What is 1.4372 stainless steel?
1.4372 stainless steel, also known as AISI 201 or X12CrMnNiN17-7-5, is an austenitic stainless steel with good strength, ductility, and weldability. Due to its lower nickel content and higher manganese content, it is an affordable alternative to higher nickel content stainless steels (such as 304 (1.4301)).
What is the equivalent of 1.4372 stainless steel?
What is the equivalent of 1.4372 stainless steel? Stainless steel grade EN 1.4372 is equivalent to AISI 201. It is also known by other names such as UNS S20100 and is a chromium-nickel-manganese austenitic stainless steel.

What is the composition of stainless steel 1.4372?
Stainless steel 1.4372 (also known as AISI 201) is an austenitic stainless steel with a composition of approximately 16.0–18.0% chromium, 3.5–5.5% nickel, 5.5–7.5% manganese, and 0.05–0.25% nitrogen. It contains a maximum of 0.15% carbon, up to 1.00% silicon, and a maximum of 0.060% phosphorus and 0.030% sulfur.

Is 1.4372 SS stainless steel magnetic?
No, 1.4372 SS (also known as AISI 201) stainless steel is generally considered non-magnetic when annealed (heat-treated to relieve internal stresses).
What are the differences between 1.4372 and 1.4301 stainless steel?
The main difference is that 1.4301 (AISI 304) is a standard austenitic stainless steel with a higher nickel content, offering superior corrosion resistance and formability; while 1.4372 (AISI 201) is a substitute steel with a lower nickel content and a higher manganese content, offering higher strength but slightly lower corrosion resistance, especially in high-chloride environments.
