304, 304L, 304H Stainless Steel Sheet
Grade 304 is the standard “18/8” austenitic stainless; it is the most versatile and most widely used stainless steel, available in the widest range of products, forms, and finishes. It has excellent forming and welding characteristics. Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (about 5mm and over). Grade 304H with its higher carbon content finds application at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Grade 304 can be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware, and saucepans. For severe applications, it is common to use special “304DDQ” (Deep Drawing Quality) variants.

Heat Treatment
Solution Treatment (Annealing) Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment.
Machining
A “Ugima” improved machinability version of grade 304 is available ex-mill in bar products. “Ugima” machines are significantly better than standard 304, giving higher machining rates and lower tool wear in many operations.
