Low alloy steel plate was originally developed for large diameter oil and gas pipeline in 1960s. Pipeline steel materials used in oil and gas projects require higher strength and toughness than low carbon steel, and have good weldability just the same as low carbon steel.Advantages: StE355 steel material, Low alloy steel plate has superior performance and light weight.Disadvantages: Low alloy steel plate is killed steel, so the price will be more expensive.Our company was founded in 2000, which initially committed to providing high-quality steel StE355 steel material products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export StE355 steel material steel to the international market, opening up the international steel market,StE355 steel material. annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of StE355 steel material annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. StE355 steel material annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. StE355 steel material, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, StE355 steel material deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
