EN steel grade S275NL material price per ton on 2020.11.03

ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. EN steel grade S275NL material, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.

Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet EN steel grade S275NL material is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.

Tempering the important EN steel grade S275NL material welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve EN steel grade S275NL material strength, plasticity and toughness.
