1.4541 AISI 321 stainless steel equivalent

What is 1.4541 material ?

1.4541 is a V2A stainless steel stabilized with titanium, also known as AISI 321, Alloy 321, BS 321S31, BS 321S51, and X6CrNiTi18-10, exhibiting good corrosion resistance (PREN value 17.0 to 19.0). This material is non-magnetic (relative magnetic permeability μr < 1.3) and can be used at temperatures up to 550 °C. In the solution annealed state (at room temperature +AT), it is widely used in industries such as the automotive industry, mechanical engineering, and the chemical industry.

What is the difference between 1.4541 and 1.4301 material?

1.4301 stainless steel is low carbon chromium nickel stainless and heat resisting steel somewhat superior to Type 302 in corrosion resistance. 1.4541 stainless steel is known as stabilized grades of stainless steel, is Chromium nickel steel containing titanium.

 

What is the difference between 1.4541 and 1.4571 material?
The main difference is that 1.4541 (AISI 321) is a titanium-stabilized stainless steel based on 1.4301 (AISI 304), while 1.4571 (AISI 316Ti) is a molybdenum-containing 1.4404 (AISI 316L) grade that is also stabilized with titanium. This means 1.4571 has additional molybdenum for enhanced corrosion resistance, making it a better choice in chloride-rich environments, while 1.4541 is a more basic, cost-effective option for high-temperature applications where molybdenum is not critical.
