S275JR/S275J0/S275J2 low alloy steel plate tensile and yield strength

Posted:2021-09-30 13:45:08

1. S275JR/S275J0/S275J2 are low-alloy high-strength steel plates, the difference lies in the impact temperature. S represents the steel structure in the steel plate grade, 275 represents the yield strength of the steel plate, JR represents the impact temperature of 20°, J0 represents the impact temperature of 0°, and J2 represents the impact temperature of -20°.

2. Chemical composition of S275JR/S275J0/S275J2 low alloy steel plate:

C	Mn	P	S	N
≤0.21	≤1.50	≤0.045	≤0.045	≤0.009

3. Tensile and yield strength of S275JR/S275J0/S275J2 low alloy steel plate:

Tensile strength（σb/MPa）	Yield strength（σ0.2/MPa）	Elongation δ（%）
430-580	≥275	≥23

4. Application of S275JR/S275J0/S275J2 European standard carbon structural steel:
They are generally used in construction and various engineering, and to make drilling rigs, electric shovel, electric wheel dump trucks, excavators, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.
