GB T 700 Q235B equivalent Indian standard IS2062

The most popular low carbon steel in China is GB T 700 Q235B steel, while the most popular low carbon steel in Indian is IS2062 steel. Some wonder about the differences and relations between Chinese Q235B steel and Indian IS2062 steel?

Actually, GB T 700 Q235B equivalent Indian standard is IS2062. Below is the difference and common points compared between Chinese Q235B steel and Indian IS2062 steel.

GB T 700 Q235B equivalent Indian standard IS2062 chemical composition: %

Grade	C (t≤16mm)	Si	Mn	P	S	Cu	N
Q235B	0.12-0.20	0.30 max	0.30-0.70	0.045 max	0.045 max
IS2062	max 0.23	0.40 max	1.5 max	0.045 max	0.045 max		0.012 max

GB T 700 Q235B equivalent Indian standard IS2062 mechanical properties:

Grade	Yield strength ReH/(N/mm2) (t≤16mm)	Tensile strength Rm/(N/mm2) (3mm≤t≤16mm)	Elongation A/% (3mm≤t≤40mm) min
Q235B	235 Mpa min	375-460 Mpa	25
IS2062	250Mpa min	410Mpa min	23

The chemical composition and mechanical properties of GB T 700 Q235B equivalent Indian standard IS2062 is close to that of GB T 700 Q235B steel. And some Chinese Q235B steel and Indian IS2062 steel can meet mechnical requirements of each other. But some are not. It needs the confirmation of Q/C and technical evaluation.
