3584 tons EN steel grade S275J2 material building steel plate to Iran

We have 4 typical production lines EN steel grade S275J2 material, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of EN steel grade S275J2 material and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.

The chemical composition difference between EN steel grade S275J2 material, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between EN steel grade S275J2 material, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
