(4) Tsis txhob hu rau cov hlau uas tsis tshua muaj melting point xws li sulfur, phosphorus, thiab txhuas thaum kho cua sov. Txwv tsis pub, cov khoom ntawm cov alloy yuav raug puas tsuaj. Ua tib zoo saib xyuas cov av, xws li kos cov xim, qhov kub thiab txias qhia cov xim, xim crayons, lubricating roj, roj, thiab lwm yam.
(5) Qhov qis ntawm cov sulfur cov ntsiab lus ntawm cov roj, qhov zoo dua. Cov ntsiab lus sulfur ntawm tianranqi yuav tsum tsawg dua 0.1%, thiab cov ntsiab lus sulfur ntawm cov roj hnyav yuav tsum tsawg dua 0.5%.
(6) Lub qhov cub cua sov cua sov yog qhov zoo dua nruab nrab rau micro-oxidizing. Lub tshuab hluav taws xob yuav tsum tiv thaiv kom tsis txhob hloov pauv ntawm oxidation thiab txo qis. Cov nplaim hluav taws kub tsis tuaj yeem hlawv ncaj qha rau ntawm qhov chaw ua haujlwm.
Hastelloy C276 Cua sov: Cov khoom ua haujlwm yuav tsum tau ceev kom huv si thiab tsis muaj kab mob ua ntej thiab thaum kho cua sov. Tsis txhob hu rau cov hlau uas tsis tshua muaj melting point xws li sulfur, phosphorus, thiab txhuas thaum kho cua sov. Txwv tsis pub Nicrofer6616hMo alloy yuav nkig. Ua tib zoo saib xyuas cov av kom huv si, xws li kos cov xim, qhov kub thiab txias qhia cov xim, crayons, lubricating roj, roj, thiab lwm yam. Qhov qis dua cov sulfur cov ntsiab lus hauv cov roj, qhov zoo dua; cov ntsiab lus sulfur hauv Tianranqi yuav tsum tsawg dua 0.1%, thiab cov ntsiab lus sulfur hauv cov roj hnyav yuav tsum tsawg dua 0.5%. Lub tshuab hluav taws xob cua sov yog qhov kev xaiv zoo dua vim tias lub tshuab hluav taws xob muaj peev xwm tswj tau qhov kub thiab txias ntawm lub cub tawg thiab lub cub tawg kom huv si. Yog tias lub qhov cub hluav taws xob muaj roj ntshiab txaus, nws kuj yog ib qho kev xaiv. Lub tshuab hluav taws xob ntawm lub qhov cub cua sov yog qhov zoo dua nruab nrab kom txo qis me ntsis.

(2) Txoj kev txias yog dej quenching. Cov khoom siv nrog lub thickness tsawg dua 1.5 hli kuj tuaj yeem siv rau cua txias sai. Yog siv cua txias, nws yuav tsum tau txias los ntawm 1000 degree mus rau 600 degree hauv 2 feeb.
(3) Thaum lub sij hawm kev kho cua sov, lub workpiece yuav tsum huv si.
Hastelloy C276 alloy nto tshem tawm:
(1) Cov txheej txheej oxide saum npoo thiab vuam slag ncig Hastelloy C276 muaj zog adhesion dua stainless hlau. Nws raug nquahu kom siv cov khoom siv zoo-grain abrasive siv los yog nplua-grain sib tsoo log rau kev sib tsoo.
(2) Ua ntej pickling nrog HNO3 / HF tov kua qaub, oxide zaj duab xis yuav tsum tau sandblasted los yog polished. Machining ntawm Hastelloy C276 alloy: Vim nws rhiab heev rau kev ua hauj lwm hardening, nws raug nquahu kom siv cov txiav ceev thiab hnyav txiav cov cuab yeej rau machining kom nws yooj yim rau tshuab.
