The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural S355ML properties steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

40CrMo alloy structural steel specification Grade: 40CrMoStandard: GB/T 3077-1988Mechanical properties:Tensile strength σb (MPa): ≥1080 (110)Yield strength σs (MPa): ≥930 (95)Elongation rate δ5 (%): ≥12Section shrinkage ψ (%): ≥45Impact energy Akv (J): ≥63Impact toughness value αkv (J / cm2): ≥78 (8)Hardness: ≤ 217HBSample size: Sample blank size is 25mm

High wear resistance: fully automatic CNC stacking equipment, independent of manual S355ML properties welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the S355ML properties hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite S355ML properties wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

Alloy steel plate is formed by adding alloy elements into steel. In this process, the basic elements of steel, namely iron and carbon, will have a certain effect with the newly added alloy elements. Under this effect, the structure and material in the steel will have certain changes, and the overall performance and quality of steel will also be improved. Therefore, the output of S355ML properties, alloy steel plate is increasing, and its application range is more and more extensive.

"We can supply carbon steel plate, S355ML properties, hot rolled plate and structural steel sheet with high quality and various size. Thickness from 5mm to 300mmWidth: from 1,500mm to 2,500mmLength: from 6,000mm to 12,000mmTechnical conditions: Ultrasonic tested as per SA 578 or any other as per requirementMTC acc to EN 10204 / 3.2"

It is a modern high-tech professional enterprise integrating scientific research, S355ML properties production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as S355ML properties process technology development, technology transfer and related technical consulting and technical services.

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.
