Effect of heat treatment process on microstructure and properties of EN steel grade S275N material

The company always adheres to the EN steel grade S275N material principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great EN steel grade S275N material cause. Customers are welcome to visit our company at any time. We are always ready to support you.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's EN steel grade S275N material steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole EN steel grade S275N material steel transportation industry.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of EN steel grade S275N material, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

In 2016, we brought our customer to visit our NM400 hot rolled plate; producing line and our shanghai warehouse for 30,000 tons plate and structure. As a result, Our client purchased 500 tons NM400 as first order, which is shipped by 3 times. In future. Our company will always guarantee that all the delivery condition for Hardox plate EN steel grade S275N material provided will be with quenching and tempering, which is the best delivery type according GB/T 24186 standard.

StE 480.7 TM steel plate/pipes,under DIN 17172 standard, we can regard StE 480.7 TM steel plate/pipes as large diameter pipes. EN steel grade S275N material, StE 480.7 TM steel plate/pipes is one mainly of Steel for large diameter pipes,DIN 17172 StE 480.7 TM steel with the demands in mechanical properties of the pipes followed the DIN 17172 specification for grade StE 480.7 TM(YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

Aspire to technological innovation and pursue first-class quality steel EN steel grade S275N material products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.
