Composition and performance of S275JR steel plate

Detailed explanation of S275JR steel plate:
S275JR steel plate is an ordinary carbon structural steel plate in the European standard, which is a European grade and can generally be used to manufacture engineering machinery or mining machinery with conventional or low requirements. The yield strength and tensile properties of S275JR steel plate are relatively similar to the standard grade Q275 in China, and it is usually delivered in a hot rolled heat treatment process.

Chemical composition of S275JR steel plate:
S275JR steel plate C (carbon) content → ≤ 0.21;
S275JR steel plate Mn (manganese) content → ≤ 1.50;
S275JR steel plate Cu (copper) content → ≤ 0.55;
S275JR steel plate P (phosphorus) content → ≤ 0.035;
S275JR steel plate S (sulfur) content → ≤ 0.035;

Mechanical properties of S275JR steel plate:
S275JR steel plate → yield strength → ≥ 275 MPa;
S275JR steel plate → tensile strength → 430-580 MPa;
S275JR steel plate → elongation → ≥ 23%

S275JR steel plate execution standard:
S275JR steel plate belongs to the European standard low alloy high-strength steel plate, and the standard number implemented is EN10025. This standard requires delivery conditions, technical conditions, and other standards for the steel plate.

S275JR steel plate delivery status:
The S275JR steel plate is delivered in a hot-rolled heat treatment state. If the steel plate requires inspection or Z-direction performance, the supply and demand parties can negotiate in advance and reflect it in the contract.
