Beschreibung des Produkts

Q345B/C/D Low Alloy High Strength Structural Steel Plate

Our Q345B/C/D low alloy high strength structural steel plate is the Chinese national standard equivalent to EN S355JR/J0/J2 and ASTM A572 Grade 50, designed for demanding structural applications where weight savings and high load-bearing capacity are critical. With yield strength ≥345 MPa — 38% higher than standard A36 — Q345 allows thinner, lighter structures without compromising safety. Available in three impact-tested grades (B: +20°C, C: 0°C, D: -20°C) from 3mm to 300mm, this product is specified in Middle Eastern mega-bridge projects, Southeast Asian high-rise developments, and African infrastructure programs.

Key Features

38% Stronger than A36: Yield strength ≥345 MPa enables material down-gauging, reducing structural weight and foundation costs while maintaining safety margins
Three Impact Grades: Q345B (+20°C), Q345C (0°C), and Q345D (-20°C) with guaranteed Charpy impact energy ≥34J for applications in diverse climate zones
Microalloyed Design: Small additions of Nb, V, Ti refine grain structure for improved strength, toughness, and weldability compared to plain carbon steel
Excellent Weldability: Low carbon equivalent (CEV ≤0.45%) allows welding with standard procedures and minimal preheat requirements
Global Equivalents: Direct substitution for S355JR/J0/J2 (EN 10025), A572 Gr50 (ASTM), SM490A (JIS), ensuring acceptance across international projects
