Since its establishment, the company has adhered to the business philosophy of "integrity management, reputation first, mutual benefit", and adheres to the training principles of integrity, innovation and pioneering for its employees. It has long been dedicated to EN10025-4 S420ML steel plates steel structure, shipbuilding, boiler vessel manufacturing, machinery manufacturing.

EN10025-4 S420ML steel plates smelting methodThe smelting process of electric furnace + external refining and vacuum degassing can be used for secondary electroslag remelting smelting. The steel plate should be intrinsically fine-grained steel, belonging to the 1.25Cr-0.5Mo series of pearlite heat-resistant steel, with good high-temperature strength, oxidation resistance, and sulfide corrosion resistance below 500°C. It is widely used in coal chemical industry and petroleum High temperature and high pressure vessel installation in the chemical industry.

After quenching and tempering, 40Cr alloy steel plate and EN10025-4 S420ML steel plates sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel EN10025-4 S420ML steel plates is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15 ~ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ~ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, EN10025-4 S420ML steel plates included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

Our alloy steel plate and sheets are mainly used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.Width: 1000mm to 4500mmThickness : 5mm to 150mmLength: 3000mm to 18000mmImpact tested 52° CEN10025-4 S420ML steel plates, Supply Condition: As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.

The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products EN10025-4 S420ML steel plates price concessions, rich industry experience, complete varieties.

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 EN10025-4 S420ML steel plates products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
