The toughness of steel such as A709 Gr 100W bridge steel plate is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
The mechanical properties of A709 Gr 100W bridge steel plate steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel A709 Gr 100W bridge steel plate to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.
A572 gr42 steel plate is a kind of main precision steel structure and normalizing steel. A709 Gr 100W bridge steel plate, ASTM A572 gr42, 50, 55, 60, 65 is a kind of high strength low alloy steel plate, which is widely used in factory construction, general buildings and various construction machinery, such as mining and various construction drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, hydraulic supports, mining machinery and other structures.
We have 4 typical production lines A709 Gr 100W bridge steel plate, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
