Cold-rolled Steel Production Accounts For About 30% Of Steel Production
Cold-rolled steel is a kind of steel: cold-rolled steel is produced through cold-rolled steel, cold-rolled steel is relatively poor for stainless steel welding performance, Cold Rolled Steel the surface is relatively brittle, hard, not suitable for processing, in general, to the cold-rolled steel Customer requirements before the first annealing, pickling and surface smoothing and other steps.
Cold-rolled steel: It's high strength, but toughness, poor weldability, relatively hard, brittle, bright surface.
Cold-rolled steel and stainless steel thickness difference is quite large, the common cold-rolled steel maximum thickness is 8mm, stainless steel is not limited to the thickness of the provisions of the cold-rolled steel is mainly through the hot-rolled coil as raw material, Cold Rolled Steel each roll can be 13.5 tons, while the stainless steel raw materials are not limited to steel, as well as chromium, molybdenum and other categories belong to the metal material.
Summary: Cold-rolled steel is a kind of steel, plainly cold-rolled steel is cold-rolled steel; stainless steel is a class of steel, this category is divided into many kinds, such as austenitic stainless steel, ferritic stainless steel; Cold-rolled steel is a targeted purchase, a cold-rolled steel, stainless steel is required according to their own needs to buy different materials of stainless steel.
The so-called cold-rolled steel is actually the kind of relatively thin, rectangular plate-type steel, they generally have a thickness of 0.1-3mm range, width and more in the range of 100-2000mm, Cold Rolled Steel while the length is generally longer. From the production process point of view, cold-rolled steel is cold rolled at room temperature from the finished cold-rolled steel products are generally roll package. Cold-rolled steel is also a number of materials and models, but the general cold-rolled steel will be marked steel grades, Cold Rolled Steel through the grades we can know their material and specifications.
Cold-rolled steel is widely used in various types of manufacturing as it has excellent surface smoothness, high dimensional accuracy and good mechanical properties. Cold Rolled Steel It is also used as an important raw material for the building materials industry. At present, in some industrially developed countries, the output of cold rolled steel accounts for about 30% of the total steel output
Cold-rolled steel can be divided into many kinds according to the type of steel and specifications, different types of cold-rolled steel will have some specific uses, but generally speaking, Cold Rolled Steel cold-rolled steel is mainly used in automobile, shipbuilding, electric power, coal, light industry , Household appliances, hardware and other industries. For example, cold rolled steel grades SPCC, Q195 and Q235-B are mainly used in construction machinery, transportation machinery, construction machinery, hoisting machinery, Cold Rolled Steel agricultural machinery and light industry and civil industries General structure and stamping parts, for another example, ordinary cold-rolled strip (GB716-83) for the manufacture of bicycles, sewing machines, agricultural machinery and other accessories and hardware products.
The specific purpose of cold-rolled steel is not clear in a few words, a cold-rolled steel in the end what kind of specific uses is the steel, material, specifications, performance Cold Rolled Steel and other aspects of the decision, and the same cold The specific purpose of rolling steel may also be a number of aspects. We need to make better use of cold-rolled steel, you must first fully understand the different varieties of cold-rolled steel.
