BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of EN 10025-6 high strength steel 1.8928 steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main EN 10025-6 high strength steel 1.8928 production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

14Cr1MoR steel plate is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other high-temperature and high-pressure large-scale equipment that is connected to hydrogen or hydrogen mixed media.
Chemical element composition of EN 10025-6 high strength steel 1.8928 container plate:
C: 0.05%-0.17%
Si: 0.50%-0.80%
Mn: 0.40%-0.65%
P: 0.010%-0.012%
Cr: 1%-1.5%

EN 10025-6 high strength steel 1.8928, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

Nickel element is mainly used to form and stabilize the austenite structure, so that the EN 10025-6 high strength steel 1.8928 steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for EN 10025-6 high strength steel 1.8928, 42CrMo steel is quenching and tempering.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
