ASTM, EN, GB & JIS Steel Standards: How Equivalents Work

The same steel appears under different designations worldwide: A36≈S235≈Q235, 304≈06Cr19Ni10≈1.4301. Equivalents are close but not always identical in chemistry tolerances or mechanical minimums.

Always confirm the exact standard and intended use before substituting. Our technical team maps grades across ASTM, EN, GB, JIS and DIN for your drawings.
