Insimbi Engagqwali - Ibanga 431 (UNS S43100)

Izinsimbi ze-Stainless Grade 431 zingama-martensitic, amamaki aphathwa ngokushisa anokumelana nokugqwala okuhle kakhulu, amandla etorque, ukuqina okuphezulu kanye nezakhiwo eziqinile. Zonke lezi zakhiwo zizenza zilungele ukusetshenziswa kwe-bolt ne-shaft. Lezi zinsimbi, nokho, azikwazi ukusebenza ngokubandayo ngenxa yamandla azo esivuno esiphezulu, yingakho zilungele ukusebenza njengokuphotha, ukudweba okujulile, ukugoba noma isihloko esibandayo.

Ukwenziwa kwezinsimbi ze-martensitic ngokuvamile kwenziwa kusetshenziswa amasu avumela ukuqina nokwelashwa kokuthambisa kanye nokushisela okubi. Izakhiwo zokumelana nokugqwala kwezinsimbi zebanga lama-431 ziphansi kunalezo zamamaki e-austenitic. Ukusebenza kwebanga lama-431 kunqunyelwe ukuphelelwa amandla emazingeni okushisa aphezulu, ngenxa yokufutheka ngokweqile, kanye nokulahlekelwa kwe-ductility emazingeni okushisa angemahle.
