EN 1.4404 Stainless Steel
EN 1.4404X2CrNiMo17-12-2AISI 316L, is a widely used austenitic stainless steel grade with excellent corrosion resistance and good mechanical properties. It is especially suitable for demanding environments such as marine, chemical processing, food equipment, and pharmaceutical applications.
In this article, we explain what EN 1.4404 means, how it compares to other stainless steels, and why it matters for buyers and engineers selecting materials for critical applications.
What Does EN 1.4404 Stand For?
EN 1.4404 is a EN 10088-1. It specifies the chemical composition and mechanical properties of a low-carbon molybdenum-alloyed stainless steel.
