S355J2G3 A572Gr50 U Channel Steel

S355J2G3 is a European standard steel, the composition is: C ≤0.20, Si≤0.55, Mn ≤1.60, P≤0.035, S≤0.035. The beginning of S is structural steel, 355 means that the minimum yield strength is 355MPa. J2G3 means that the delivery state is normalized, the impact work of -20℃ is 27J, G3 and G4 are the meaning of the characterization of deoxidation mode. S355J2G3 indicates semi-killed steel. A572Gr50 low alloy high strength structural steel plates are widely used in engineering structures, such as building steel structures, construction machinery, mining machinery, heavy trucks, Bridges, pressure vessels, etc., especially for construction and engineering machinery parts requiring good weldability and toughness.

1.Products Description

A572GR50 steel is defined as high-strength low-alloy Columbium-Vanadium structural steel which belongs to ASTM A572 standard.According to the standard, structural steel is divided into five grades, namely Grade42, Grade50, Grade55, Grade60 and Grade65.Among them, Grade50 corresponds to S355J2G3, as the international equivalent steel grade.

Standard	Grade	C	Si	Mn	P	S	Nb	V
EN10025	S355J2G3	≤0.22	≤0.55	≤1.6	≤0.035	≤0.035	-	-
ASTM A572	Grade50	≤0.23	≤0.4	≤1.35	≤0.03	≤0.03	0.005-0.05	0.01-0.15

From the above chemical composition comparison,We know that S355J2G3 and A572Gr50 steel have certain differences in Mn, Nb, and V elements.Due to the difference in chemical elements, S355J2G3 is defined as a non-alloyed structural steel, while A572GR50 is defined as a low-alloyed structural steel due to the presence of Nb, V.

In terms of mechanical properties, as equivalent steel grades, their requirements on yield strength are basically the same.For low temperature impact requirements, S355J2G3 is mandatory, while A572GR50 needs to be negotiated with customers.
