 PH stainless steel bars are supplied in various forms at Advance Grinding.

Features of 17-4 PH Stainless Steel

17-4 PH is better known as grade 630 stainless steel and is frequently used as the precipitation-hardening metal. It takes heat treatment to generate a broad range of incredibly high strength qualities compared with similar PH alloys. It has more ferrite than typical PH grades, making it significantly more magnetic. Heat treatments can be applied prior to cold working for increasing formability. 17-4 PH has good corrosion resistance plus hardness in welds and base metals. It’s ideal for uses that demand simple construction, additional strength, and hardness for increased reliability.

Advance Grinding is a supplier of 17-4 stainless steel bar and 17-4 ph stainless steel screws, in addition to supplying 17-4 PH round bar. 17-4 Ph stainless steel is used in aerospace, pulp & paper, food processing, nuclear industries.

Applications of 17-4 PH Stainless Steel

17-4 PH Stainless Steel Bars

17-4 PH stainless steel has several applications in paper, aerospace, food processing, and petrochemical industries. It’s useful for a variety of general metalworking applications.

Aerospace Industry

17-4 ph is used in the aerospace industry because it has excellent resistance to corrosion and great tensile strength. Such advantages are critical since aeroplane components and parts, as well as various aerospace equipment, must operate in a variety of environments and temperatures, making corrosion resistance with high strength essential.

Pulp & Paper Industry

The alloy’s adaptability makes it useful in industries such as paper and pulp. This industry requires stainless steel bar stock type that is both corrosion resistant and sturdy enough to function in extreme conditions. As a result, 17-4 stainless steel bar is an excellent option for the pulp and paper industries. Because the paper and pulp industries interact with water and chemicals, stainless steel bar stock with high corrosion resistance is required. It also saves money as the equipment is not prone to rust and breakage.

Nuclear Industry

Every nuclear sector is required to utilize stainless steel. Nuclear power plants must deal with water, fuel, and chemicals to create electricity. As a result, they must employ a 17-4 stainless steel bar with strong corrosion resistance and outstanding toughness. Stainless steel grade 17-4 ph is commonly used to make dry casks.

The dry cask’s construction uses a 17-4 ph round bar and 17-4 ph stainless steel screws, guaranteeing that the spent nuclear fuel is kept

Food Processing Industry

17-4 ph stainless steel is always the first preference for every food processing industry for fabricating equipment since it has good resistance to corrosion. The alloy’s surface finish and high content of chromium make it less vulnerable to corrosion, easily cleaned, and highly durable, which is essential in the food processing industry.

Motor & Pump Shafts

17-4 ph stainless steel is an ideal choice for manufacturing various components for pumps and motors as it has high strength and toughness, as well as excellent resistance to corrosion.

Oil & Gas Industry

It is employed in the gas and oil sector for two significant reasons. Firstly, oil is often found at enormous depths under sea level. High pressure is linked with such depths. Because of its high strength, 17-4 ph round bar is an excellent choice of piping at these depths. Secondly, the Grade 17-4 PH is highly resistant to corrosion onshore and offshore.

It is the best material for drilling rigs and oil pipes due to its excellent resistance to corrosion attack by hydrogen sulfide, carbon dioxide, and poor pH levels during oil prospecting settings.


It is undeniable that 17-4 PH stainless steel grade is the most commonly used PH stainless steel. 17-4 ph grade possesses a perfect mix of resistance to corrosion, excellent tensile strength, plus good mechanical qualities at extreme temperatures. These properties make it a highly versatile alloy that may be used in various applications. It is the best and most widely used stainless steel bar stock due to its exceptional qualities and low cost.

Advance Grinding is the most dependable producer of stainless steel bar stock, with years of expertise in producing stainless steel bar stock in various forms and grades for a variety of industrial uses. 17-4 ph stainless steel is available in 17-4 ph stainless steel screws, 17-4 ph round bar, and 17-4 stainless steel bar.
