What is EN 1.4541 stainless steel material?
EN 1.4541 stainless steel is a titanium-stabilized austenitic stainless steel with excellent corrosion resistance, good high-temperature strength, and weldability. It is commonly used in demanding applications such as aerospace and chemical processing. It has different names in different countries, such as 0Cr18Ni10Ti in China or UNS S32100/321 stainless steel in the United States.
What is AMS 5645 material?
AMS 5645 is a material specification for 321 stainless steel, a titanium-stabilized austenitic stainless steel used in aerospace and other industries. It is known for its good corrosion resistance, high strength, and toughness after heat treatment, and is used for applications that require components to be subject to high temperatures or cyclic heating and cooling.
1.4541 material equivalent asme
The ASME equivalent for the European material 1.4541 (also known as X6CrNiTi18-10) is UNS S32100, which corresponds to AISI 321 stainless steel. This is a direct equivalent with the same chemical and mechanical properties. It is an austenitic stainless steel stabilized with titanium for use in high-temperature applications.

Corrosion Resistance:
AISI 321 (1.4541, X6CrNiTi18-10) material exhibits good corrosion resistance. Its corrosion resistance is particularly outstanding in low-chlorine, low-salt natural environments, with PREN values between 17.0 and 19.0. When in contact with oxygenated water, a protective passivation layer forms on the surface; as long as this passivation layer remains intact, its corrosion resistance under normal atmospheric conditions is further enhanced.
Weldability:
AISI 321 stainless steel (1.4541, X6CrNiTi18-10) has excellent weldability and is suitable for all welding processes, such as TIG welding, MIG welding, MAG welding, and arc welding.
What is the difference between 1.4541 stainless steel and 1.4571 ?
While both are stabilized with titanium to improve high-temperature performance, 1.4571's extra molybdenum makes it suitable for more demanding, corrosive environments like those with saltwater, while 1.4541 is a cost-effective choice for less aggressive applications.
What is the difference between 1.4541 stainless steel and 1.4301 ?
The main difference is that 1.4541 (AISI 321) is titanium-stabilized stainless steel, while 1.4301 (AISI 304) is not. This makes 1.4541 superior for applications involving welding or high-temperature exposure (425-815°C) because the titanium prevents chromium carbide formation and subsequent intergranular corrosion. 1.4301 is suitable for general-purpose, lower-temperature applications where welding is not a primary concern.
