Stainless Steel Grades

Stainless steel grades differ in the property and element compounds found in each which enable 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. Stainless Steels have a variation of many steel grades that are designated for various applications depending on their featured properties and strength. Stainless steel grades have their own featured characteristics that are well-suited in a variety of specific applications. 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.
Just like other steels, all stainless steel grades may greatly differ in the mechanical properties they exhibit – and this also determines in the manner of how they are machined and forged. Particular metalworking process is appropriate for an exact type of steel grade and a rigorous and thorough grade selection is necessary.
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
440CFerritic/MartensiticThermal hardening/ magnetichas greater amount of carbon, has the toughest strength in 440 variantsknifemaking
440FFerritic/MartensiticThermal hardening/ magneticfree machining variant has high carbon contentareas requiring non-galling, non-seizing, and high hardness values
446Ferritic/MartensiticElevated Temperaturemost oxidation resistantboiler parts, burners, injector nozzles, thermocouple protectors, flame rods, glass bonding parts
