What is the meaning of AISI 304?
What is AISI 304? AISI 304 (1.4301) is a widely-used austenitic chromium-nickel stainless steel. It has excellent drawing properties and very good formability, while it is also highly corrosion-resistant. Typical uses of 304 stainless steel include sinks, kitchen equipment such as pans, tubing and much more.
What is the Rockwell C hardness of 304 stainless steel?

What is the composition of stainless steel 304?
It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. Stainless steel 304 is an austenitic grade that can be severely deep drawn.
Why is AISI 304 grade stainless steel so resistant to corrosion?
The reason why AISI 304 grade stainless steel has excellent corrosion resistance in the atmosphere is due to the formation of a chromium passivation film on its surface. But when SS304 is in a warm chloride environment, the corrosion is even faster than non-alloy mild steel.
What kind of screws are in SS 304?
