What is Grade B Inverted Angle?

Grade B Inverted Angle typically meets marine-steel specifications like ABS or RMRS. In terms of composition, it contains carbon ≤0.21%, silicon ≤0.35%, manganese 0.8–1.2%, and both phosphorus and sulfur at ≤0.035%. On the mechanical side, it boasts a minimum yield strength of around 235 MPa, tensile strength ranging from 400 to 520 MPa, and an elongation of about 22%, striking a balance between strength, ductility, and toughness. The impact properties, often confirmed through Charpy-V tests at 0 °C, guarantee reliable performance in harsh marine conditions and heavy-load applications, making it perfect for critical structural components.
