nm400 steel specifications Pressure Vessel Quality, PVQ Plate

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

Characteristics and application scope of NM400 steel specifications, 12Cr1MoV alloy plate:12Cr1MoV alloy plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple, the welding performance is good, but it is sensitive to normalizing cooling speed. Pearlite spheroidization will be produced after long-term use at 580 ℃.

NM400 steel specifications, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of NM400 steel specifications, Chinese grade 45 steel depends on its various properties. NM400 steel specifications, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

Laser cutting NM400 steel specifications 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 steel specifications 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.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of NM400 steel specifications, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service.
