HC300LA Steel Grade: A High-Quality Material for Structural Engineering Projects

HC300LA is a high-quality, low-alloy steel grade that is suitable for use in structural engineering projects. It offers good formability and weldability, making it an ideal choice for a range of applications.

Mechanical Composition:
– Tensile strength: 340-440 MPa
– Yield strength: 240-330 MPa
– Elongation: 23-28%
– Minimum bend radius: 0.2-1.5t (t=thickness)

Chemical Composition:
– C (Carbon): 0.15% max
– Mn (Manganese): 0.5-1.5%
– P (Phosphorus): 0.025% max
– S (Sulfur): 0.015% max
– Si (Silicon): 0.03-0.5%
– Al (Aluminum): 0.02-0.1%
– Nb (Niobium): 0.09% max

These properties make HC300LA suitable for use in structural components, such as beams, columns, and trusses, where high strength and good formability are required. It can also be used in the manufacturing of automotive components, agricultural machinery, and other industrial applications.
