S355ML grade for construction machinery components

The S355ML grade processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the S355ML grade steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.

In actual processing applications, the processing S355ML grade thickness of flame cutting ranges from 6 to 200 mm, and the S355ML grade 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 S355ML grade with a certain thickness above 10mm.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the S355ML grade plate should be derusted before cutting.

The company will regularly hold the award ceremony for excellent employees. he award-winners prove their excellence and the team’s excellence with S355ML grade great achievements.On Oct., 2018 the Management star is Ms. Sherry from International Trade Department. The sales star is Ms. Katrina from International Trade Department. Under the guidance of Ms. Sherry, the old customer maintenance team of S355ML grade BBN steel completed 309% sales task in Oct., 2018. Ms. Katrina has been using her own actions to interpret the "pursuit of excellence, continuous innovation" spirit of BBN enterprise.
