Our company was founded in 2000, which initially committed to providing high-quality steel BS EN10025 / S460 ML products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export BS EN10025 / S460 ML steel to the international market, opening up the international steel market.

ASTM A387 steel BS EN10025 / S460 ML specification refers to 6 grades levels of alloy steel plate for elevated temperature applications, classified by chromium and molybdenum content, Grade 11 and Grade 12 has similar chemical content,they can be used in welded BS EN10025 / S460 ML pressure vessels and industrial boilers, and mostly in oil gas and petrochemical industry, generally it is used for transportion of medium at high temperature.

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. BS EN10025 / S460 ML, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. BS EN10025 / S460 ML, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For BS EN10025 / S460 ML ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the BS EN10025 / S460 ML standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
