Stainless hlau - Qib 431 (UNS S43100)

Qib 431 stainless hlau yog martensitic, qib kub-kho tau zoo heev corrosion kuj, lub zog torque, siab toughness thiab tensile zog. Tag nrho cov khoom no ua rau lawv zoo tagnrho rau kev siv bolt thiab ncej. Cov hlau no, txawm li cas los xij, tsis tuaj yeem ua haujlwm txias vim lawv lub zog tawm los siab, yog li lawv tsim nyog rau kev ua haujlwm xws li spinning, sib sib zog nqus nqus, khoov lossis txias taub hau.

Fabrication ntawm martensitic steels feem ntau yog ua los ntawm cov txheej txheem uas tso cai rau hardening thiab tempering kho thiab tsis zoo weldability. Cov khoom tiv thaiv corrosion ntawm qib 431 steels qis dua li qib austenitic. Kev ua haujlwm ntawm qib 431 raug txwv los ntawm lawv qhov poob ntawm lub zog ntawm qhov kub thiab txias, vim yog overtempering, thiab poob ntawm ductility ntawm qhov kub tsis zoo.
