Hot rolled NM450 steel grade mechanical properties

The strength of NM450 steel grade, 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing. Arc welding and contact welding have good welding performance and small thickness during gas welding. Cracks are likely to occur on parts with strict shape requirements or complex shapes.

For a ship, the choice of medium and thick ship plate is very important, it is an important part of the ship frame. The pressure bearing capacity of NM450 steel grade, medium and thick ship plates is very strong. Secondly, because it is a ship plate, it must be driven in water, so of course the corrosion resistance is better, otherwise it will bring danger to buyers. Moreover, the service life of the ship will be increased. Regular inspection of the ship plate can ensure the safety of sailing. You can also know whether the ship plate is defective, so you don't have to worry about water seepage when you sail.

Processing performance of quenched and tempered steel: NM450 steel grade plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.

We have huge stocks for carbon steel plates, high strength low alloy steel materials, weather resistant steel sheets, wear resistant steel plates, boiler plates, pipeline steel, etc. Those stocks can be delivered within 10 days after deposit. We update NM450 steel grade stock list regularly. But the stock changes quickly. It needs to check with warehouse specially when you have urgent needs. Welcome to contact us and book steel materials stocks.
