What is A514 Gr Q steel material used for?

The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with A514 Gr Q steel material good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.

20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. A514 Gr Q steel material, 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 A514 Gr Q steel material, 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.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, A514 Gr Q steel material. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.

A514 Gr Q steel material product plate specification range:Thickness 3-150mmWidth 1500-4020mmLength 4000mm-17000mmHeat treatment: annealing, or normalizing and tempering

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s A514 Gr Q steel material domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

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.
