Type 431 is a hardenable martensitic stainless steel alloy which combines high tensile strength and torsional strength. The material is well suited to shaft manufacture due to these characteristics.
FOR MARINE APPLICATIONS
The alloy is intended for use in applications requiring good strength and toughness combined with reasonable corrosion resistance. As the alloy offers considerable resistance to saltwater corrosion, it is used widely in marine equipment and systems. Type 431 is easily machined in the annealed state, but welding is difficult due to cracking, and it is recommended that the material is preheated to improve welding performance.
SUITABILITY
Type 431 stainless steel is a heat treatable martensitic stainless - the alloy offers high tension and torsional strength and is well suited in the manufacture of shafts. However, welding is poor, and the material cannot be easily cold worked. The alloy is utilised in a number of market sectors with typical uses including laboratory equipment, pumps, shafts and propellers.
