Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si and a small amount of Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel, Chemical composition of A709Gr50W steel. The so-called low alloy means that the total amount of alloying elements in steel is less than 3%.
High strength is relative to carbon engineering structural steel. The development principle of low alloy high strength steel is to use as few alloy elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the requirements of use and low cost.
On October 16, 2019, the Board of Directors of the World Steel Association (worldsteel) elected the following new officers for 2019/2020 at the worldsteel General Assembly in Monterrey. The new Chemical composition of A709Gr50W steel officers are elected for a one-year period: Chairman - YU Yong, Chairman, HBIS Group Co., Ltd. Vice Chairman - Sajjan JINDAL, Chairman and Managing Director, JSW Steel Limited.
Our main specifications of medium and heavy plates are thickness 6.0-180mm and width 1400-2700mm. In addition, the ship steel plate has been approved by the factories of the eight-nation classification society such as CCS, ABS, BV, LR, GL, NK, KR, and DNV. Our Chemical composition of A709Gr50W steel, medium and heavy plates are widely used in manufacturing, logistics, and automotive industries such as construction machinery, mold processing, ships, bridges, high-rise buildings, pipeline transportation, automobile girders, automobile bridge shells, and pressure vessels.
The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product Chemical composition of A709Gr50W steel more than 15 years.
