A514 Gr J alloy steel plate, High-strength steel plates are widely used in many industries such as construction, automobiles, ships, machinery and equipment, but high-strength steel plates must be selected appropriately. First, the grade is too high, which means that the price will be high because of the high manufacturing cost. Second, the low level means that the safety performance cannot meet the standard. Third, we must strictly follow the design drawings to select high-strength steel plates specifications. Fourth, it is advised the purchaser to test the high-strength steel plates with special equipment.
20# steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of 20# steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of 20# steel is not less than 250MPa;The tensile strength of 20# steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of A514 Gr J alloy steel plate and 20# steel is 7.85kg/cm3
High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the A514 Gr J alloy steel plate, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.
