15Mo3 steel plate executive standard: DIN 1715515Mo3 steel plate classification: Boiler and pressure vessel steel plateApplication of 15Mo3 steel plate: 15Mo3 steel plate is mainly used to manufacture spherical storage tanks with a capacity of more than 50m3, as well as class II and III vessels such as single-layer roll welding vessels, multi-layer heat sleeve roll welding vessels, S420ML plate multi-layer binding vessels and low-temperature pressure vessels.

Weathering steel plate is a kind of natural weathering steel plate with atmospheric corrosion resistance, characteristic corrosion and oxidation, which has been obtained in many fields. The common basic properties and the state of various weathering steel plates have been well reflected in the construction. At present, S420ML plate it is mainly used for welding and manufacturing of traffic vehicles, construction machinery, bridges, towers, containers, steel containers and other low alloy structural steel. Features: strong toughness, rust resistance, corrosion resistance, thinning and consumption reduction, energy saving.

Composition characteristics of low alloy structural steel, S420ML plate: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. S420ML plate, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, S420ML plate.

We have a professional production team and high-quality production equipment, and we also have a great S420ML plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the S420ML plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
