What harm does the excessive weld height of nm400 wear resistant plate bring
Our company has NM400 wear resistant plate strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply NM400 wear resistant plate deep processing service for products NM400 wear resistant plate like cutting, drilling, bending, welding and grinding.
Is there a difference between seamless steel pipe and ordinary steel pipe? The general requirements of NM400 wear resistant plate ordinary steel pipe are not so high, which are used in ordinary buildings or structures. According to the different materials and standards, seamless steel pipe will have different application environment. For example, seamless steel pipe for boiler requires pressure value. Seamless steel pipe for petroleum cracking also has its own corresponding national standard. Seamless steel pipe can be divided into fluid pipe, gas cylinder pipe, boiler pipe, oil pipe, automobile steel pipe, ship pipe, structural pipe, etc.
Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the NM400 wear resistant plate steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
WTST 37-3 steel plate is a kind of carbon steel plate. WTST 37-3 steel plate can be used to build low temperature sea water resistant containers. When the customer orders NM400 wear resistant plate WTST 37-3 steel plate from us, our factory should roll it in full accordance with SEW 087-2 specification, and the factory will issue the original mill test certificate for inspection before delivery.
Q235 is a kind of carbon steel. NM400 wear resistant plate, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance. Q235A steel plate contains C ≤ 0.22%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.050, P ≤ 0.045. Q235B steel plate contains C ≤ 0.20%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.045, P ≤ 0.045. Q235C steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.040, P ≤ 0.040. Q235D steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.035, P ≤ 0.035.
Our company will accept the product quality objection registration record, pass it to the NM400 wear resistant plate production unit and relevant departments, and timely coordinate the supervision of product NM400 wear resistant plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
