Hardness Comparison Table of Steel from Different National Standard
Precise material selection begins with clear grade comparison. To facilitate cross-border and cross-standard business and technical exchanges for our clients and partners, Wanzhi Steel engineers have compiled the “Global Steel Grade Comparison Guide”. This guide gathers equivalent and similar grades from major standards such as Chinese GB, American ASTM, European EN, Japanese JIS, and German DIN, aiming to be your most convenient reference tool.
