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.
stainless steel plate surface appearance and the possibility of diversification:
-
Good corrosion resistance, longer durability than ordinary steel
-
High strength, so the possibility of using the thin plate is big
-
High temperature oxidation and strength, so it can resist fire
-
Normal temperature processing, that is, easy to plastic processing
-
Because it is not necessary to surface treatment, so simple, easy to maintain, clean, high finish, good welding performance
