Posted:2017-01-13 04:37:45

A kind of steel under the standard of EN10025-2, it is S275JR.The grade can be bolted, riveted and welded in a full range of structural and fabricated items including bridges, box girders, cranes and other general structural projects. The minimum yield strength of the grade for thicknesses less than or equal to 16mm.JR suffixes refer to impact requirements.

S275JR Chemical composition:

C	Si	Mn	P	S	N	Cu	CEV
0.21	-	1.50	0.035	0.035	0.012	0.55	0.35

S275JR Mechanical properties:

Yield Strength (Min Mpa)				Tensile Strength ( Mpa)		Impacting Test

S275JR Application:
This are common mild steel/carbon steel plate for structural, manufacturing plant, machinery, mining equipment and vehicles, excavators, loader, bulldozers, crane, mining hydraulic supports, construction, power plant, sugar mill, palm oil mill, oil and gas, port equipments, fans, drilling rigs, power shovel and other structural parts. Heat analysis shall be used to determine the required chemical composition for carbon. Manganese, phosphorus, sulfur, silicon, and copper. Tensile strength, yield strength, and elongation shall be evaluated using tension test.

S275JR Suffixes means:
JR symbol 20 temperature impact test.
J0 symbol 0 temperature impact test
J2 symbol -20 temperature impact test
