Differences
1.4301
1.4401 offers better chloride resistance due to Mo addition
1.4404
Also known as 316L, with lower carbon content (≤ 0.03 %) offering better weldability and lower risk of intergranular corrosion
1.4571
Similar to 1.4401 but additionally stabilized with titanium, making it more suitable for high-temperature applications
1.4401 (AISI 316) is a versatile stainless steel with excellent corrosion resistance, improved pitting resistance due to molybdenum, and good weldability and formability. It is widely used in the chemical, pharmaceutical, food, and offshore industries, as well as in swimming pool and exhaust system applications.
