NM450 plate material name in different countries
ASTM A283 steel NM450 plate material is a carbon steel plate used for general structural purposes. This steel has low strength and medium strength. It has two steel grades (C and D). For steel coils or unheated steel plates, additional stress relief tests should be carried out. Usually, inspections, inspections, and NM450 plate material heat treatments should be carried out before leaving the factory after the coils are opened.
Weathering steel plate NM450 plate material for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate NM450 plate material has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the NM450 plate material, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
