Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellentresistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800–1500°F (427–816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness. Alloy 321H (UNS S32109) is the higher carbon (0.04–0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures

Cold-Rolled Stainless Steel Plate:
a. Stretch good, toughness, but the price is more expensive;
b. Cold rolling processing surface without oxide skin, good quality;
c. Cold rolling is generally used in the production of strip, the rolling speed is high;
d. Cold rolling than the thickness of the high precision. Mechanical properties, surface and so on in the hot rolling;
e. Cold rolled steel coil due to a certain degree of work hardening, low toughness, but can achieve better yield ratio, used for cold-formed spring and other parts;
f. Cold coil 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
g. The surface of the cold rolled steel coil without plating is gray.
h. Cold rolled steel plate surface smoothness is higher than the hot rolled steel coil.
