Stainless Steel SUS304
Stainless steel SUS304
SUS304 (stainless steel 304) is the world’s most widely-used stainless steel, accounting for about 50% of the stainless steel produced globally. Containing 18% Chromium and 8% Nickel, SUS304 stainless steel is resistant to corrosion in certain environments as air, sea water and acids. Therefore, they are applied in many fields from petroleum, food, pharmaceutical to marine.
There are 2 types of SUS304 (aka inox 304):
- 304L is a low-carbon stainless steel (the letter L stands for Low) and it is used to avoid corrosion in critical welds.
- 304H is a type with a higher carbon content than 304L, used in other fields where higher durability is required.
- Both SUS304L and SUS304H exist in sheet and tube form, but 304H is less commonly produced.

Manufacturing Ability
Starting temperatures of 2000F to 2100F are recommended for forging, with a suggested finish temperature above 1400F. The final usable forging temperature for Type 403 is 1300F. In addition, this material has better mechanical properties obtained in the forging and annealing condition at lower temperatures.
In addition, product hardening can be performed at temperatures ranging from 400F to 1400F. The strength and hardness of Type 403 will decrease at 800F while toughness increases with annealing temperature.
Application
