Alloy 410S (UNS S41008) yog cov pa roj carbon tsawg, tsis-hardening hloov kho ntawm Alloy 410 (UNS S41000) lub hom phiaj dav dav 12% chromium martensitic stainless hlau. Cov pa roj carbon tsawg thiab cov hlau me me ntxiv txo qis austenite tsim ntawm qhov kub thiab txias uas txwv tsis pub cov alloys muaj peev xwm ua kom tawv. 410S tseem mos thiab ductile txawm tias sai sai txias los ntawm qhov kub thiab txias. Cov yam ntxwv uas tsis yog-hardening no pab tiv thaiv kev tawg thaum lub alloy raug kub los yog welded. 410S yog kiag li ferritic nyob rau hauv lub annealed mob. Nws pom zoo corrosion kuj zoo ib yam li 410 thiab zoo oxidation kuj.

Corrosion Resistance
Lub corrosion kuj ntawm Sandmeyer Steel 410S stainless hlau zoo ib yam li hom 410. Nws resists corrosion nyob rau hauv atmospheric tej yam kev mob, dej tshiab, me me organic thiab mineral acids, alkalis thiab ib co tshuaj. Nws raug cov tshuaj chlorides hauv kev ua ub ua no txhua hnub (xws li, kev npaj zaub mov, kev ua kis las, thiab lwm yam) feem ntau txaus siab thaum kev ntxuav kom zoo tom qab siv tau.

Cov ntaub ntawv Fabrication
Kev kho cua sov
Lub alloy tsis tuaj yeem hardened los ntawm kev kho cua sov. Nws yog annealed nyob rau hauv 1600 - 1650 degree F (871 - 899 degree) ntau yam thiab ces cua txias kom txo tau txias ua hauj lwm stresses. 410S yuav tsum tsis txhob raug kub ntawm 2000 degree F (1093 degree) los yog siab dua vim embrittlement. Yog tias cov nplej loj dhau lawm tom qab muab cov khoom ua haujlwm txias me ntsis, qhov kub ntawm qhov sib xyaw yuav tsum tau txo kom tsawg li ntawm 1200 - 1350 degree F (649 - 732 degree).
Kev npaj nto
Rau qhov siab tshaj plaws corrosion tsis kam rau cov tshuaj ib puag ncig, nws yog ib qho tseem ceeb uas 410S nto tsis muaj cov cua sov los yog oxide tsim thaum lub sij hawm annealing los yog kub ua hauj lwm. Txhua qhov chaw yuav tsum yog hauv av los yog polished kom tshem tawm cov kab ntawm oxide thiab decarburization nto. Tom qab ntawd cov khoom yuav tsum tau muab tso rau hauv qhov dej sov ntawm 10-20% nitric acid tom qab dej yaug kom tshem tawm cov hlau seem.
Tshuab dhos
Alloy 410S yuav tsum tau machined nyob rau hauv lub annealed mob siv nto ceev ntawm 60 mus rau 80 ko taw (18.3 - 24.4 m) ib feeb.
Vuam
Rau qhov siab tshaj plaws corrosion tsis kam rau cov tshuaj ib puag ncig, nws yog ib qho tseem ceeb uas 410S nto tsis muaj cov cua sov los yog oxide tsim thaum lub sij hawm annealing los yog kub ua hauj lwm. Txhua qhov chaw yuav tsum yog hauv av los yog polished kom tshem tawm cov kab ntawm oxide thiab decarburization nto. Cov khoom yuav tsum yog 410S feem ntau suav hais tias yog weldable los ntawm kev sib xyaw ua ke thiab kev ua haujlwm. Kev txiav txim siab tshwj xeeb yuav tsum tau muab rau kom tsis txhob nkig weld fractures thaum lub sij hawm tsim los ntawm kev txo qis kev tsis sib xws, tswj cov khoom siv hluav taws xob tsawg thiab qee zaus ua kom sov qhov me me ua ntej tsim. 410S feem ntau suav hais tias muaj qhov tsis zoo me ntsis weldability tshaj qhov feem ntau ferritic stainless hlau qib 409. Qhov sib txawv loj tuaj yeem raug ntaus nqi rau cov hlau ntxiv los tswj cov tawv tawv uas ua rau xav tau cov cua kub ntau dua kom tau nkag mus thaum lub sij hawm arc vuam. Thaum xav tau ib qho kev sib txuas, AWS E/ER 309L lossis 430 muab cov khoom siv feem ntau tau teev tseg.immersed hauv cov tshuaj sov ntawm 10-20% nitric acid ua raws li cov dej yaug kom tshem tawm cov hlau seem.
