Khoom siv

Qhov ceev: 7.7g / cm³; tensile zog: 590MPa; yield zog: 245MPa; elongation: 15%; hardness HBW: 269; quenching thiab tempering hardness: 55HRC.

Mechanical cwj pwm

1.4112 yog lub siab carbon martensitic stainless hlau. Nws cov khoom siv kho tshuab feem ntau suav nrog lub zog, hardness, toughness, thiab lwm yam. Vim nws cov ntsiab lus carbon thiab chromium siab, hom steel no muaj lub zog siab thiab hardness thiab tuaj yeem tiv taus siab dua thiab hnav. Nyob rau tib lub sij hawm, vim nws zoo toughness, hom steel no tsis yooj yim rau embrittle thiab yuav siv tau nyob rau hauv ntau complex ib puag ncig. Tiv thaiv corrosion los ntawm qhov chaw me me, dej vapor, ammonia, ntau cov khoom siv roj av thiab cov khoom siv organic, thiab ntau yam tsis muaj zog acidic ib puag ncig. Lub annealing kub yog tsawg heev, thiab hardness tom qab quenching yog siab. Lub hardness feem ntau ncav cuag HRC56-58. Nws muaj zoo corrosion kuj (sib nqus) thiab muaj zog toughness.

Cov chaw thov

Vim tias 1.4112 stainless hlau muaj kev tiv thaiv zoo heev thiab cov khoom siv kho tshuab, nws yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, marine engineering, tsheb, zaub mov thiab lwm yam kev lag luam. Nyob rau hauv cov roj av thiab tshuaj industries, vim nws zoo heev corrosion kuj, nws yog siv los tsim reactors, pipelines thiab lwm yam khoom siv. Hauv kev lag luam marine engineering, nws yog siv los tsim cov khoom tseem ceeb ntawm cov nkoj thiab offshore platforms. Hauv kev lag luam tsheb, nws yog siv los tsim cov khoom xws li cov tshuab tso pa thiab cov fasteners. Hauv cov zaub mov, nws yog siv los tsim cov khoom siv hauv chav ua noj thiab cov khoom siv ua zaub mov vim nws cov khoom tu cev zoo.

Kev ua tau zoo

Cov txheej txheem ntawm 1.4112 stainless hlau feem ntau suav nrog vuam, kev kho cua sov thiab kev ua haujlwm. Hom hlau no muaj kev ua haujlwm zoo vuam thiab tuaj yeem welded siv ntau txoj kev vuam. Kev kho cua sov tuaj yeem txhim kho nws cov khoom siv dag zog thiab kev tiv thaiv corrosion, tab sis yuav tsum tau saib xyuas kom tsis txhob tawg lossis deformation los ntawm overheating lossis overcooling. Nws muaj kev ua haujlwm zoo thiab tuaj yeem siv rau kev xa, milling, drilling, tapping thiab lwm yam kev ua haujlwm. Nws qhov tsis zoo yog tias nws nplaum thiab ua kom sov sai, tab sis nws yooj yim dua rau xuab zeb dua li cov pa roj carbon steel thiab yooj yim dua rau txiav nrog tes saw.
