0Cr13、Z6C13、Z8C12、Z8C13FF

0Cr13 is the one with the lowest Cr content in ferritic stainless steel. It is stainless and has better corrosion resistance than 1Cr13, 2Cr13, 3Cr13, 4Cr13 martensitic stainless steel with high carbon content. It has good plasticity, toughness and cold formability, and is better than other ferritic stainless steels with higher Cr content. When the C content in 0Cr13 steel is controlled very low, its plasticity, especially toughness, and cold formability will be significantly improved. 0Cr13 steel is mainly used to manufacture water vapor, ammonium bicarbonate mother liquor, hot sulfur-containing petroleum corrosion parts and equipment linings. The corresponding American standard grade for this steel grade is 405, and the specific gravity is 7.75g / cm30Cr13 is the lowest Cr content in ferritic stainless steel.
