Is stainless steel coil the same as stainless steel strip?
At present, stainless steel products can be seen everywhere, including stainless steel stairs, stainless steel decoration and so on. Stainless steel products include our common stainless steel plates, stainless steel tubes, stainless steel rods, etc. In addition, are stainless steel coils and stainless steel strips the same as coils?
First of all, stainless steel coil and stainless steel strip are not one product.
The width of stainless steel strip is generally not more than 500mm, which can be used to process into small diameter stainless steel welded steel pipe; while the width of stainless steel coil is relatively large, and it is generally processed into medium and large diameter stainless steel welded steel pipe.
The stainless steel strip is simply an extension of the ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.
There are many types of stainless steel belts, mainly: 201 stainless steel belt, 202 stainless steel belt, 304 stainless steel belt, 301 stainless steel belt, 302 stainless steel belt, 303 stainless steel belt, 316 stainless steel belt, J4 stainless steel belt, 309S stainless steel belt, 316L stainless steel belt, 317L Stainless steel belt, 310S stainless steel belt, 430 stainless steel iron belt, etc.
Like other materials, the physical properties of stainless steel strip mainly include the following three aspects: thermodynamic properties such as melting point, specific heat capacity, thermal conductivity and linear expansion coefficient, and electromagnetic properties such as resistivity, electrical conductivity and magnetic permeability. These properties are generally considered to be inherent properties of stainless steel materials, but are also affected by factors such as temperature, degree of processing and magnetic field strength. Generally speaking, stainless steel has lower thermal conductivity and higher resistance than pure iron, and the properties such as linear expansion coefficient and magnetic permeability vary according to the crystal structure of stainless steel itself.
Stainless steel strips have many uses, mainly used in automobiles, electrical appliances, electronic components, tubes, needles, etc. At present, precision strips are used for stamping parts, mainly for mobile phones, computers, printers, etc., as well as needle tubes, fiber optic catheters Wait.
However, stainless steel strip is most widely used in cold rolled strip, which is another subsidiary industrial steel strip product formed after processing by cold rolling mill at room temperature with stainless steel strip as the basic raw material. Cold-rolled strips have excellent characteristics such as smooth surface, smooth surface, high dimensional accuracy and good mechanical properties, and are often processed into coils and coated steel sheets. In industrial manufacturing such as tractors and automobiles, cold-rolled strips are widely used.
