Tseem muaj ntau yam cuam tshuam rau qhov zoo ntawm nickel-based alloy kav
Tseem muaj ntau yam cuam tshuam rau qhov zoo ntawm nickel-raws li cov kav dej alloy. Peb kuj yuav tsum tau kwv yees li kev nkag siab qee cov ntsiab lus hais txog nws qhov kev ua tau zoo. Cia peb tham txog qhov zoo thiab ua tau zoo ntawm cov kav hlau stainless hlau.
Qhov zoo thiab ua tau zoo ntawm stainless hlau kav yog txiav txim raws li kev xav tau. Cov kev xav tau txawv uas xav tau yuav tsum muaj cov ntsiab lus sib txawv. Qhov ntau dua cov ntsiab lus carbon, ntau dua qhov tawv ntawm tus hlau, tab sis qhov tsis zoo nws cov yas thiab tawv. Sulphur yog ib qho kev tsim txom impurity hauv cov hlau. Cov hlau uas muaj zog Sulfur, cov ntsiab lus sulfur muaj zog yog nquag ua rau muaj kev sib tsoo thaum muaj kev kub siab thaum muaj kub, uas feem ntau hu ua kub brittleness. Phosphorus tuaj yeem txo cov plasticity thiab tawv ntawm cov hlau, tshwj xeeb tshaj yog thaum kub tsawg. Qhov xwm txheej no yog hu ua txias brittleness. Nyob rau hauv superior steel, leej faj thiab phosphorus yuav tsum muaj nruj me ntsis tswj tau. Tab sis ntawm qhov tod tes, cov roj carbon steel muaj cov sulfur thiab phosphorus muaj zog, uas tuaj yeem ua kom nws tau yooj yim rau kev txhim kho cov tshuab luam ntawv ntawm cov hlau. Manganese tuaj yeem txhim kho lub zog ntawm cov kav dej chiv, kom muaj zog thiab ntxuav cov kev tsis zoo ntawm cov neeg leej twg ntawm cov hlau. High-alloy steel (High Manganese hlau) nrog cov ntsiab lus muaj zog manganese tau hnav zoo thiab lwm yam khoom siv lub cev. Silicon tuaj yeem txhim kho lub hardness ntawm cov hlau, tab sis cov plastonity thiab cov tawv nqaij muaj tsawg. Cov hlau hluav taws xob muaj qee qhov nyiaj ntawm silicon, uas tuaj yeem txhim kho cov khoom muag muag muag. Sab hauv sab hauv ntawm 304 seamless yeeb nkab yog polishedicically nrog zes thiab linear polishing. Cov cua sov tsis kam ntawm cov yeeb nkab steel hlau yog hais txog kev ua haujlwm ntawm kev tiv thaiv kub, thiab cov roj tsis sib haum ntawm qhov kub, thiab qhov ntawd yog lub zog. Cov cawv ntawm cov pa roj carbon carbon carbon yog ib qho kev tsim tawm thiab ruaj khov Austenite thiab nthuav cov Austenite cheeb tsam hauv Austenitic steel.
