After quenching and tempering, 40Cr alloy steel plate and EN S420ML standard pdf sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel EN S420ML standard pdf 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.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of EN S420ML standard pdf, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon Cooperate with Myanmar Navy from from 2015. They purchased 412 ton EN S420ML standard pdf LR AH36 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. In May,2018, the Myanmar navy's local representative visit our office and production line, and sign another contract 2025 tons EN S420ML standard pdf LR A shipbuilding steel plates order in our office.
