摘要： Austenitic steel having an excellent resistance to high temperature oxidization. The steel contains carbon up to 0.01 percent, silicium 0.1-5 percent, manganese up to 3 percent, nickel 7-45 percent, chromium 15-30 percent and sulphur 0.003 percent or less. The low content of sulphurO.003 percent or less, preferably 0.0015 percent or less, makes the steel resistant to oxidization even if exposed to a number of heat cycles between a high temperature and room temperature.
