I. Introduction
Heat-resistant steel is an indispensable important material in industrial production. This kind of steel has the special ability to resist the high temperature oxidation and corrosion, and very suitable in production environment with the high temperature and aggressive media. With the development of technology and changing of industrial production, more and more different country has developed their own heat-resistant steel. Thus a comparison table of the heat-resistant steels of different countries will greatly facilitate mutual comparison between them.
This article will compare Chinese heat-resistant steel brand names with the heat-resistant steels of other countries-USA, Japan, Germany and Britain. Brands of heat-resistant steel of each country and the comparison of their mechanical properties are summarized in tables.
