S275JR is a carbon structural steel and low alloy structural steel for engineering and structural steel, with a yield strength of 275MPa. This steel plate belongs to the European standard low-alloy high-strength structural steel plate, and the implementation standard is the special technical conditions of EN10025. It may also be produced according to the WJY steel mill enterprise standards.

The specific requirements for the chemical composition of S275JR are as follows:

C	Si	Mn	P	S	N	Alt
0.16%~0.18%	≤0.55%	1.50%~1.60%	0.040%~0.030%	0.040%~0.025%	≥0.012%	≥0.015%

The production method of S275JR mainly includes the following steps: raw material preparation, molten steel refining treatment, molten steel vacuum treatment, mold casting or continuous casting, heating, steel plate rolling, steel plate heat treatment, steel plate cutting and inspection, and warehousing.

S275JR steel plate has several notable features. The following are its main features:

1. Strength and toughness: The yield strength of S275JR steel plate is 275MPa, the tensile strength range is between 430-580MPa, and it has high strength and toughness. This allows it to maintain good stability and reliability when subjected to heavy loads and stresses.
