What is 1.4306 stainless steel?
The 1.4306 stainless steel material is equivalent to AISI 304L and X2CrNi19-11. It's also known as Z2CN18-10 in some standards. This material is an austenitic stainless steel with a low carbon content, making it suitable for applications requiring good corrosion resistance, weldability, and formability.
What material is 1.4429 equivalent to?
EN 1.4429/ AISI 316LN (UNS S31653) is an austenitic chromium-nickel-molybdenum stainless steel. It is an enhanced version of AISI 316 with nitrogen addition which provides solid solution hardening and increased yield strength.

Corrosion Resistance
316LN alloy also offers superior resistance to pitting and crevice corrosion in chloride environments, surpassing 304 and 304L grades. It is particularly suitable for marine and chemical processing environments. Its low carbon content (≤0.03%) minimizes the risk of carbide precipitation during welding, ensuring enhanced resistance to intergranular corrosion.
What is the hardness of 1.4306 material?
The Brinell hardness of 1.4306 stainless steel (also known as X2CrNi19-11 or 304L) is typically less than 215 HB.
What is the difference between 1.4306 and 1.4307?
1.4306 is a more highly alloyed version of 1.4307 Specifically, 1.4306 contains aslightly higher percentage of chromium and a notably higher percentage ofnickel compared to 1.4307.For instance, 1.4306 typically has a nickel content of 10% minimum, while 1.4307 has an 8% minimum. Both grades are characterizedby a low carbon content, which enhances their resistance to intergranularcorrosion.
