What is chemical composition and mechanical properties of S550QL EN 10025-6 high strength steel

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the S550QL EN 10025-6 high strength steel hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the S550QL EN 10025-6 high strength steel steel industry.

Steel S275J0 is a carbon structural steel grade. Our mill can produce S275J0 carbon steel plates up to 400mm thickness. Generally speaking, as rolled condition for S275J0 carbon steel plate is Ok. Our mill would like to provide customers' normalized delivery condition if they indicate in their purchase order. S550QL EN 10025-6 high strength steel, Structural steel S275J0 has a specified minimum yield strength at ambient temperature of 275MPa when plates thickness less than 16mm.

Compared with carbon steel, alloy steel has higher strength, better heat resistance, better low temperature resistance, better corrosion resistance and other advantages. Some of its work environment can not be adapted by carbon steel. Therefore, alloy steel is a common and important material in pressure pipeline. Low alloy steel, S550QL EN 10025-6 high strength steel quenched and tempered steel, stainless steel, heat-resistant steel and low temperature steel are commonly used in pressure pipes.

S550QL EN 10025-6 high strength steel, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of S550QL EN 10025-6 high strength steel, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

If you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time. Other than fresh production, we also have huge S550QL EN 10025-6 high strength steel stocks for the most widely used steel materials. So that the customers need not wait too long to get their required steel. Welcome to contact us and consult steel price, our sales person will give you professional answers and suggestions.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
