316/316L Cold Rolled Stainless Steel Plate External Ornaments Carbon Steel Plate

Welding Grades 310/310S are welded with matching electrodes and filler metals. The alloys are readily welded by SMAW (manual), GMAW (MIG), GTAW (TIG) and SAW. Electrodes to AWS A5.4 E310-XX and A 5.22 E310T-X, and filler metal AWS A5.9 ER310 are used. Argon is shielding gas. Preheat and post heat are not required, but for corrosion service in liquids full post weld solution annealing treatment is essential. Pickling and passivation of the surface to remove high temperature oxides are essential to restore full aqueous corrosion resistance after welding. This treatment is not required for high temperature service, but welding slag should be thoroughly removed.

Inspection :

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.
