What is the difference between 1.4401 and 1.4310 stainless steel?
What is 1.4310 material?
The material AISI 301 is an austenitic stainless steel, also known under the designations 1.4310, BS 301S21 and X10CrNi18-8. The stainless steel AISI 301 belongs to the group of V2A steels and is also known as spring steel, as it is used for the production of technical springs.

What material is 1.4401?
The material equivalent of 1.4401 stainless steel is AISI 316. It is also known as EN 1.4401, X5CrNiMo17-12-2, and UNS S31600. This austenitic stainless steel is characterized by its chromium, nickel, and molybdenum content, providing good corrosion resistance, particularly in chloride-containing environments. 1.4401 can be processed into a variety of practical product forms, including sheet, coil, tube, rod, wire and more.

1.4401 material equivalent astm
The EN standard designation 1.4401 is equivalent to the American standard ASTM AISI 316, also known as UNS S31600.
What are the differences between 1.4401 and 1.4310 stainless steel?
1.4401 stainless steel contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, forming a stable austenitic structure. It exhibits significant resistance to pitting, crevice corrosion, and chloride environment attack, making it suitable for high-corrosion-demand scenarios such as marine and chemical industries. It also maintains good workability and weldability, though its strength is relatively moderate.
1.4310 stainless steel can achieve significantly enhanced strength (up to 1000-1300 MPa) through cold working strengthening, but it has weaker resistance to chloride corrosion. It is primarily used in springs, precision components, and other applications requiring high strength but in mildly corrosive environments.

Is 1.4401 the same as 316?
Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance.
