1.4401 Stainless Steel

EN 1.4435 is an austenitic CrNiMo-Steel providing resistance to organic and inorganic acid corrosion, as well as halogen-containing media, due to its 18% Cr, 14% Ni, and minimum 2.5% Mo composition. This steel is also highly resistant to pitting.

1. What is the equivalent grade of 1.4401 stainless steel plate and its key chemical composition?

Equivalent grades: AISI 316, X5CrNiMo17-12-2. Key composition: 16.5-18.5% Cr, 10.0-13.0% Ni, 2.0-2.5% Mo, ≤0.07% C. Mo enhances corrosion resistance.
