The company is a large A709 grade HPS100W bridge steel plate steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the A709 grade HPS100W bridge steel plate enterprise, and make our own contribution to the development of the world economy.
As a pipeline of oil and natural gas, spiral pipe has its own characteristics: 1. The amount of use is large, because the specifications of A709 grade HPS100W bridge steel plate, spiral pipe used in a project are often diversified. During the forming process of the spiral pipe, the steel plate deforms evenly, the residual stress is small, and the surface does not occure scratches. 2. The spiral pipe is used in a complex environment, and the quality must be guaranteed, otherwise it will delay the follow-up project progress.
Heat treatment advantages of A709 grade HPS100W bridge steel plate, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
The purpose of A709 grade HPS100W bridge steel plate quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of A709 grade HPS100W bridge steel plate. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
A709 grade HPS100W bridge steel plate, Q460D quenched and tempered steel plate spot specification: 6*2000*8500, 6*2000*10800, 45*1550*4900, 16*2000*9700, 14*1950*7030, 22.23*2181*12200, 28*2010*7300, 23.83*2179*5000, 19*2500*6000, 23.83*2179*5000, 28.58*2171*12300, 28.5*2340*12150, 28.58*2171*11500, 28.58*2171*10800, 22.23*2150*12200, 28.5*2000*12150, 28.58*2172*11500, 28.58*2172*10800, 28.58*2172*12100, 25.4*2298*13000 (mm).
