Low alloy structural steel, also known as ordinary low alloy steel, HSLA steel. sa572 grade 50 Low alloy steel plates are killed or semi killed steel plates. Low alloy steel plates have the advantages of high strength, better performance, saving material and reducing the weight of structure. The thickness range of low alloy steel plates is usually 4.5-200mm.
ASTM A572 Gr.50 Low alloy structural steel is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.
As for the mechanical properties of , ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.
We supply more than 2,000 tons of high strength low alloy steel coils to support the construction of Iraq's thermal power equipment projects. As a "Belt and Road" construction project, the Iraqi thermal power generation project has high requirements on the quality of steel for power generation equipment. In particular, the flue gas baffle door sealing system of thermal power plants has extremely strict requirements on the composition, yield strength and tensile strength of steel.
Our hot rolled ASTM A572 Gr.50 low alloy steel coils have won the favor of customers for their excellent mechanical properties, standard sizes, and beautiful shapes.
