The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, EN S355M steel plate professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better EN S355M steel plate tomorrow!

API 5L X70 pipeline steel belongs to ultra-low carbon microalloyed steel. The production of API 5L X70 pipeline steel has almost applied all the new technological achievements in the field of metallurgy for more than 20 years. API 5L X70 pipeline steel is a product with high technology content and high added value. API 5L X70 hot rolled EN S355M steel plate high strength pipeline steel is one of the important products in pipeline steel, which requires high precision of hot rolling equipment and difficult process control.

Strong pressure resistance of EN S355M steel plate, boiler steel tube: The wall thickness of boiler steel tube is very important, because the steam pressure is very large, if the wall thickness is very thin, it will be broken by the steam pressure released instantly. The boiler steel tube has good high temperature resistance performance: the steam temperature in the pipeline can reach hundreds of degrees Celsius above. If the high temperature resistance performance is not enough, the boiler steel tube will be melted by the high temperature brought by the steam.

Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of EN S355M steel plate, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.

API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, EN S355M steel plate. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.

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 EN S355M steel plate 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.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel EN S355M steel plate products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
