Export great nm400 weathering steel to Australia
The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our NM400 weathering steel steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge NM400 weathering steel steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
IS 2062 E450 BR plates which have the quality of good tensile strength, excellent thickness, good elongation, good yield strength. We provide high-end finished products which have accurate dimensions, good durability i.e complete customer satisfaction. Our NM400 weathering steel plates have different applications in a number of industries such as paper, chemical, natural gas, cement industries, oils, shipbuilding etc.
The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, NM400 weathering steel, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.
Laser cutting NM400 weathering steel 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 NM400 weathering steel 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.
