The company breaks through the production limit of ultra-wide pressure vessel steel plates and can provide ultra-wide CrMo steel plates for pressure vessels over 5 meters. This breakthrough not only upgrades the manufacturing capacity of ultra-wide EN S420ML steel supplier steel plates, but also greatly improves the safety of petrochemical refining pipelines, promotes the development of petrochemical industry equipment, and promotes the high-end manufacturing of ultra-wide pressure vessel CrMo steel plates.

After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The EN S420ML steel supplier metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other EN S420ML steel supplier alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary EN S420ML steel supplier carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.

The microstructure of the quenched and tempered alloy steel, EN S420ML steel supplier after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about EN S420ML steel supplier pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
