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 allowable stress for S355 steel typically depends on its application and design standards. In general, the yield strength of S355 is around 355 MPa, and the allowable stress is often taken as a fraction of this value, usually around 0.6 to 0.7 times the yield strength, depending on the safety factors applied. For structural applications, this can translate to an allowable stress of approximately 210 to 250 MPa. Always consult relevant design codes for precise calculations.

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.
