CA40F ASTM A743 Grade（UNS）：J91154 Alloy Family: Martensitic Stainless Steel
CA40F is a kind of martensitic alloy improved by CA40. It is a kind of martensitic stainless steel with low Cr content. It has no rust and corrosion resistance is better than CA40 martensitic stainless steel.
It has good plasticity, toughness and cold formability, and is superior to other martensitic stainless steels with higher Cr content. When the carbon content is controlled very low, the plasticity, toughness and cold formability will be improved significantly.
It is mainly used for manufacturing lining of components and equipment resistant to steam, ammonium bicarbonate mother liquor, hot sulfur-containing petroleum corrosion.
