Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

After quenching and tempering, 40Cr alloy steel plate and EN10025-4 S355ML sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel en10025-4 S355ML 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.

Processing performance of quenched and tempered steel: en10025-4 S355ML plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.

Good news: In May 17th, 2018, the Myanmar navy's local representative visit our office and hot rolled plate production line, and sign another contract 2025 tons LR A shipbuilding steel plates en10025-4 S355ML order in our office. With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon cooperated with Myanmar Navy company from from 2015. They purchased 412 ton LR AH36 ship steel plate from Bebon as trial order in 2015. After receiving the goods, they speak highly of the quality and bebon's service. After that they purchase the shipbuilding steel plate from bebon regularly.
