What Is 1.4541 Stainless Steel?
Material 1.4541, also known as AISI 321, is a titanium-stabilized austenitic stainless steel known for its excellent resistance to intergranular corrosion, good high-temperature strength, and good oxidation resistance up to 900°C in air. Key characteristics include its good weldability, ductility, and toughness at both high and cryogenic temperatures. It is used in applications such as automotive exhaust systems, heat exchangers, and in the chemical, food, and aerospace industries.
What is 1.4541 ASTM material equivalent to?
The European-standard EN material 1.4541 is equivalent to the American standard ASTM 321 stainless steel (also designated as UNS S32100). This titanium-stabilized austenitic stainless steel is known for its good resistance to high temperatures and corrosion, particularly intergranular corrosion. It can be processed into a variety of practical product forms, including sheets, coils, tubes, bars, and wire.

Is 1.4541 stainless steel magnetic?
No, 1.4541 stainless steel (also known as AISI 321 or X6CrNiTi18-10) is non-magnetic. As an austenitic stainless steel, its crystal structure is non-magnetic, though significant cold working or the presence of ferrite or martensite phases can increase its magnetic properties.
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.
