Why should JIS SM490YA plates be cut and heat treated

Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. JIS SM490YA plates, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher. The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.

The advantages of JIS SM490YA plates, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.

Hot rolled JIS SM490YA plates steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the JIS SM490YA plates processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

The high strength JIS SM490YA plates low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of JIS SM490YA plates ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve JIS SM490YA plates work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
