What is the nm500 vs ar500 flaw detection process
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 NM500 vs ar500 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 NM500 vs ar500 can be used bending machine mold, etc.
The smelting of NM500 vs ar500, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to have high purity. The content of sulfur, phosphorus, oxygen and nitrogen should be low, and the uniformity and stability of steel should be good. The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, spring steel must also have some characteristics.
The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, NM500 vs ar500, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.
In the use of wear-resistant plate, NM500 vs ar500, according to the different working environment, the severity of friction and wear is different. Moreover, the wear mechanism is different with different materials and working conditions. The well-known wear mechanisms include adhesive wear, corrosion wear, fatigue wear, erosion wear, fretting wear, impact wear and so on. The corrosive wear of wear-resistant plate refers to the chemical reaction or electrochemical reaction between the workpiece and the environmental medium to form corrosion products.
ASTM A537 class 1 boiler plate is pressure vessel steel. NM500 vs ar500, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.
