nm450 plate impact resistance for high temperature service

Our company has NM450 plate impact resistance strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply NM450 plate impact resistance deep processing service for products NM450 plate impact resistance like cutting, drilling, bending, welding and grinding.

NM450 plate impact resistance, 45# steel is carbon steel, belonging to high strength medium carbon quenched and tempered steel, with carbon content of 0.45%, so it is called 45# steel. 45# steel does not contain specially included alloy elements. NM450 plate impact resistance, 45# steel is one of the most widely used high-quality structural steel. 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.

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, NM450 plate impact resistance weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized NM450 plate impact resistance are higher than that of annealed NM450 plate impact resistance, but the elimination of internal stress is not as good as annealing. The normalizing operation of NM450 plate impact resistance is simple, the cost is low, the productivity is high, and it is widely used in actual production.
