Anonymous users2024-02-11This material is a stainless steel material using the Soviet system, mainly because the carbon content is high, and it is easy to produce intergranular corrosion and knife corrosion.
The carbon content of American standard material 321 is an order of magnitude lower than it, which is equivalent to 0Cr18Ni9Ti in China.

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 users2024-01-29What is the difference between 1Cr18Ni9 and 1Cr18Ni9Ti? Be specific!
Dear, hello, I am glad to answer the question for you about the split pie What is the difference between 1cr18ni9 and 1cr18ni9ti The carbon content of the two is different, and 1cr18ni9ti is high. The chromium and nickel levels are the same, at 18% and 9% respectively. In this way, due to the low carbon content of 0Cr18Ni9, the strength is lower than that of 1Cr18Ni9Ti, and the corrosion resistance is better than that of 1Cr18Ni9Ti.
However, 1Cr18Ni9Ti contains titanium that is resistant to grain boundary corrosion, so its resistance to grain boundary corrosion can be improved by heat treatment. It can be used as a substitute under normal temperature and normal temperature.
Stainless steel 1Cr18Ni9Ti is an ordinary stainless steel (SUS321), and its structure class is austenitic type. 1Cr18Ni9Ti represents the content of chromium (%), nickel (%), respectively. It is a stainless steel material grade in China. >>>More
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.
