1, stainless steel 1Cr 18Ni9Ti is ordinary stainless steel (SUS32 1), and its microstructure is austenite. 1, 18 and 9 in 1Cr 18Ni9Ti represent the contents of carbon (%), chromium (%) and nickel (%) respectively. It is a stainless steel brand in China. Used for manufacturing acid-resistant containers and equipment linings, magnetic instruments and medical instruments, with good intergranular corrosion resistance.
2, heat treatment specification: 1) solid solution 920 ~ 1 150℃ rapid cooling; 2) It can be stabilized according to the requirements of the buyer, and the heat treatment temperature is 850 ~ 930℃, but it must be specified in the contract.
3. Metallographic structure: the structure is austenite. Delivery status: generally, the goods are delivered in heat treatment status, and the type of heat treatment is indicated in the contract; If there is no stipulation, the goods shall be delivered without heat treatment.
4. The carbon content of the two materials is different, and 1Cr 18Ni9Ti is higher. The contents of chromium and nickel are the same, which are 18% and 9% respectively. In this case, the strength of 06cr19ni10 (0cr18ni9) is lower than that of 1Cr 18Ni9Ti and lower than that of1Cr/kloc-8. However, because 1Cr 18Ni9Ti contains titanium with grain boundary corrosion resistance, its grain boundary corrosion resistance can be improved by heat treatment.
5. The United States and Canada provide imported 1Cr 18Ni9Ti spectral and chemical standard samples, and the corresponding standard samples include American Bureau of Standards (ASTM), German standards and French standards. , with good uniformity, is mainly used in spark direct reading spectrometer and X-ray fluorescence spectrometer (XRF).
