NM360 NM400 NM500 NM550 Wear Resistant Steel Plate Flat Products Made of Steels for Pressure Purposes - alloy steels, Heat Resistant Pressure Vessel Steels
These steel grades are characterized by a good weldability. They are used above all for manufacturing boilers, pressure vessels and pipes transporting hot liquids. The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. The grades of this series offer good cold and hot-forming properties.
The Nm450 is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. The carbides in the metallographic structure are distributed in fibers, and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach HV1700-2000 or more, and the surface hardness can reach HRC58-62. Alloy carbide has strong stability at high temperature, maintains high hardness, and also has good oxidation resistance, and can be used normally within 500 ℃.

Product Show：
The steel plate is a flat steel that is cast with molten steel and pressed after cooling.
The Steel Sheet is flat, rectangular and can be directly rolled or cut from wide steel strips.
The steel plates is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot rolling plate and cold rolling plate according to rolling.
Production Process：
1. Hot Rolled Steel Plate
Hot rolling processing methods include hot rolling, forging, extrusion and other methods.
2. Cold Rolled Steel Plate
Cold rolling processing methods include cold rolling, cold drawing and cold drawing, cold bending, cold extrusion and other methods.
The cold rolling method is to continue processing the hot rolled steel below the recrystallization temperature to make it cold rolled steel. Using cold rolling processing method can improve the mechanical properties of steel, and obtain products with high dimensional accuracy and certain smoothness.
