Stainless steel coil is a specially processed stainless steel material that is widely used in construction, manufacturing, home decoration and other fields. Its production process mainly includes raw material selection, hot rolling processing, cold rolling processing, annealing treatment, pickling treatment and cutting processing.

Stainless steel coil is a specially processed stainless steel material that is widely used in construction, manufacturing, home decoration and other fields. Its production process mainly includes raw material selection, hot rolling processing, cold rolling processing, annealing treatment, pickling treatment and cutting processing.

First of all, in the production process of stainless steel coils, the selection of raw materials is crucial. The raw materials usually used are stainless steel billets that have been smelted, cast, rolled and other processes in steel mills. These billets have the characteristics of high strength, corrosion resistance and high temperature resistance.

Secondly, it goes through the hot rolling process. At this stage, the stainless steel billet is heated to a suitable temperature and then rolled using hot rolling machinery and equipment. Hot rolling can make the stainless steel billet more compact, increase the density and strength of the material, and also improve the surface quality.

Then, cold rolling is performed. Cold rolling is the further processing of hot-rolled stainless steel coils at room temperature. During the cold rolling process, by adjusting the process parameters of the rolling mill, such as the roll structure and roll spacing of the rolling mill, the thickness, width and surface quality of the stainless steel coil can be further improved.

Next is the annealing process. During the hot rolling and cold rolling processes, the structure and properties of stainless steel coils will change due to the influence of stress and strain. Annealing treatment is to heat the stainless steel coil to a certain temperature and keep it warm for a period of time to cause corresponding changes in the internal structure, eliminate stress and strain, and improve the plasticity and toughness of the material.

Then comes the pickling treatment. Pickling is to soak stainless steel coils in an acidic solution to remove oxides and contaminants on the surface and improve the surface quality of the stainless steel coils. During the pickling process, the concentration and temperature of the acid solution need to be controlled to avoid damage to the stainless steel coil.

The last step is the cutting process. According to the user's requirements, stainless steel coils can be cut to length by shearing machinery and coiled by coiling machinery. Cutting processing can process stainless steel coils into products of different sizes and shapes, which can be supplied to users in different fields.

To sum up, the production process of stainless steel coils includes raw material selection, hot rolling processing, cold rolling processing, annealing treatment, pickling treatment and cutting processing. The processing of these links can improve the physical properties and surface quality of stainless steel coils and meet the needs of stainless steel materials in different industries.

Solid solution treatment of stainless steel pipes

The intermediate aging method is heated to (760±15)℃ after solid solution treatment and kept for 90 minutes. Because Cr23C6 carbide precipitates from the austenite, the carbon and alloy element content in the austenitic 904L stainless steel pipe is reduced. , raise the Ms point to 70°C and then cool to room temperature to obtain the martensite + α ferrite + retained austenite structure. The residual austenite will be decomposed after subsequent aging at 510°C.

What are the classifications of carbon steel pipes?

In addition to general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (rolled) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, and stainless steel pipes. Rusty thin-walled steel pipes, special-shaped steel pipes. The outer diameter of hot-rolled seamless steel pipes is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipes can be up to 6mm, and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipes can be up to 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.
