The difference of hot rolling stainless steel and cold rolling stainless steel

Hot rolling is above the recrystallization temperature of rolling; Cold rolling is below the recrystallization temperature of rolling, both are based on the hot strip rolling.And then recover its mechanical properties by annealing . It generally underprocess such as hot rolling,acid pickling, cold rolling and annealing.


There is no oxide coating during cold rolling process. Inthis way, the surface of the cold rolling stainless steel will be good and inhigh size precision.


There will be oxide coating in hot rolling process. Itwill make the bad tolerance of stainless steel plate and not good in smoothnessand toughness. And the price of hot rolling stainless steel product will belower.
