Stainless Steel Grades

Best Stainless steel grades

It grades differ in their properties and elemental compound composition, enabling them to be used in multiple applications.

Stainless steels are always sought by industry engineers and designers, as well as manufacturers due to their known exceptional properties. There are a variation of many steel grades, each designated for specific applications depending on their featured properties and strength.

Like all other metals and grades, stainless steel grades are also evaluated and tested with their featured properties and strength for the proper selection and placement of their designated applications.

As they differ in the mechanical properties they exhibit, stainless steels also differ in the manner of how they are machined and forged. Particular metalworking processes are appropriate for each exact type of steel grade, and a rigorous and thorough grade selection is necessary.

Below is a list of the grades of Stainless Steel that Advance Grinding offers.

303AusteniticCold only/ non-magnetica good machinable austenitic with its additional sulphur content. less corrosion resistant than 303 and 316nuts, bolts, gears, etc.
304AusteniticCold only/ non-magneticmore suitable for complex forms than 301kitchen appliances & sinks, truck trailers, architectural paneling, food processing equipment – milk brewing, wine making, beer brewing
316AusteniticCold only/ non-magneticmost expensive austenitic, has better corrosion resistance with its additional molybdenum contentpharmaceuticals, food preparation, architectural, marine applications, chemical containers, medical implants
316/316LAusteniticCold only/ non-magneticextra low carbon grade of 316marine applications, stainless steel watches, reactor pressure vessels, water reactors
321AusteniticCold only/ non-magnetichas higher stress and creep rupture properties than 304boiler and pressure vessels
347AusteniticCold only/ non-magnetichas good creep strength and oxidation resistance, but low-temperature toughnessfood processing, waste heat recovery, chemical processing, petroleum refining, pharmaceutical production
410MartensiticThermal hardening/ magneticlow cost, most widely used stainless martensitic steel, softer and more machinable than 416 or 420nuts, screws, bolts, car parts, bushings, industrial products
420MartensiticThermal hardening/ magnetichigh carbon version and harder than 410cutlery and knife blades, surgical instruments, medium quality tools
430FerriticThermal hardening/ magneticdecorative, has good formability but reduced corrosion and temperature resistanceautomotive trim
440CFerriticThermal hardening/ magnetichas greater amount of carbon, has the toughest strength in 440 variantsknife making
440FFerriticThermal hardening/ magneticfree machining variant has high carbon contentareas requiring non-galling, non-seizing, and high hardness values
446FerriticElevated Temperaturemost oxidation resistantboiler parts, burners, injector nozzles, thermocouple protectors, flame rods, glass bonding parts
