Industrial stainless steel coil: heat exchanger, boiler, petroleum, chemical, chemical fertilizer, chemical fibre, pharmaceutical, nuclear power, etc. Fluid stainless steel coil: beverage, beer, milk, water supply system, medical equipment, etc.
Carbon is one of the main elements of industrial steel. The properties and microstructure of steel are largely determined by the content and distribution of carbon in the steel, especially in stainless steel coil. The influence of carbon on the structure of stainless steel coil is mainly manifested in two aspects. On the one hand,
Carbon is an element of stable austenite, and the degree of action is very large (about 30 times that of nickel). On the other hand, due to the great affinity between carbon and chromium, it forms a series of complex carbides with chromium.
In terms of strength and corrosion resistance, the role of carbon in stainless steel coils is contradictory. Knowing the law of this effect, we can choose stainless steel coil with different carbon content according to different requirements.
The most widely used in industry, for example, is at the very least cr13 stainless steel coil - 0-4 cr13 these five steel grade standard chrome gauge as 12-14%, is to put the carbon and chromium after the formation of chromium carbide factors into consideration, the purpose is to make the carbon and chromium as chromium carbide, the chromium content of the solid solution is not less than 11. A minimum of 7% chromium content. In terms of the five steel grades because the carbon content, strength and corrosion resistance are also differentiated, 0 cr13-2 cr13 steel has good corrosion resistance strength of fewer than 3 cr13 and 4 cr13 steel, multi-purpose, in manufacturing structure parts, after two steel grade due to high carbon.
Advantages of Stainless Steel Coils-
- High strength can also be obtained, which is useful in the production of springs, knives, and other parts that require high strength and abrasion resistance. For example, the carbon content of 18-8 cr-ni stainless steel coil can be reduced to less than 0.03 percent in order to overcome intercrystalline corrosion.
- To prevent the formation of chromium carbide, an element (titanium or niobium) with a higher affinity for chromium and carbon can be added. As the high hardness and wear resistance become increasingly important, we can increase the carbon content of steel while also increasing the chromium content.
- Both meet the requirements for hardness and wear resistance, as well as corrosion resistance, by focusing on two or more aspects of the industry, such as bearings, measuring tools, and cutting tools made of stainless steel coils 9 cr18 and 9 cr17movco steel, with carbon content ranging from 0.85 to 0.95 per cent, and chromium content correspondingly improved, so they still meet the corrosion resistance requirements.
