EN steel grade S420ML material with 6*1220*6000mm size

EN steel grade S420ML material,15Mo3 steel plate executive standard: DIN 1715515Mo3 steel plate classification: Boiler and pressure vessel steel plateApplication of 15Mo3 steel plate: 15Mo3 steel plate is mainly used to manufacture spherical storage tanks with a capacity of more than 50m3, as well as class II and III vessels such as single-layer roll welding vessels, multi-layer heat sleeve roll welding vessels, multi-layer binding vessels and low-temperature pressure vessels.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel EN steel grade S420ML material is good It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching When the hardness is HB174～229, the relative cutting workability is 60% The steel is suitable for making medium-sized plastic molds,EN steel grade S420ML material.

EN steel grade S420ML material,In actual processing applications, the processing thickness of flame cutting ranges from 6 to 200 mm, and the EN steel grade S420ML material cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting with a certain thickness above 10mm.
