Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our A514 Gr Q high strength steel plate products have a high visibility and market share at home and abroad. At the same time, we will always bear the principle of "credit first, customer first", always put the interests of customers first, and wholeheartedly provide each of our customers with the best products and services.
The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. A514 Gr Q high strength steel plate, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..
The addition of Ca element in steel such as A514 Gr Q high strength steel plate can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
Our 1810mm production line successfully rolled 1.2mm × 1250mm ultra-thin specifications A514 Gr Q high strength steel plate high strength automotive steel, and the product quality and performance fully met the standards. In recent years, customers have become increasingly demanding for lightweight vehicles. Our company aims at the market and focuses on the development of thin-gauge high strength automotive A514 Gr Q high strength steel plate steel. The research and development personnel adjusted the product composition based on theoretical calculations and drawing on other experiences to meet customers' higher requirements for automotive steel yield strength and tensile strength.
The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!
Today, the trend of black futures remained high, and the spot market price continued to rise. However, after the rise, the overall turnover of the market weakened compared with the previous trading day, and the transaction of low-cost resources was acceptable. In terms of steel mills, the output of steel mills continues to be high, with firm ex factory prices and relatively saturated orders. A514 Gr Q high strength steel plate traders are reluctant to sell at a low price due to the high cost of taking goods, which will support the A514 Gr Q high strength steel plate price in the short term. It is expected that A514 Gr Q high strength steel plate prices will maintain a high consolidation trend tomorrow.
