0Cr13 stainless steel

0Cr13 is the one with the lowest Cr content in ferritic stainless steel.

0Cr13 has stainless, and its corrosion resistance is better than 1Cr13, 2Cr13, 3Cr13, 4Cr13 martensitic stainless steel with high carbon content. It has good plasticity, toughness and cold formability, and is superior to other martensitic 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 for the manufacture of water vapor, ammonium bicarbonate mother liquor, hot sulfur-containing petroleum corrosion parts and equipment linings.

The American grade corresponding to this steel grade is 405, the specific gravity is 7.75g/cm3, and 0Cr13 is the one with the lowest Cr content in ferritic stainless steel.

0Cr13 mechanical properties:
Tensile strength σb (MPa): quenching and tempering, ≥490
Conditional yield strength σ0.2 (MPa): quenching and tempering, ≥345
Elongation δ5 (%): Quenching and tempering, ≥24
Area shrinkage ψ (%): quenching and tempering, ≥60
Hardness: Annealed,≤183HB
