Leave a message
What is 1.4404 stainless steel material?
1.4404 is a low-carbon, austenitic stainless steel that is also known as AISI 316L. It is highly resistant to corrosion due to its molybdenum content and is known for its excellent weldability and suitability for a wide range of applications, particularly in the chemical, pharmaceutical, and food industries.
what is X2CrNiMo17-12-2 equivalent?
X2CrNiMo17-12-2 is equivalent to 316L (AISI), 1.4404 (Werkstoff number), and S31603 (UNS), among others. These designations refer to the same type of austenitic stainless steel, which is known for its high corrosion and heat resistance.
What material is equivalent to 1.4401 1.4404?
Materials 1.4401 and 1.4404 are equivalent to 316 stainless steel (1.4401) and 316L stainless steel (1.4404) respectively, with the main difference being the carbon content. 1.4404 is the low-carbon version of 1.4401, making it better for welding, while both are molybdenum-containing austenitic stainless steels with excellent corrosion resistance.

X2CrNiMo17-12-2 vs 316L
X2CrNiMo17-12-2 and 316L are the same material, representing different naming conventions for the same low-carbon, austenitic stainless steel. X2CrNiMo17-12-2 is the European standard designation (EN), while 316L is the American standard (AISI) designation. The 'L' in 316L signifies its low carbon content, which improves its weldability and resistance to intergranular corrosion compared to standard 316 steel.
What is the difference between 3CR12 304 and 316?
What differs 316 from 304 is a mineral called molybdenum. With the addition of 2-3% molybdenum, 316 provides heavy-duty corrosion resistance to oxidisation and chloride-based exposure. 3CR12 provides similar corrosion and heat resistance properties as 304 and 316, with the added benefit of weldability and formability.
