Carbon is the main element of the steel industry, steel and organizational performance is largely determined by the carbon content in steel and its distribution in the form of carbon in the stainless steel is particularly significant. Carbon in the stainless steel in impact on the organization mainly in two aspects, one of the elements carbon stable austenite, and the extent of the role of large (approximately 30 times the nickel), and partly because the affinity of carbon and chromium is large, and the formation of chromium - series of complex carbides. Therefore, strength and corrosion-resistant candle performance both in terms of the role of carbon in stainless steel is contradictory.
Know the impact of the law, we can proceed from different application requirements, choose a different carbon content of stainless steel.
For example, the most widely used in industry, is the most basic steel - 0Crl3 ~ 4Cr13 five steel standard chromium content is 12 to 14%, that is, the carbon to form chromium carbide and chromium factors taken into account later decision, the purpose is to make the carbon that is combined into chromium carbide and chromium after the solid solution of chromium content not less than 11.7% of the minimum amount of chromium. In this five carbon steel pipe is as different strength and corrosion resistance is also different, 0Cr13 ~ 2Crl3 better corrosion resistance of steel but the intensity is lower than 3Crl3.
