SS431
SS431 is a type of stainless steel known for its excellent combination of corrosion resistance, high strength, and heat treatability. It belongs to the martensitic family of stainless steels and is often used in applications requiring high mechanical properties and resistance to corrosion.
SS431 has fair weldability using conventional welding methods such as gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW). Preheating and post-weld heat treatment are often recommended to reduce the risk of cracking. SS431 is valued for its combination of corrosion resistance, high strength, and heat treatability, making it suitable for various demanding applications in industries such as aerospace, marine, and industrial equipment. Proper heat treatment and processing are essential to achieve the desired mechanical properties and minimize magnetic properties for specific applications.
