Grade 304 stainless steel is the most versatile and the most widely used of all stainless steels. Its chemical composition, mechanical properties, weldability and ncorrosion/oxidation resistance provide the best all-round performance stainless steel at relatively low cost. It also has excellent low temperature properties and responds well to hardening by cold working. If intergranular corrosion in the heat affected zone may occur, it is suggested that CS 304L be used.
Typical Applications
CS 304 is used in all industrial, commercial and domestic fields because of its good corrosion and heat resisting properties. Some applications include:
- Tanks and containers for a large variety of liquids and solids.
- Process equipment in the mining, chemical, cryogenic, food, dairy and pharmaceutical industries.
