How does the crack on the surface of nm500 grade material cause

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced NM500 grade material production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, NM500 grade material steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

Heat-resistant steel thick plate is made of heat-resistant steel and is processed by hot rolling. According to different structure characteristics, it can be divided into four types: austenitic type, ferrite type, martensite type and precipitation hardening type. NM500 grade material, The heat-resistant steel plate is widely used in the manufacture of petroleum, chemical equipment, boilers, steam turbines, industrial furnaces and other components and other components working at high temperatures.

The difference between Q195 steel and 20# steel: NM500 grade material, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.

Boilers with different parameters, different capacities, and different structures have different NM500 grade material, steel consumption rates. Boilers with small capacity and high steam parameters have high steel consumption. Boilers with low steam parameters mainly use low-carbon steel, while boilers with high parameters use a larger amount of heat-resistant alloy steel, and their cost is much higher. In addition, because the once-through boiler has no steam drum or downcomer, steel consumption has also been reduced.

S960Q plate implements standard EN10025-6S960Q plate application: European standard high-strength steel plate, corresponding to the national standard Q960. NM500 grade material, S960Q plate is suitable for manufacturing various construction machinery, such as drilling rigs, electric shovel, electric wheel dump trucks, mining vehicles, excavators, loaders for mining and various engineering construction, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.S960Q plate delivery status: normalizing, normalizing + tempering, quenching and tempering, etc.;Technical requirements for NM500 grade material, S960Q plate, NM500 grade material: UT, Z15-Z25-Z35 thickness direction performance requirements, high-strength and high-toughness.
