Date:Oct 12, 2018

By cold drawn, cold-rolled cold processing molding steel, without any heat treatment and direct delivery of the state, known as cold drawn or cold-rolled state.


Compared with the hot-rolling (forging) state, the cold drawn (rolling) state of steel, high dimensional accuracy, good surface quality, low surface roughness, and has a higher mechanical properties, due to cold drawn (rolling) state delivery of steel surface without oxide cover, and there is a large internal stress, very susceptible to corrosion or rust, thus cold drawn (rolling) state of Steel, Its packaging, storage and transportation are more stringent requirements, generally need to be kept in the warehouse, and should pay attention to the temperature and humidity in the warehouse control.
