Is AISI 304 stainless steel?

AISI 304 (1.4301) is a widely-used austenitic chromium-nickel stainless steel. Type 304 is sometimes also referred to as 18/8, a moniker that comes from its typical composition of 18% chromium and 8% nickel.

What is the difference between AISI 304 and SS 304?

SUS304 (SUS meaning Steel Use Stainless) stainless steel austenite is typically known as the Japanese name for SS304 or AISI 304. The main difference between the two materials is not any physical property or feature, but how it is referenced in American and Japanese grades.

What is the meaning of AISI 316?

AISI 316 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 316 is the AISI designation for this material. S31600 is the UNS number. Additionally, the British Standard (BS) designation is 316S16.

What does AISI stand for in stainless steel?

American Iron and Steel Institute
Back in the 1930s and 1940s, the standards organization SAE International and the American Iron and Steel Institute (AISI) began working to standardize a numbering system for stainless steel.

What is the difference between AISI and SS?

Stainless steels, thanks to their chemical composition, are metal alloys, which are naturally corrosion resistant. AISI316L stainless steel, known as 1.4404, is different from AISI 316 (1.4491) stainless steel because it has less carbon inside. On the contrary, in AISI 316 it must be ≤ 0,07.

What does AISI mean in steel?

The coding system is known for its efficient classification of steels as it uses the standards from the American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.).

Why is 304 stainless steel rusting?

Stainless steel contains chromium, and when exposed to oxygen it forms a thin invisible layer called chromium oxide. Rust can form when this layer is damaged from exposure to cleaners, chloride, high humidity, high salinity environments, and/or mechanical abrasions.

What AISI means?

The coding system is known for its efficient classification of steels as it uses the standards from the American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.). Grades for alloy steels and carbon steels were identified by this system based on standard chemical compositions.
