The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep A709 Gr 50W low alloy steel sheet processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and A709 Gr 50W low alloy steel sheet steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.
A36 steel is the code of American ASTM Society for carbon steel. ASTM A36 steel A709 Gr 50W low alloy steel sheet is the most commonly used steel in construction. Unlike high-performance alloys, the properties of A36 steel enable it to be used in many fields. A36 steel is very popular in building application!
Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate A709 Gr 50W low alloy steel sheet has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A709 Gr 50W low alloy steel sheet carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A709 Gr 50W low alloy steel sheet alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
A709 Gr 50W low alloy steel sheet, S235JR VS S275JR VS S355JR plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
The results of adopting two-level A709 Gr 50W low alloy steel sheet service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and A709 Gr 50W low alloy steel sheet after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
