Sheet 68НХВКТЮ-эп578
Relevance
Products, parts, metal structures in modern production are forced to operate under very harsh conditions. They are subject to the influence of corrosive gases and solutions, high temperatures, and resist heavy mechanical loads. Sheet 68НХВКТЮ-ВИ, as well as various products, parts and structures that are made with this material, are designed for long-term operation at operating temperatures up to 800 ° C, under high loads in corrosive environments. Heat-resistant, heat-resistant sheet 68НХВКТЮ-ВИ is an example of an optimum parity of the price / quality.
