Stainless steel is a very common material in our daily life, for example, most of the pots and pans we use in our daily life are made of stainless steel. Stainless steel has a wide range of applications, from small stainless steel tableware to stainless steel construction and decoration materials. This article will provide a brief analysis of stainless steel, some people do not know the difference between cold rolled stainless steel and hot rolled stainless steel. At the same time, this article will provide a brief introduction to the rolling of stainless steel.
What is cold rolled stainless steel?
What is the difference between cold rolled stainless steel and hot rolled stainless steel?
What are the requirements for rolling stainless steel?
Compared to hot-rolled stainless steel, cold-rolled stainless steel can be rolled thinner strips, the current thinnest hot-rolled can be rolled about 0.78mm strip, while cold-rolled can be rolled 0.007mm metal foil cold-rolled dimensional accuracy is higher, the thickness accuracy of hot-rolled can generally reach 5%, while the highest accuracy of cold-rolled can reach 0.6%.
Different production processes
Cold rolling is rolled after the hot rolled strip has been pickled. The surface is smooth and free of iron oxide, and by controlling the surface of the rolls, it is possible to produce steel sheets in various surface states. At the same time, cold rolling can obtain a variety of different performance requirements of the steel sheet properties through the control of the press down rate or flattening elongation.
Cold rolled stainless steel differs from hot rolled stainless steel in many ways. Hot-rolled stainless steel can destroy the casting organization of the ingot, refining the grain of steel, and eliminate microstructural defects, so that the steel organization is dense, mechanical properties are improved. All in all, hot rolling and cold rolling are profile or steel forming process, they have a great impact on the organisation and properties of steel, steel rolling mainly hot rolling, cold rolling is only used for the production of small sections and thin plates.
Compared with ordinary carbon steel hot rolling, stainless steel rolling technology and process know-how, mainly in the inspection and cleaning of ingot billets, heating methods, roll hole design, rolling temperature control and product online heat treatment. The inspection and cleaning of ingot billets cleaning line includes: shot blasting, infrared surface inspection, ultrasonic flaw detection and repair grinding wheel machine. The basic requirement for rolling stainless steel is that stainless steel needs to have good strength and toughness to match, excellent low temperature toughness, non-magnetic, good processing, forming and welding properties.
