hardox 400 steel application material vs weathering steel

S420M and S420ML are hot-rolled flat weldable fine-grained structural steel with a thickness less than 120mm. HARDOX 400 steel application, S420 steel is a non-alloy structural steel. The S420ML steel is composed of the following parts: S (structural steel); 420: the yield strength value of structural steel with a thickness less than 16mm: not less than 420; M represents his delivery status, that is, hot mechanical rolling; L: The impact when the temperature is not lower than -50 degrees is marked with a capital letter L.

Boiler steel plates for room temperature and medium temperature (below creep temperature) are mostly carbon steel, including carbon steel, carbon manganese steel, carbon manganese silicon steel, HARDOX 400 steel application, etc. They are mainly used in the manufacture of pressure-bearing parts such as boiler drums and header end covers below medium temperature. High temperature (above creep temperature) boiler steel plates are mainly used to manufacture high-temperature pressure-bearing parts such as high-temperature header end caps and steam pipe blocking plates.

Laser cutting HARDOX 400 steel application has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the HARDOX 400 steel application cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
