Description
AISI 304 stainless steel (UNS S30400) is the most commonly used material in stainless steels, and is usually purchased in an annealed or cold worked state. Because SS304 contains 18% chromium (Cr) and 8% nickel (Ni), it’s also known as 18/8 stainless steel. Type 304 has good processability, weldability, corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening. SS 304 is widely used in the industrial use, furniture decoration, food and medical industry, etc. AISI 304L is the low carbon version of 304 stainless steel, AISI 303 is a free-machining steel, basically a variant of SS304, which increases the phosphorus (P) and sulfur (S) content and improves the machinability. AISI 316 is better than 304 in certain properties, corrosion resistance and heat resistance, etc. For more information, please check 304 vs 304L stainless steel and 304 vs 316 stainless steel. The following datasheet and specification show SS 304 stainless steel properties including physical properties and mechanical properties.
