440 Cov Hlau Stainless

Feem ntau hu ua "rab chais hlau" vim nws nquag siv rau kev siv cov chais thiab txiav, qib 440 stainless hlau muab lub zog muaj zog thiab tiv taus corrosion. Tsis tshua muaj neeg muaj peev xwm, nws tau siv ntau hauv kev lag luam los tsim cov khoom lag luam tshwj xeeb, kev lag luam me me thiab muaj nyob hauv ntau hom: 440A, 440B, 440C, thiab 440F.

Cov Kev Siv Ntau

Dhau li yog siv rau kev txiav thiab razorblades, 440 steel hlau kuj tseem siv rau cov ntawv thov me me xws li kev kho hniav thiab kho twj paj. Nws lub tshav kub siab thiab kev txhim kho corrosion ua rau nws zoo tagnrho rau qhov chaw cav xws li dov bearings thiab lub rooj zaum valve, thiab nrog superior hardness thiab puas kuj, nws yog qhov tshwj xeeb zoo tsim rau kev ua tau zoo precision piv pins thiab chais.

Machinability thiab Tsim kom muaj

Los ntawm kev siv kev kho cua sov thiab ua kom tob tob, qib qib 440 stainless hlau tuaj yeem ua tau ob qho tib si hauv thiab tsis khov. Nyob rau hauv nws daim ntawv annealed, cov khoom siv no muaj qhov ua tau zoo machinability, tab sis nws cov pa roj carbon siab cov ntsiab lus - thiab, yog li ntawd, nws lub zog siab - tuaj yeem ua rau nws nyuaj rau kev ua haujlwm nrog. Vim tias nws cov ntsiab lus leej faj siab ua rau nws yooj yim tshuab, hom 440F yog qhov zoo rau cov ntawv thov uas yuav tsum tau siv lub tshuab ntau ntxiv.

Tshuaj lom neeg muaj pes tsawg leeg

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm ntau hom 440 stainless hlau muaj raws li nram no, nrog cov pa roj carbon ntsiab lus yog qhov sib txawv loj:

440A Stainless Hlau

Chromium (Cr) - 16-18%

Manganese (Mn) - 1%

Silicon (Si) - 1%

Molybdenum (Mo) - 0.75%

Phosphorus (P) - 0.04%

Cov Sulphur (S) - 0.03%

Cov pa roj carbon (C) - 0.6-0.75%

440B Stainless Hlau

Cov pa roj carbon (C) - 0.75-0.95%

440C thiab 440F Stainless Hlau

Cov pa roj carbon (C) - 0.95-1.20%

Cov Khoom Tseem Ceeb ntawm 440 Cov Hlau Stainless

Kev tiv thaiv xeb - txhua hom qib 440 stainless hlau muaj qhov zoo corrosion. Yog li ntawv, qib 440 yog qhov zoo rau kev siv rau hauv cov huab cua, ntsuas dhau, thiab tawv.

Thaum tshav kub kub tsis kam - Qeb 440 stainless hlau muaj qhov ua tau zoo rau kev tiv thaiv tshav kub thiab yuav tsum tsis txhob siv cov kub hauv qab no qhov ntsuas kub tsis zoo; tshaj qhov npau taws tuaj yeem ua rau poob ntawm cov cuab yeej.

Kev kho cua sov - Cov khoom siv no muaj ntau yam tuaj yeem kho tau li ntawm 850-900 ° C ua ntej tso cua sov kom txias li ntawm 600 ° C thiab cua txias. Nws kuj tseem tuaj yeem raug muab rhaub ntawm 1010-1065 ° C ces quenched hauv huab cua lossis roj rau ua kom tawv.

Weldability - Thaum vuam, qib 440 stainless hlau yog preheated ntawm 250 ° C, tom qab ntawd los ntawm daim ntawv qhia txog qhov tseem ceeb.

Kev muaj peev xwm - 440 stainless hlau tuaj yeem yooj yim machined hauv annealed lub xeev.

Muab piv rau hom ntawm 440 Stainless Hlau

Thaum txiav txim siab rau cov khoom siv rau koj qhov project, nws yog qhov tseem ceeb kom muaj kev nkag siab zoo ntawm cov khoom sib txawv 440 stainless hlau thiab lawv cov txiaj ntsig thiab cov yam ntxwv. Thaum sib koom ua ob peb yam khoom yooj yim, raws li tau tham saum toj no, 440 steel hlau kuj tseem txawv ntawm ntau txoj hauv kev.

Stainless Hlau 440A

High-carbon martensitic steel

Kev tiv thaiv corrosion tuab

Muaj peev xwm zoo tshaj los tswj hwm kev tawv

Zoo heev hnav tsis kam

Tsis zoo rau kev siv high-temperature

Stainless Hlau 440B

High-carbon martensitic steel

Muaj peev xwm zoo tshaj los tswj hwm kev tawv

Tshuab tau zoo heev

Tsis zoo rau lub vuam tsoo, zoo li nws nyhav rau cov cua ua kom tawv

Stainless Hlau 440C

High-carbon martensitic steel

Lub zog siab

Kev tiv thaiv corrosion tsawg (zoo ib yam li cov ntawm 304)

Zoo coj kuj

Cov yam ntxwv hardness zoo

Muaj peev xwm ua tau lub zog siab tshaj plaws tom qab kev kho cua sov piv rau lwm cov alloys stainless

Tsis yog qhov zoo rau kev siv rau hauv cov ntawv thov nrog qhov kub siab dua cov huab cua sov vim qhov ua rau cov khoom tsis pom

Stainless Hlau 440F

Cov ntsiab lus carbon ntau; tib yam li 440C

Siab hardness zog

Superior corrosion tsis kam

Tso cai rau kev kho cua sov thiab kev ua kom lub tshuab pub dawb

Qhov tsim nyog rau siv nyob rau hauv cov ntawv thov yuav tsum tau muaj qhov siab tawv, tsis-muaj qhov ncauj, thiab tsis ua khoom

Tsis zoo rau cov ntawv thov cuam tshuam nrog cov roj lossis kua hauv qab lub siab
