What is the service temperature of cutting of nm400 plate
As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.
ASTM A335 P11, P22, P91 pipes are commonly used in power plants and chemical-petrochemical industry, while P9 and P5 pipes are mainly used in petroleum refineries. BBN steel company supplies ASTM A335 Cr-Mo alloy steel seamless pipes sized from 1/2″ to 24″ranging in wall thickness from SCH20 to XXS or even thicker. The cutting of NM400 plate specification covers nominal wall and minimum wall chrome-molybdenum( also known as Cr-Mo, or Cr-Moly) alloy steel pipe intended for high-temperature application.
The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The cutting of NM400 plate, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.
The preparation of cutting of NM400 plate galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for cutting of NM400 plate centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
