Stainless hlau 17-7PH
Nyiv SUS631 (17-7PH) yog dispersion hardening stainless hlau, muaj zog, siab hardness, qaug zog kuj, zoo corrosion kuj, thiab malleability, raws li zoo raws li ntsib kub thiab deformation me ntsis, qhov no steel kev ua tau zoo, tshwj xeeb tshaj yog rau aerospace teb, qhov tshwj xeeb alloy no kuj tau yoog rau lwm qhov chaw nrog lub zog siab, kev tiv thaiv corrosion. Thaum kub txog 316 degree, lub caij nplooj ntoos hlav kev ua haujlwm tseem zoo.
Cov khoom siv kho mob rau lub koom haum tsis ruaj khov austenite, zoo yas toughness, thiab cov txheej txheem, tom qab kev hloov kho, kom cov austenite nag lossis daus carbide tos rau kev hloov pauv, thiab tom qab ntawd tom qab cov txheej txheem martensitic transformation, feem ntau ntawm lub koom haum yog hloov mus rau hauv lub toughness ntawm qis. carbon tempered martensite, lub xeev no rau kev siv lub xeev steel, muaj zoo mechanical zog ntawm nruab nrab kub. Corrosion kuj zoo dua li cov martensitic stainless hlau.
17-7PH stainless hlau muaj nyob rau hauv peb lub xeev - RH 950 thiab TH 1050, uas tuaj yeem ua rau cov qib siab muaj zog los ntawm kev kho cua sov yooj yim, thaum CH 900 yuav tsum tau siv rau qhov chaw muaj zog uas tsis tas yuav muaj cov khoom zoo heev thiab ua haujlwm tau zoo.
