Carbon steel API 5L X42 PSL2 chemical composition

Posted:2020-12-15 14:04:06

Carbon steel API 5L X42 PSL2 chemical composition is strictly controlled, and it is designed for a specific set of purposes. Carbon steel API 5L X42 PSL2 has much more advantages over API 5L X42 PSL1 steel in terms of properties, service life and durability, etc.

Carbon steel API 5L X42 PSL2 chemical composition:

API 5L PSL2	Grade	C	Si	Mn	P	S	V	Nb	Ti	Other	CEIIW	CEPcm
API 5L X42 PSL2	L290R or X42R	0.24	0.40	1.20	0.025	0.015	0.06	0.05	0.04	e,l	0.43	0.25
	L290N or X42N	0.24	0.40	1.20	0.025	0.015	0.06	0.05	0.04	e,l	0.43	0.25
	L290Q or X42Q	0.18	0.45	1.40	0.025	0.015	0.05	0.05	0.04	e,l	0.43	0.25
	L290M or X42M	0.22	0.45	1.30	0.025	0.015	0.05	0.05	0.04	e,l	0.43	0.25

e . Unless otherwise agreed, Cu≤0.50 %; Ni≤0.30 %; Cr≤0.30 % and Mo≤0.15 %.
l. Unless otherwise agreed no intentional addition of B is permitted and residual B≤0.001 %.

Carbon steel API 5L X42 PSL2 is always used to make large diameter pipes for the transportation of various mediums like gases along with and fluids of different viscosity like water, oil etc. Carbon steel API 5L X42 PSL2 is usually applied in the industries such as chemical processing, oil and natural gas, petroleum as well as petrochemical industries.
