Study on brittle phase of high chromium ferritic stainless steel00Cr26Ni6Mo4CuTi
Brittleness is a serious problem for high-chromium ferritic stainless steel.The solution and aging process tests for 00Cr26Ni6Mo4CuTi steel were carried out in laboratory.The influences of heating temperature and holding time on the brittle phase in the steel were studied, the precipitation rule of the brittle phase was found, and the influence of the brittle phase on the structure and properties of the steel was analyzed.The results showed that with fast cooling and solution process at 1 010-1 030 ℃, strength, plasticity and toughness of the steel could come up to the optimal values after 550 ℃×(3-4) h aging treatment.
