What is the nm300 wear resistance sheet continuous casting
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 nm300 wear resistance sheet and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the nm300 wear resistance sheet 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 nm300 wear resistance sheet 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.
Our quality and service commitment: nm300 wear resistance sheet product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
At present, nm300 wear resistance sheet abrasion resistant steel plate thickness is between 8-100mm, the hardness of up to 500HBW. Thin steel sheet and ultra-wide steel plate has been developed for special use.
