ASTM A572 Grade 50 vs EN S355JR (Standards & Equivalence)

ASTM A572 Grade 50 and EN S355JR are widely regarded as equivalent high-strength structural steel grades in international projects. Both grades offer a minimum yield strength around 345 MPa and are designed for load-bearing structures requiring higher strength than general structural steels such as A36 or S235JR.

In practical engineering applications, A572 Grade 50 steel coil can be used as a substitute for S355JR steel coil, provided that chemical composition and mechanical properties are verified through a Mill Test Certificate (EN 10204 3.1) and confirmed against project specifications.

Applications of A572 / S355JR Carbon Steel Coil

A572 / S355JR carbon steel coils are commonly used for:

• Structural steel fabrication and frames
• Bridges and infrastructure projects
• Transmission towers and wind tower structures
• Heavy machinery and load-bearing components

This grade is widely selected when higher yield strength is required for structural safety and cost efficiency.
