Cold-rolled stainless steel strip, also known as stainless steel cold-rolled strip or stainless steel cold-rolled Banding, is a kind of hot-rolled stainless steel strip as billet, after rolling at room temperature under the recrystallization temperature. Compared with the hot-rolled stainless steel strip, it has the characteristics of high dimensional accuracy, low surface roughness, good surface quality, smoothness and high strength. Therefore, the thin cold-rolled stainless steel strip can be used to replace the thick hot-rolled strip, and it also has various superior mechanical properties to save steel consumption.
There are many factors affecting the price of cold rolled stainless steel strip, such as specifications, brands, regions and so on. The price of cold-rolled stainless steel strip in Foshan is generally around 1000 yuan / ton, while the price in Tianjin is more expensive, about 13000 yuan / ton. In Shanghai, the price fluctuates greatly. The price of cold-rolled stainless steel strip is 20000 yuan / ton, and the price of cheap stainless steel strip is 10000 yuan / ton.
The thickness specifications of cold rolled stainless steel strip are between 0.01 mm and 3.0 mm, the width specifications are between 2.0 mm and 1250 mm, the hardness level is between 145 HV and 650 HV, and the surface states are as follows: 2B, BA, 8K, 6K, mirror, etc.
Cold rolled stainless steel strips can be divided into soft and hard ones. Cold-rolled stainless steel strip soft materials are mainly used in electrical appliances, stainless steel kitchenware, hardware products, ground springs, sanitary ware, chemical, petroleum, pipe making, cable wrapping, medical treatment, bending and flanging, mechanical equipment manufacturing, construction and other related industries. Cold-rolled stainless steel strip is mainly used in electronics, electrical appliances, computers, high-tech parts, adjusting gaskets, metal stamping parts, such as spring springs and other stainless steel industries (1/4H, 1/2H, 3/4H, H all hard).
The Stainless Steel Strip is the same as other materials, and the physical function mainly includes the following aspects
the thermodynamic functions such as melting point, specific heat capacity, thermal conductivity and linear expansion coefficient, such as electrical and magnetic functions such as resistivity, conductivity and permeability, and Young's elastic modulus, rigidity coefficient and other mechanical functions. These functions are often considered to be inherent in stainless steel data, but they are also affected by temperature, processing degree and magnetic field strength. Usually the stainless steel and iron relatively low thermal conductivity, high electrical resistance, and thermal expansion coefficient and permeability function depends on the crystal structure of the stainless steel.
The physical functions of martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, hardened stainless steel and double phase stainless steel. Such as density, melting point, specific heat capacity, thermal conductivity, linear expansion coefficient, resistivity, magnetic permeability and longitudinal elastic coefficient and other parameters.
Structural classification of Stainless Steel Strip
The Stainless Steel Strip has become a necessary part of the people's life. The Stainless Steel Strip is related to people's quality of life and promote the national finance. So what is the stainless steel belt in the end?
Structural steel strip
With heat treatment (annealing, normalizing, normalizing after tempering, high temperature tempering) state delivery.
The steel strip can be delivered without heat treatment under the condition that the performance meets the standard requirements. Ordinary drawing grade steel strip is allowed to be delivered without heat treatment.
The cold rolled steel strip is delivered by heat treatment (annealing, normalizing, normalizing after tempering) and should be delivered.
Usage: widely used in the automobile industry, the aviation industry and other departments, with a large amount of use.
