Wnm-abrasion Resistant Steel Plate

Heat affected zone (HAZ) is the weakest half in a welding joint and is probably the most possible location for the generation of welding chilly crack. In this paper, the results of preheating temperature and warmth input on welding cold crack sensitivity of NM360 steel have been studied through the use of implant tests. It is found that the preheating temperature and interlayer temperature throughout CO2 arc welding of NM360 metal should be 100 °C or a hundred twenty five °C to prevent the prevalence of welding chilly crack. The important rupture stress and rupture time underneath excessive stress may be improved significantly with a high enough preheating temperature. However, heat input enhance has little impact on critical rupture stress.

Wzb-nm Steel Chemical Composition:

NM360 steel

Suitable structural metal plates for the processing and manufacturing of wear resistant and weak parts for mines and varied engineering equipment. It produces greater than 5000 tons of nm400 metal plate for construction equipment, mining machinery, coal mining equipment, environmental protection machinery, metallurgical equipment and different manufacturing enterprises, similar to excavator, loader, bulldozer bucket plate, edge plate, side blade plate, blade, crusher liner and blade development project. The prospect of exporting to the United States, Canada, Australia, India and Europe is a good prospect.

  • The surface hardness of the product is often 360 to 450HB.
  • Suitable structural steel plates for the processing and manufacturing of wear resistant and vulnerable components for mines and varied engineering machinery.
  • Its mechanical properties are three occasions to five occasions that of strange low alloy metal plates, and it could considerably enhance the damage resistance of mechanical parts.
  • Therefore, the service lifetime of equipment and the manufacturing price are reduced.

Gb Nm360 Wear Resistant Steel

Its mechanical properties are three instances to 5 instances that of strange low alloy metal plates, and it can considerably improve the wear resistance of mechanical parts. Therefore, the service lifetime of equipment and the manufacturing value are decreased. The surface hardness of the product is often 360 to 450HB.

It has been supplied for greater than tons of European clients. NM360 Wear-resistant steel plate,NM360 and NM400 wear-resistant metal plate is extensively utilized in mining equipment, coal mining equipment, environmental protection machinery, engineering equipment, cement machinery, metallurgical equipment, brick equipment and other products components. Also used as a yield energy ≥ 700Mpa excessive strength structural steel.

High energy wear resistant metal plate due to its wonderful abrasion resistance and processing ease of use is used by the increasingly more enterprises. Company steel plate processing manufacturing unit can minimize the semi-finished merchandise and special-formed merchandise based on consumer necessities, on the similar time to move. NM400 wear-resistant metal plate is widely used in engineering equipment, mining machinery, coal mining equipment, environmental protection machinery, metallurgical equipment and other merchandise. Excavator, loader, bulldozer bucket board, blade plate, side blade plate, blade. Due to the excessive quantity of carbon and diffusible hydrogen, high-energy wear-resistant steel NM360, which is broadly used on excavating machinery, always tends to develop cold crack after welding.
