The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the A572 grade 60 CS steel carbon plate industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the A572 grade 60 CS steel carbon plate industry with scientific management, high quality, first-class service and harmonious development
If the wall thickness of the elbow is relatively thick, it is best to perform stress relief heat treatment on the weldment immediately after welding. This is especially true for large-thickness weldments Q235B, high-rigidity structural parts, and weldments that work under severe conditions (dynamic load or impact load). The tempering temperature for stress relief is 600～650℃. For thin-walled elbows, stress heat treatment is not necessary after welding.
Our SA516Gr70 pressure vessel plate has good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. The product has good dimensional tolerance and surface quality. China made A572 grade 60 CS steel carbon plate steel plates are now widely used in major chemical sites.
TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the A572 grade 60 CS steel carbon plate steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
ASTM A588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the A572 grade 60 CS steel carbon plate yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 A572 grade 60 CS steel carbon plate has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
