hot and cold rolled 310s stainless steel plate
1, hot and cold rolled 310s stainless steel plate prices and thickness of the price difference of about 2200 or so.
2, hot rolling is relative to cold rolling, cold rolling is carried out under the recrystallization temperature of the rolling, and hot rolling is more than the recrystallization temperature of the rolling. Its advantages are:
(1), hot rolling can significantly reduce energy consumption and reduce costs. Hot metal plastic high, deformation resistance is low, greatly reducing the energy consumption of metal deformation.
(2), hot rolling can improve the processing performance of metals and alloys, that is, the casting of coarse grain crushing, significant crack healing, reduce or eliminate casting defects, the as-cast structure into a deformed structure, improve the processing performance of the alloy.
(3), hot rolling is usually the use of large ingots, large pressure rolling, not only improve the production efficiency, but also to improve the rolling speed, rolling process to achieve the continuity and automation to create the conditions.
3, cold-rolled plate is hot rolled coil as raw material, at room temperature in the recrystallization temperature below the rolling. The production process because there is no heating, so there is no hot rolling often appear pitting and iron oxide skin defects, the surface quality is good, high finish. And cold-rolled products, high dimensional accuracy, product performance and organization to meet some special requirements, such as electromagnetic performance, deep drawing performance. Cold rolled strip with a wide range of uses, such as automobile manufacturing, electrical products, locomotives and rolling stock, aviation, precision instruments, canned food and so on.
