STAINLESS STEEL GRADES

Stainless steel bar grades differ in properties and elemental compound composition and as such, Forte Precision Metals offers a stainless steel round bar stock in numerous grades.

These stainless steel bars are evaluated and grouped according to the machining process they will undergo whether cold-rolling, hot rolling, or precision grinding processes. 

These particular metalworking processes, which Forte Precision Metals offers, bring out the best of the stainless steel, and depending on its expected application, they will end up having a finished product of either cold-rolled bar, cold-rolled steel bar, precision-ground steel bar, or an entire precision ground bar stock.  

However, one cannot just simply use any stainless steel grade for whatever industrial application, it is necessary that the appropriate stainless steel grade is used according to a specific industrial application. 

By classifying them into appropriate stainless steel grade, proper machining and grinding applications will be used to transform round bars into a hot rolled bar, cold rolled bar, cold-rolled steel bar, precision-ground steel bar, or an entire stock into precision ground bar stock. 

Below is a list of the grades of the stainless steel round bar stock that Forte Precision Metals, your trusted stainless steel round bar supplier, offers:

GRADETYPEMAGNETISM / HARDENNINGDESCRIPTIONAPPLICATION
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
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 / agneticfree 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
