Export great nm500 grade material to South Africa

The company has allocated special environmental protection facilities for all NM500 grade material pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, NM500 grade material steel mill scale, environmental protection dust has reached 100%.

15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers NM500 grade material (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).

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, NM500 grade material 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.

At present, there are many cutting methods for NM500 grade material steel plate cutting, such as common flame cutting, plasma cutting and laser cutting. Different cutting methods correspond to different cutting tools and cutting equipment. Therefore, based on this point, we can know that the answer to this question is yes, that is, there are many tools and equipment involved in NM500 grade material steel plate cutting, You can choose according to the cutting mode.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. NM500 grade material, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
