Materials

Century Sun Metal Treating has thermal processes available to both harden and provide surface treatments on a wide range of materials common to the metal working industry. 

Air Hardening Materials

Steel grades containing sufficient carbon and other alloying elements to fully harden during cooling in air or other gaseous mediums from a temperature above its transformation range, e.g. A2, D2, S7, H-13 and all other hot work grades, etc. 

High Speed Steels

Primarily named for their ability to machine materials at high cutting speeds. They are complex iron base alloys of carbon, chromium, vanadium, molybdenum, tungsten or in some cases cobalt, e.g. M1, M2, T15, & CPM grades.

Carbon Steels

Steel having no specified minimum quantity for any alloying element other than commonly accepted amounts of manganese, silicon and copper, e.g. 1018, 4140, 6150, 8620, 52100, etc… Low Carbon, Medium Carbon and High Carbon Steels are common in the metal working industry and processed at Century Sun Metal Treating. 

Stainless Steel

A group of iron-base alloys containing at least 10.5% chromium that achieves their stainless properties through the formation of an invisible and adherent chromium rich oxide surface film. Austenitic, Ferritic, Martensitic and Precipitation Hardening Grades comprise the entire family of stainless steels, e.g. 416, 420, 440C, 17-4PH etc. 

Oil Hardening Grades

Steel grades that can be hardened by oil quenching or marquenching process, e.g. O1, O2, L6 etc.
