1Cr18Ni9Ti stainless steel
Introduction
Stainless steel 1Cr18Ni9Ti is common. 1 1Cr18Ni9Ti carbon nickel-chromium-18 9 titanium, 1,18,9 representing carbon (‰), chromium (%), nickel (%) content
. China's stainless steel grades.
Chemical composition
Carbon C: ≤ 0.12 Si Si: ≤ 1.00 Mn Mn: ≤ 2.00 Sulfur S: ≤ 0.030 P P: ≤ 0.035 Chromium Cr: 17.00 ~ 19.00 Nickel Ni: 8.00 ~ 11.00 Titanium Ti: 5 (C% -0.02) ~ 0.80 [1]
Industry standards
Heat treatment and microstructure specifications: heat treatment specifications: 1) solid solution 920 ~ 1150 ℃ rapid cooling; 2) According to the demand side, demand may be stabilizing treatment, heat treatment temperature is 850 ~ 930 ℃, but it must be stated in the contract. Microstructure: Organizing for the austenitic type. Delivery status: normal to heat treatment delivery, the treatment types specified in the contract; not indicated, according to the heat treatment state of delivery.
Mechanical properties
Tensile strength σb (MN/m2)> = 550
Yield strength σs (MN/m2)> = 200
Elongation δ5 (%)>= 40
Shrinkage ψ (%)>= 55
Hardness: ≤ 187HB; ≤ 90HRB; ≤ 200HV
China's equivalent of the U.S. 1Cr18Ni9Ti AISI321, 0Cr18Ni9 equivalent to AISI304, 1Cr18Ni9 equivalent to 302,0 Cr17Ni12Mo2 equivalent to AISI316
1Cr18Ni9Ti = 321 = China Taiwan International Standard X7CrNiTi18-10 = Russia 12X18H10T = Japanese SUS321 = Germany X6CrNi18-10 = U.S. ASTM A276 321
If used in high temperature 700 ℃, 1Cr18Ni9Ti should be capable of, because it is an austenitic stainless steel, is very broad application of austenitic refractory steel, but preferably not more than 750 ℃, the heat of solution heat treatment , that is heated to above 1000 ℃, heat water quenched after a certain time, then the use of higher temperature to do 60 ~ 100 ℃ aging.
