431 Stainless Steel Bar Material has excellent corrosion resistance to a wide range of corrosive media. It has some resistance to salt water in cold southern waters, but it is unlikely to be successful in warm tropical waters. Overall, the corrosion resistance of 431 Round Bar Material is about the same as or slightly less than that of 304 Grade Material. It performs best when it has a smooth surface in the hardened and tempered condition.
Resists scaling in intermittent service to 925°C and in continuous service to 870°C, but is generallynot recommended for use in temperatures above the relevant tempering temperature, because ofreduction in mechanical properties.
Full anneal - not practical for this grade - it hardens even when cooled slowly. Process Anneal -heat to 620-660°C and air cool.
Hardened by heating to 980-1065°C, holding for about 1/2 hour then quenching in air or oil.Pre-heating at 760-790°C may be useful for complex parts or those already hardened. Temper tosuit mechanical requirements, at temperatures as indicated in the accompanying table.
The tempering range 425-600°C should be avoided due to reduced impact toughness, althoughthe effect is less marked than in most other martensitic grades.
Welding is difficult due to the risk of cracking. A pre-heat of 200-300°C is recommended priorto welding. Grade 410 filler rod can be used, but Grades 308L, 309 or 310 will provide moreductile welds, so long as matching properties are not required. Post-weld heat treat at 650°C.
In the annealed condition this grade is relatively easily machined, but if hardened to above 30HRCmachining becomes more difficult. A Ugima Improved Machinability version of Grade 431 offers asignificant improvement in achievable machining speeds and tool life.
