Reason for unqualified inspection of nm450 plate application

DIN 34CrMo4 steel Strength, high hardenability, toughness, and quenching small deformation, high strength and creep rupture strength at high temperatures. Requirements for the manufacture of higher intensity than the 35CrMo steel NM450 plate application and tempered forging greater cross-section, such as a large locomotive traction gears, supercharger drive gear, pressure vessels, gear, rear axle, greatly affected by load and spring clip link It can also be used to 2000m deep oil drill pipe joints and fishing tools, and NM450 plate application can be used bending machine mold, etc.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's NM450 plate application steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole NM450 plate application steel transportation industry.

The preparation of NM450 plate application 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 NM450 plate application centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

Myanmar 4800 tons ABS AH36 and ABS A shipbuilding plates. This is very good customer of us, and we have cooperated many times for shipbuilding plates NM450 plate application . The most frequently ordered is shipbuilding plates, almost hundreds tons every 2 month, which are finally supplied to Myanmar’s navy. Just in last year, we have supplier more than 4800 tons shipbuilding plates for the customer continuously.

NM450 plate application, Q345R pressure vessel steel is an ordinary low alloy steel, which is commonly used for boiler and pressure vessels. The delivery status of Q345R pressure vessel steel is hot rolling or normalizing. The properties of Q345R pressure vessel steel are similar to those of Q345 steel (16Mn). The yield strength of 16mm steel plate is greater than 345 Mpa, the tensile strength is 510-640 Mpa, the elongation is more than 21%, and the zero degree V-shaped impact energy is greater than 34J. The process reference standard of Q345R pressure vessel steel is GB713.
