At present , common carbon steel+ceramic lining plate are generally used for high temperature and wear re- sistant components in domestic metallurgy, coking and other industries, with poor safety, high component weight and cost , however, high temperature and wear resistant steel can effectively meet needs on lightweight , longer service time and cost saving for key components in metallurgical and other industries. NM450HiTemp is a high temperature and wear resistant steel, which can provide a cost-effective and wear-resistant solution under high temperatures ranging from 300 to 500°C.
