321 stainless steel corresponds to the element content and performance of 0Cr18Ni10Ti (1Cr18Ni9Ti)
1Cr18Ni9Ti has been gradually replaced by 0Cr18Ni10Ti. The chemical composition of the two materials is different, so the performance is also different: 1Cr18Ni9Ti has a higher carbon content, and 0Cr18Ni10Ti has better resistance to intergranular corrosion than 1Cr18Ni9Ti, because it not only contains titanium, but also has a low carbon content, double insurance to protect chromium. But the resistance to high-temperature oxidation of the two is just the opposite.
Stainless steel 0Cr18Ni10Ti 0Cr18Ni10Ti (GB/T 1220-1992) adds Ti elements to 304 steel to prevent intergranular corrosion; it is suitable for use at temperatures of 430℃~900℃. It is used in aircraft, exhaust pipes, boiler drums, etc.

The difference between 1Cr18Ni9Ti and 0Cr18Ni10Ti
1. Element difference
1Cr18Ni9Ti C ≤ 0.12 Si ≤ 1.00 Mn ≤ 2.00 P ≤ 0.035 0.03 8.0-11.0 17.0-19.0 5(C%-0.02)0.8 S ≤ Ni Cr Ti 0Cr18Ni10Ti C ≤ 0.08 Si ≤ 1.00 Mn ≤ 2.00 P ≤ 0.035 0.03 9.0-12.0 17.0-19.0 S ≤ Ni Cr Ti ≥5*C%
Remarks: From the perspective of element composition, the main reason is that the C content of 0Cr18Ni10Ti is lower. From the perspective of intergranular corrosion resistance, C The ones with low C content have better resistance to intergranular corrosion. (In addition, there is no 0Cr18Ni9Ti in the national standard, but the C content of 1Cr18Ni9Ti currently produced on the market is generally lower, and the composition is within the range of 1Cr18Ni9Ti. Therefore, it is called this way.)
2. Difference in mechanical properties after solution treatment Material (MPa) Yield point б 0.2 Tensile strength б b (MPa) Elongation δ (%) Sectional shrinkage Ψ% Hardness HB Impact value AK (J) 1Cr18Ni9Ti 205 520 40 50 187 -- 0Cr18Ni10Ti 205 520 40 50 187 -- Remarks The solution temperature is 920-1150 degrees, and the mechanical properties are the same after heat treatment, but there will be differences after actual production, because the C content of 0Cr18Ni10Ti is low, and the Ni A high content will make the material softer. In terms of mechanical properties, yield and elongation。
