Stainless Steel Grades

Stainless steel 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.

GRADES TYPE MAGNETISM/HARDENING DESCRIPTION APPLICATION
303 Austenitic Cold only/ non-magnetic a good machinable austenitic with its additional sulphur content. less corrosion resistant than 303 and 316 nuts, bolts, gears, etc.
304 Austenitic Cold only/ non-magnetic more suitable for complex forms than 301 kitchen appliances & sinks, truck trailers, architectural paneling, food processing equipment – milk brewing, wine making, beer brewing
316 Austenitic Cold only/ non-magnetic most expensive austenitic, has better corrosion resistance with its additional molybdenum content pharmaceuticals, food preparation, architectural, marine applications, chemical containers, medical implants
316/316L Austenitic Cold only/ non-magnetic extra low carbon grade of 316 marine applications, stainless steel watches, reactor pressure vessels, water reactors
321 Austenitic Cold only/ non-magnetic has higher stress and creep rupture properties than 304 boiler and pressure vessels
347 Austenitic Cold only/ non-magnetic has good creep strength and oxidation resistance, but low-temperature toughness food processing, waste heat recovery, chemical processing, petroleum refining, pharmaceutical production
410 Martensitic Thermal hardening/ magnetic low cost, most widely used stainless martensitic steel, softer and more machinable than 416 or 420 nuts, screws, bolts, car parts, bushings, industrial products
420 Martensitic Thermal hardening/ magnetic high carbon version and harder than 410 cutlery and knife blades, surgical instruments, medium quality tools
430 Ferritic Thermal hardening/ magnetic decorative, has good formability but reduced corrosion and temperature resistance automotive trim
440C Ferritic Thermal hardening/ magnetic has greater amount of carbon, has the toughest strength in 440 variants knife making
440F Ferritic Thermal hardening/ magnetic free machining variant has high carbon content areas requiring non-galling, non-seizing, and high hardness values
446 Ferritic Elevated Temperature most oxidation resistant boiler parts, burners, injector nozzles, thermocouple protectors, flame rods, glass bonding parts
