EN 1.4301 (SUS304) : EU Standard Compliance Guide

Key EU Standards & Regulations

EN 10088 Series: Specifies stainless steels, including 1.4301 (304) and 1.4307 (304L) for sheets/plates and bars/sections, defining composition & mechanical properties.

REACH & CLP (EC 1272/2008): Governs chemical safety; articles like stainless steel need Safety Information Sheets (SIS) for safe use, not full SDS.

Food Contact (EC) 1935/2004: Mandates materials don't endanger health; 1.4301 is commonly cited as suitable for food contact under this framework.

Key Compliance Aspects

Material Identification: Ensure correct grade (1.4301/304) and variants (1.4307/304L for weldability) are specified and supplied.

Chemical Composition: Must meet EN 10088 limits for elements like Chromium (Cr), Nickel (Ni), Carbon (C).

Mechanical Properties: Confirm tensile strength, yield strength, elongation (e.g., >205 MPa yield, >40% elongation).

Corrosion Resistance: Excellent in general, but avoid continuous use in 425-860°C range (use 304H or 304L) and watch for chlorides.

Application-Specific: For food/medical, verify compliance with specific EU directives (e.g., Food Contact).
