Nyob rau hauv siab - ib puag ncig kev ntxhov siab xws li aerospace turbine shafts, nuclear reactors, thiab oilfield downhole cov cuab yeej, cov qauv kev ncaj ncees ntawm cov ntaub ntawv tseem ceeb heev. Rau kev yuav cov thawj coj thiab engineers, cov ntsiab lus mob tseem ceeb thaum muab khoomGH4169 kub-forged round barssuav nrog:
Internal segregation ("freckles"):Loj - cov kab kab uas hla feem ntau raug kev txom nyem los ntawm cov tshuaj lom neeg tsis sib xws, uas tuaj yeem ua rau muaj kev puas tsuaj loj heev.
Inconsistent grain loj:Kev tswj tsis zoo forging tuaj yeem ua rau cov nplej ntxhib, txo qis siab - lub neej qaug zog.
Centerline porosity:Tsis txaus forging ratios tuaj yeem tawm hauv cov voids hauv cov tub ntxhais bar.
NtawmGnee Steel, peb tshem tawm cov kev pheej hmoo no. Raws li ib tugTier 1 manufacturers, peb ua haujlwmVIM+VAR processesthiab siab -txo qis forging thev naus laus zis kom ntseeg tau tias xoom- tsis zoo.

A: Yog lawm.GH4169 yog Suav lub npe uas qhia ncaj qha rau lub ntiaj tebUNS N07718specification. Peb cov khoom siv sib hloov tau thoob ntiaj teb thiab yog siv los ntawm Tier-1 aerospace thiab lub tuam txhab hluav taws xob thoob ntiaj teb.
Q2: Vim li cas kuv thiaj yuav tsum xaiv forged tuav hla dov tuav rau cov kab loj?
A: Forged bars (tshwj xeeb tshaj yog saum 100mm) muab cov qauv denser ntau thiab cov nplej zoo dua li dov, uas yog qhov tseem ceeb rau covKev ntseeg ruaj khovntawm rotating engine shafts thiab turbine discs.
Q3: Koj puas tuaj yeem muab GH4169 rods rau NACE MR0175 qaub roj ib puag ncig?
A: Yog lawm. Thaum tshav kub kub-kho rau qhov siab tshaj plaws ntawm 40 HRC, peb GH4169 tau ua raws li tag nrhoNWS MR0175, ua rau nws zoo tagnrho rau siab -cov roj thiab roj cov cuab yeej downhole.
