A low-alloy, high-strength steel grade with a minimum yield strength of 450 MPa is SAILMA 450 HI. At least 0.01% aluminum is present in its chemical makeup, along with a maximum of 0.25% carbon, 1.50% manganese, 0.40% silicon, 0.055% phosphorus, and 0.055% sulfur. In terms of mechanics, it offers great toughness, high impact resistance, and tensile strength of 570–720 MPa with 19% elongation. Because of these qualities, it is perfect for structural applications that call for strong weldability, high formability, and consistent performance in demanding conditions or under stress.
