Puas yog nws kim los kho lub bolt tawg ntawm lub cua turbine ntauwd? Sim A4-80 qib stainless hlau studs

Hauv kev lag luam cua fais fab, kev ntseeg siab ntawm ntauwd bolts ncaj qha cuam tshuam rau kev ua haujlwm nyab xeeb thiab kev saib xyuas tus nqi ntawm chav tsev. Cov pa roj carbon monoxide lossis cov hlau tsis zoo tib yam yog qhov ua rau qaug zog tawg, corrosion thiab loosening nyob rau hauv lub sij hawm ntev cua loads thiab vibration ib puag ncig, ua rau tsis tu ncua kev kho thiab lub zog tsim poob. A4-80 qib stainless hlau studs tau dhau los ua cov kev daws teeb meem zoo tshaj plaws rau kev txhim kho kev ntseeg siab hauv kev lag luam cua zog vim lawv cov khoom zoo heev thiab kev tiv thaiv corrosion.

Hom tsis ua haujlwm ntawm cov cua fais fab bolts

1. Kev qaug zog tawg: Lub pej thuam raug hloov pauv thaum lub sijhawm ua haujlwm, thiab cov bolts tsim microcracks thiab nthuav dav hauv kev ntxhov siab.

2. Kev tsis ua haujlwm xoob: kev vibration ua rau preload mus rau lwj, thiab micro-motion hnav tshwm sim ntawm qhov chaw txuas

3. Kev ntxhov siab corrosion: ntsev tsuag ib puag ncig ntawm ntug hiav txwv cua ua liaj ua teb ua kom tawg pib

4. Hydrogen embrittlement txaus ntshai: Kev kho cua sov tsis zoo yuav ua rau ncua kev puas tsuaj.

Technical zoo ntawm A4-80 qib stainless hlau studs

1. Ultra-siab zog: Tsawg tensile lub zog yog 800MPa, uas yog hais txog 30% siab tshaj li 304 stainless hlau zoo tib yam

2. Zoo heev toughness: tom qab kev kho cua sov, elongation ≥15%, zoo heev cuam tshuam

3. Corrosion kuj: 316 stainless hlau substrate, kev ua tau zoo heev hauv ntsev tsuag ib puag ncig

4. Kev ua haujlwm raug: tag nrho xov dov txoj kev, kom ntseeg tau qhov tseeb qhov tseeb thiab nto zoo
