440C Cov Ntawv Hlau Stainless Hlau

440C Stainless Hlau yog lub siab - cov roj carbon monoxationitic stainless hlau paub, thiab corrosion tsis kam. Nws ua kom cov khoom siv zoo dua thiab cov khoom muaj zog piv rau lwm cov qib hauv 400 Series Stainless Hlau {4} Ua cov cuab yeej, thiab kev phais cov cuab yeej.

Cov Khoom Siv Neeg Kho Tshuab

Kev nyuaj

440C Stainless Hlau Phaj Cov Khoom Taw Qhia kuj yog qhov nyuaj rau hauv nws lub xeev tsis tau siv, ua rau ib qho nyuaj ntawm cov hlau tsis muaj zog. Rau cov ntawv thov xws li txiav cov cuab yeej thiab bearings, cov pom zoo hardness tom qab kev kho cua sov yog HRC 57-59. Nrog kev kho siab tob cryogenic, Hardness tuaj yeem ncav cuag ib puag ncig HRC, lub hardness, thaum tom qab kev txiav txim siab, nws yog qhov loj dua lossis sib npaug nrog 633 HV.

Lub zog

Cov khoom siv mechanies suav nrog kev ntxhov siab sab hauv ntawm 250 n / mm² lub zog ntawm 560 n / mm², elongation (EL) ntawm 18% ntawm 250.

Kev muaj zog

440C cov stainless hlau cov khoom pov thawj muaj zog muaj zog, uas, nrog rau cov khoom siv uas xav tau, xws li kev tsim khoom ntawm cov khoom siab siab.

Fabrication Cov yam ntxwv

Kev sib tsoo cov khoom

Thaum sib tsoo 440c, nws zoo li muaj qib siab ntawm kev nplaum thiab ua kom sov sai sai. Nws raug nquahu kom siv Chrome Corundum lossis microcrystalline colundum log rau kev sib tsoo.

Lwm cov khoom

Corrosion Kuj

440C Stainless hlau muaj muaj zog corrosion tsis kam, ua rau tsim cov pob txheem tsim qauv uas ua haujlwm hauv cov khoom siv oxidatheres tsis muaj lubrication. Nws corrosion resistance yog ntaus nqi rau nws cov ntsiab lus chromium siab. Tsis tas li ntawd, vim nws corrosion tsis kam thiab muaj zog, nws yog siv nyob rau hauv ntau daim teb, nrog rau cov cuab yeej siv tshuaj, thiab marine.

Lub magnetism

440C Stainless hlau sib nqus tau sib nqus, uas yog tus cwj pwm raug ntawm Martensitic Stainless hlau.

1. Riam tsim

440C Stainless hlau feem ntau siv nyob rau hauv kev tsim cov khoom siab -} zoo riam thiab txiab. Nws cov hniav sib xyaw cov hniav tau txais los ntawm 440C lub hardness thiab corrosion tsis kam. Tom qab quenching, 440c ua tiav lub hardness ntau dua 440A hlau, thiab kev kho kom sib sib zog nqus cryogenic feem ntau ua haujlwm hauv cov txheej txheem kev kho cua sov.

2. Kev Raug Mob Raug

Cov hlau no feem ntau siv los tsim cov khoom sib xyaw ua ke uas tsis muaj lub cev tsis muaj zog, ua rau nws qhov ntsuas hluav taws xob tsis ruaj khov

3. Lwm cov ntawv thov

440C Stainless hlau kuj tseem siv nyob rau hauv kev tsim khoom ntawm turbine hniav, lub cev nozzle lub cev, rulers, thiab cutlery (xws li riam thiab txiab). Nws cov ntawv thov txuas ntxiv rau ntau daim teb, suav nrog cov khoom lag luam hlau, cov khoom siv hluav taws xob tsis zoo, nce qib, thiab kev ua tshuab ua tshuab ua tshuab. Ib qho ntxiv, nws yog siv rau hauv cov khoom siv kho mob, cov cuab yeej kho mob, cov ntawv thov cov khoom siv marine, nrog rau kev tsim cov roj pneumatic thiab pwm.

1. Annealing

Lub annealing kub rau 440c stainless hlau yog nruab nrab ntawm 800 - 920℃nrog qeeb txias. Lub resulting microstructure tom qab annealing yog martensitic.

2. Quenching

Quenching yog ua nyob rau ntawm qhov kub thiab txias txij li 1010 - 1070 degree, ua raws li los ntawm roj txias.

3. Tempering

Tempering yog ua nyob rau ntawm qhov kub ntawm 100 - 180℃nrog sai sai txias. Rau cov ntawv thov uas 440C yog siv los ua cov kabmob stainless hlau, nws feem ntau pom zoo kom ua cov haujlwm sib sib zog nqus ua ntej kev ua haujlwm tempering. Qhov kev kho siab tob tob no tuaj yeem txhim kho lub hardness ntawm cov hlau, txhim kho cov hnav tsis kam, thiab nce ruaj ruaj ruaj khov.
