either S355 J2g3 or J0 depends on the sharpy value required
S355 is slightly stronger than Q345B, and the welding is exactly the same. S355NL grade is a normalized steel (fine-grained steel) in the EN10025-3:2004 standard. EN 10025-2 S355JR material is a low-alloy high-strength structural steel that meets the European standard EN10025. ensteelstandardcom/FAQ/what-is-the-difference-between-s355-and-q345b-steel.html
EN10025 S355J2+N structural steel has the higher Tensile of 510 MPa to 680 MPa and a Yield of 355 MPa, depending upon the structural steel thickness. ensteelstandardcom/FAQ/en10025-s355j2+n-structural-steel-plate-supplier.html
20Mn2 is not equivalent to S355. While both are structural steels, 20Mn2 is a manganese alloy steel primarily used in higher strength applications, whereas S355 is a European standard structural steel with specific yield strength requirements. The chemical composition and mechanical properties differ between the two, making them suitable for different applications. Always consult relevant material standards for precise equivalencies.
The composition of S355 is Carbon - 0.23% max Manganese - 1.60% max Silicon - 0.50% max Sulfur - 0.05% max Phosphorus 0.05% max, Copper - 0.55% max Nitrogen - 0.12% max Tensile yield minimum 490/630
The ASTM equivalent of S355 KL0 steel is typically ASTM A572 Grade 50. Both materials have similar yield strengths and are used in structural applications. However, it's important to note that there may be slight variations in chemical composition and mechanical properties, so it's advisable to consult specific material standards for precise equivalency.
S355 in bs
The minimum yield strength of S355 is 355 MPa
The Young's Modulus for EN 10149-2 S355 MC, which is a high-strength low-alloy steel, is typically around 210 GPa (gigapascals). This value can vary slightly depending on the specific composition and processing of the steel. Young's Modulus is a measure of the stiffness of the material, indicating how much it deforms under stress.
