Deskripsi produk

ASTM A572 Grade 50 HSLA Carbon Steel Plate — Bridge & Heavy Structure Grade

Our ASTM A572 Grade 50 high strength low alloy (HSLA) steel plate provides 345 MPa (50 ksi) minimum yield strength through controlled microalloying with niobium and vanadium, delivering a 38% strength advantage over standard A36 without compromising weldability. With excellent notch toughness and a low carbon equivalent (≤0.45%), this grade is the workhorse specified for highway bridges (AASHTO M270), heavy structural frames, transmission towers, and offshore platform components. We supply North American infrastructure projects, Middle Eastern bridge programs, and Southeast Asian power transmission networks.

Key Features

38% Stronger than A36: 345 MPa minimum yield allows 25-30% material weight reduction in bridge girders and structural columns while maintaining design safety factors
Excellent Notch Toughness: Fine-grain microalloyed structure provides superior resistance to brittle fracture at low temperatures compared to plain carbon steels
No Preheating Required: Low carbon equivalent (CE ≤0.45%) enables welding without preheat for most thicknesses, reducing fabrication time and energy costs
Weathering Option: Available as A572 Gr50 with Type 1 or improved atmospheric corrosion resistance (4x bare carbon steel) for unpainted bridge applications
Multi-Standard Acceptance: Directly equivalent to S355JR (EN), Q345B (GB), and SM490A (JIS) for global project specification compliance

Technical Specifications

Grade	ASTM A572 Grade 50 (Type 1)
Standard	ASTM A572/A572M, AASHTO M270 Grade 50
Thickness	6mm - 150mm
Width	1500mm - 2500mm
Yield Strength	≥345 MPa (50 ksi)
Tensile Strength	≥450 MPa (65 ksi)

Target Markets & Applications

North America: Highway bridge girders (AASHTO qualified), parking garage structural frames, industrial building columns and beams
Middle East: Cable-stayed bridge main girders, petrochemical plant heavy pipe racks, LNG tank structural support frames
Southeast Asia: Power transmission line lattice towers (345-500kV), railway bridge spans, port container crane girders
Offshore platform topside primary steel, wind turbine tower flange plates, heavy mobile crane booms

Packaging & Delivery

Plates shot blasted to SA2.5 with shop primer available. Bundled by size and heat number with steel strapping on heavy-duty wooden or steel pallets. MTC EN 10204 3.1 with full traceability from melt to delivery. Custom flame/plasma cutting to size. FOB Shanghai/Tianjin, CIF to North America, Middle East, and Southeast Asia.
