China's 1Cr18Ni9Ti is equivalent to the US AISI321, 0Cr18Ni9 is equivalent to AISI304, 1Cr18Ni9 is equivalent to 302, 0Cr18Ni12Mo2Ti is equivalent to AISI316.
If used at a high temperature of 700℃, 1Cr18Ni9Ti It should be competent, because it is both austenitic stainless steel and a widely used austenitic heat-resistant steel. However, it is best not to exceed 750℃. Its heat treatment is solid solution treatment, that is, heating to above 1000℃, keeping warm for a certain period of time, water quenching, and then aging at 60~100℃ higher than the use temperature.
3. Differences from 0Cr18Ni9
The carbon content of the two is different, 1Cr18Ni9Ti is higher. The chromium and nickel content are the same, 18% and 9% respectively.
In this case, 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, since 1Cr18Ni9Ti contains titanium that resists intergranular corrosion, its resistance to intergranular corrosion can be improved by heat treatment. It
can be used as a substitute under normal temperature and normal conditions.
1Cr18Ni9Ti is a Chinese brand corresponding to a stainless steel, so it can only be regarded as a symbol and cannot be directly understood as a chemical composition.
For example, the main materials of common stainless steel are: 0Cr18Ni9 (304), 00Cr19Ni11 (304L), 0Cr25Ni20 (310S), 0Cr17Ni12Mo2 (316), 00Cr17Ni14Mo2 (316L), 0Cr18Ni12Mo2Ti (316Ti), 1Cr18Ni9Ti, 0Cr18Ni10Ti (321), etc.
The chemical composition is:
304 stainless steel, C≤0.08 Ni8.00~10.00 Cr18.00~20.00, Mn<=2.0Si<=1.0 S<=0.030 P<=0.035; 304LC≤0.03 other elements are the same as 304
316 stainless steel, C≤0.08 Ni10.00~14.00 Cr16.00~18.00, Mo2.00---3.00 Mn<=2.0Si<=1.0 S<=0.030 P<=0.035;
316L stainless steel C≤0.03 Ni10.00~14.00 Cr16.00~18.00, Mo2.00---3.00 Mn<=2.0Si<=1.0 S<=0.030 P<=0.
The mesh size is 10mm-0.022mm (2-550 mesh), and the weaving forms include plain weave, twill (2/2 twill, 2/4 twill, irregular twill, herringbone twill). The metal wire used for the industrial mesh is drawn according to the Q/90183-2002 standard. The
wire specifications are shown in the detailed parameter table. The wire mesh material is made of high-quality brass, tin bronze, stainless steel, pure nickel, etc. The hole accuracy is divided into 1.2.3. levels (the first industrial screen produces a level 1 precision mesh).
1. Mesh series: use the priority series R20/3, R10 series, and the supplementary series R20, R40/3, R40, and select according to needs. The size specifications in the series are as follows: R20/3--1.4, R10-1.25, R40/3-1.19, R20-1.12, R40-1.06
2. Mesh size: W =L ÷ nd W-average mesh size.
L-length of adjacent mesh holes
W-average mesh hole size
d-average diameter of metal wire
Value table of L and N:
Mesh size mm Measuring length L mm Measuring number of mesh holes n
16.0-2.80 Check the length of 10 adjacent mesh holes
2.65-1.18 Check the length of 20 adjacent mesh holes
