If used for the high temperature of 700, 1Cr18Ni9Ti should be competent, because it is not only austenitic stainless steel, but also a widely used austenitic thermal strength steel, but it is best not to exceed 750, its heat treatment is solution treatment, that is, heated to more than 1000, water quenching after a certain period of heat preservation, and then use 60 100 higher than the use temperature for aging.

5(c％。1Cr18Ni9Ti is not easy to lock up because of its higher hardness. However, because the hardness of 1Cr18Ni9Ti is relatively large, it is more difficult to process cold piers. Therefore, the ** of 1Cr18Ni9Ti is more expensive than that of 304, and the processing cost is relatively high, so now it is generally mainly made of 304 material.
At present, it is mainly used for making acid-resistant containers and equipment linings, anti-magnetic instruments, and medical devices, and has good intergranular corrosion resistance.

Anonymous users2024-02-02<> is a material with a relatively high carbon content, stainless steel. Due to the relatively high carbon content of Youxiang lead, the strength of 1Cr18Ni9Ti is not particularly low, and the corrosion resistance is not bad. However, with the development of science and technology, there is a more superb process technology for making stainless steel, and the corrosion resistance and strength of 1Cr18Ni9Ti are not very good, so 1Cr18Ni9Ti has belonged to a type of stainless steel that is close to elimination.
On some occasions in our country, there is still a place where this stainless steel process is used, but it is not recommended to feast on many occasions.
It is easy to appear intergranular corrosion in the weld area, which is mainly caused by intergranular cr poverty, which can be avoided as long as the appropriate electrode is matched to make the weld ultra-low-carbon; The knife-like corrosion in the fusion zone is also caused by poor CR; stress corrosion cracking, which is caused by the segregation of alloying elements; There is also thermal cracking, mainly caused by thermal conductivity and linear expansion coefficient, and there is attention to the formation of columnar crystals when congenetic crystallization, as long as the solidification mode is controlled, generally the weld can be inhibited by austenite + ferrite duplex structure.
