Introduction
321 stainless steel, Ni-Cr-Mo-type austenitic stainless steel, its performance with a 304 stainless steel plate is very similar, but due to the addition of titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium to make it effective control of the formation of chromium carbide .
321 stainless steel with Ti as a stabilizing element exists, but it is the creep strength of steel at high temperatures much better than 316L.

Cold-rolled plate
1. Stretch good, toughness, but the price is more expensive;
2. Cold rolling processing surface without oxide skin, good quality;
3. Cold rolling is generally used in the production of strip, the rolling speed is high;
4. Cold rolling than the thickness of the high precision. Mechanical properties, surface and so on in the hot rolling;
5. Cold-rolled steel plate due to a certain degree of work hardening, low toughness, but can achieve better yield ratio, used for cold-formed spring and other parts;
6. Cold plate yield point closer to the tensile strength, so the use of risk in the process of no predictability, when the load exceeds the allowable load prone to accidents
7. The surface of the cold rolling plate without plating is gray.
8. Cold rolling plate plating surface smoothness is higher than the hot plate.
