1Cr 18Ni9Ti is ordinary stainless steel (SUS32 1), and its microstructure is austenite. In 1Cr 18Ni9Ti, 1, 18 and 9 represent the contents of carbon (one thousandth), 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.
Extended data:
1Cr 18Ni9T can be used at the high temperature of 700℃, because it is both austenitic stainless steel and widely used austenitic heat-resistant steel, but it is better not to exceed 750℃, and its heat treatment is solution treatment, that is, heating to 1000℃, holding for a certain time, then water quenching, and then using it is 60℃ higher than the use temperature.
1Cr 18Ni9Ti is a product representative of backward stainless steel production technology. With the improvement of production technology of stainless steel in the world, it has become an outdated product. In view of China's national conditions, it still has reservations on some occasions, but it belongs to the steel grade that is not recommended. If you really need to use 1Cr 18Ni9Ti, you can also change it to 06cr18ni1ti (0cr18ni10ti).
Whether to use 06cr18ni1Ti (0cr18ni10Ti) with ti or 06cr19ni10 (0cr/kloc) without ti?
