1.4301 – European Austenitic Steel: Industrial-Grade Corrosion-Resistant Workhorse

Overview

1.4301 is a widely used European standard austenitic stainless steel, corresponding to the AISI 304 grade but with stricter chemical composition control. It is characterized by a balanced 18.00-20.00% chromium and 8.00-12.00% nickel content, forming a dense passive oxide film on the surface that provides excellent general corrosion resistance in atmospheric, fresh water, and mild chemical environments. With a face-centered cubic austenitic structure, it is non-magnetic in the annealed state, featuring outstanding ductility, cold forming ability, and weldability. This grade is cost-effective and versatile, serving as the preferred choice for general industrial and civil applications across Europe and global markets.

Chemical Composition (wt%)

C ≤ 0.08, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.045, S ≤ 0.030, Cr: 18.00-20.00, Ni: 8.00-12.00, N ≤ 0.10

Typical Mechanical Properties (Annealed Condition)

Tensile Strength (Rm): ≥ 515 MPa; Yield Strength (Rp0.2): ≥ 205 MPa; Elongation (A): ≥ 40%; Brinell Hardness (HB): ≤ 187

Core Advantages

Complies with European EN standards for strict quality control; excellent general corrosion resistance in mild environments; non-magnetic and highly ductile for complex forming; easy to weld without preheating; cost-effective and widely available in European markets.
