What is the best q355nh machinability quality

Our company's q355nh machinability power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the q355nh machinability utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

High toughness and low brittleness transition temperature: with the increase of the working pressure of the q355nh machinability gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure q355nh machinability pipeline safety, toughness and strength must be improved at the same time.

Compared with q355nh machinability, ordinary steel plate, ship plate has better resistance to wind and wave. In the ocean, there are often big winds and big waves. If the performance advantage of ship plate is not prominent, it is easy to be damaged by big waves. The service life of ship plate is longer than that of ordinary steel plate. Because of its excellent performance, the ship plate can be used for a long time. Some waste ships can remove the ship plate for recycling. The price of ship plate is higher than ordinary steel plate.

EN10025-6 S460QL structural steel plates are European standard low alloy high strength steel materials. q355nh machinability, S460QL steel plates are mainly used for building and engineering structures, such as plant structure, body steel frame components of bulldozers, loaders etc. all kinds of construction machinery, bridges, ships and so on.
