ASTM A514/A514M
High-strength alloy structural steel profiles
Steel Grades: Gr.A, Gr.B, Gr.E, Gr.F, Gr.H, Gr.P, Gr.Q, Gr.S
It is widely used in engineering machinery structural components, crane booms and mining equipment, as well as heavy machinery frames, support columns and beams; with its high strength, it can reduce the structural weight and improve the load-bearing and impact resistance. It is suitable for heavy load-bearing steel and load-bearing components that are welded, repeatedly subjected to high stress and impact loads, and pursue lightweight.
EN 10025-6
High-strength quenched and tempered structural steel profiles
Steel Grades: S460Q, S460QL, S500Q, S500QL, S550Q, S550QL, S620Q, S620QL, S690Q, S690QL, S690QL1, S890Q, S890QL, S960Q, S960QL
Widely used in heavy-duty engineering machinery, crane booms and mining equipment, as well as offshore platforms, bridges and large steel structures; with its high strength, it significantly reduces the structural weight and improves load-bearing and impact resistance. It is suitable for heavy load-bearing and structural steel components that are welded, pursue lightweight and high load-bearing capacity, and repeatedly withstand dynamic loads and impacts.
JIS G4104
Chromium-molybdenum steel profiles
Steel Grades: SCM415, SCM420, SCM430, SCM435, SCM440
Commonly used in mechanical transmission shafts, gears, and high-strength bolts, as well as pressure vessel components, connecting rods, and fasteners; after quenching and tempering or carburizing, the surface is hard and wear-resistant while the core is strong and tough, and it also has good hardenability. It is suitable for transmission shafts, gears, and fasteners that can withstand alternating loads and impacts and require high fatigue life and wear resistance.
