Overview
CF10SMnN is an austenitic stainless steel casting alloy defined by ASTM A351/A351M, designed for pressure-containing applications such as valves, flanges, and fittings. It features enhanced machinability and strength due to its elevated manganese and nitrogen content. The nitrogen improves yield strength and corrosion resistance, while the high manganese content helps maintain austenite stability and supports the alloy's non-magnetic character. This alloy is particularly suitable for applications where a combination of corrosion resistance, higher mechanical strength, and improved machinability is desired. Common industries include food processing and chemical equipment.
