The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating A709 grade 50W low alloy steel sheet production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
The company can provide the dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, markings and quality certificates of high-quality carbon structural steel hot-rolled steel plates and strips. Carbon and alloy steel grades 15Cr, 20Cr, A709 grade 50W low alloy steel sheet, 30Cr, 35Cr, 40Cr, 45Cr, 50Cr, 38CrSi, 12CrMo, 15CrMo, 20CrMo, 25CrMo, 30CrMo, 35CrMo, 42CrMo, 50CrMo, 12CrMoV, 35CrMoV, 12Cr1MoV, 25Cr2Mo1V, 38CrMoA1, 40CrV, 50CrV , 15CrMn, 20CrMn.
A709 grade 50W low alloy steel sheet, 09CuPCrNi-A corrosion-resistant steel plate belongs to ordinary low-alloy steel and steel for engineering structures; it is a high-strength corrosion-resistant steel plate. The combination of Cu and P can resist atmospheric corrosion. In addition, there are Cr and Ni, both of which are used in stainless steel. 09CuPCrNi-A corrosion-resistant steel plate is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for A709 grade 50W low alloy steel sheet.
A709 grade 50W low alloy steel sheet, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A709 grade 50W low alloy steel sheet plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A709 grade 50W low alloy steel sheet industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel A709 grade 50W low alloy steel sheet products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
