Structural Bright Surface Stainless Steel Profiles SS 2520 3mm Steel Round Bar
Structural Bright Surface Stainless Steel Profiles SS 2520 Stainless Steel Round Bar
1.Introduction
2520 stainless steel is called 2520, as Cr content is 25%, Ni content is 20%, with good oxidation resistance and good corrosion resistance. It is austenitic chromium nickel stainless steel, which has excellent oxidation resistance and corrosion resistance. Because a higher percentage of chromium and nickel, 2520 has much better creep strength, and it can continue operation at high temperature, and has good high temperature resistance.

| standard | 0.08 | 1.50 | 2.00 | 0.045 | 0.030 | 24.00~26.00 | 19.00~22.00 |
| normal | 0.05 | 0.51 | 1.3 | 0.020 | 0.001 | 25.5 | 19.6 |
3.Characteristic
2520 stainless steel is a kind of high temperature resistant steel because of it’s high Ni and chromium content, it is with good oxidation resistance, corrosion resistance, acid and salt resistance and high temperature performance.
4.Application
It is sensitive to sulfur atmosphere, and shows a tendency to embrittlement of precipitated phase in 600 ~ 800 ℃. It is suitable for making all sorts of furnace with components of stress.
