Introduction of nm400 material specification
Wear Resistant Steel Plate refers to a special plate product designed for use under large-area wear conditions. At present, the commonly used wear-resistant plates are made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing welding with a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance. In addition, there are cast wear plates NM400 material specification and alloy quenched wear plates.
Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for NM400 material specification and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
Our alloy NM400 material specification products have complete specifications, reasonable prices and reliable quality. While supplying steel plates in stock, it can also directly place orders with steel mills according to customer needs, which can be cut for retail. Our company has established a fast logistics distribution system (delivery in time) and a sound financial system, and strive to provide you with faster, more worry-free and more valuable services!
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the NM400 material specification steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This NM400 material specification method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
