Tag nrho - xov studs(tseem hu ua tag nrho threaded rods, threaded tuav, los yog stud bolts) yog qhov tseem ceeb fasteners siv nyob rau hauv kev tsim kho, kav dej, machinery, marine, thiab industrial tej yaam num. Kev xaiv ntawm cov pa roj carbon steel, 304 stainless hlau, thiab 316 stainless hlau ncaj qha cuam tshuam rau cov kav ntev, corrosion kuj, kev pab lub neej, thiab tag nrho cov nqi. Phau ntawv qhia no piav qhia txog qhov sib txawv tseem ceeb los pab koj xaiv txoj cai.
1. Khoom siv hauv paus & Tshuaj muaj pes tsawg leeg
Cov pa roj carbon steel tag nrho - Xov Studs
Qhov feem ntau "zoo tib yam" threaded pas nrig. Ua los ntawm qis lossis nruab nrab carbon steel (xws li Q235, 1018, 4.8 / 8.8 qib). Relies on nto txheej zoo lizinc plating, kub -dip galvanizing, los yog oxide dubrau kev tiv thaiv xeb yooj yim. Tsis muaj ntuj corrosion kuj.
304 Stainless Hlau Txhuas -Tshuaj Studs
Austenitic stainless hlau (A2 qib) nrog18% chromium thiab 8% npib tsib xee. Ua tus kheej- kho cov txheej txheem oxide passive uas tiv thaiv oxidation thiab corrosion me ntsis. Dav siv rau kev siv dav dav - siv sab nraum zoov thiab tu cev.
316 Stainless Hlau Txhuas -Tshuaj Studs
Marine- qib stainless hlau (A4 qib). Raws li 304 tab sis ntxiv2% - 3% molybdenumthiab ntau dua cov ntsiab lus nickel. Muab superior tiv thaiv rau chlorides, acids, thiab seawater corrosion.
2. Qhov tseem ceeb ntawm kev ua tau zoo sib txawv
Corrosion Resistance
Cov pa roj carbon steel: pluag. Rusts sai sai hauv cov dej noo, nag, lossis ntsev ib puag ncig thaum lub txheej puas lawm.
304 stainless hlau: Zoo. Ua tau zoo nyob hauv tsev, hauv dej tshiab, khoom noj khoom haus, thiab sab nraum zoov sab nraum zoov. Tsis zoo tagnrho rau cov ntug hiav txwv dej los yog tshuaj lom neeg raug.
316 stainless hlau: Zoo heev. Tiv thaiv dej hiav txwv, tshuaj tsuag ntsev, tshuaj, thiab siab -chloride ib puag ncig. Zoo tagnrho rau marine, ntug hiav txwv dej, thiab industrial tej yaam num.
Mechanical Strength
Cov pa roj carbon steel: Siab zog (tshwj xeeb tshaj yog qib 8.8/10.9). Muaj zog nro tab sis poob kev ua haujlwm tom qab xeb.
304 stainless hlau: Lub zog nruab nrab (A2-70). Stable, ductile, tsis nkig.
316 stainless hlau: Zoo ib yam li 304 tab sis nrog zoo siab - kub stability.
Ntsev Txau Lub Neej
Carbon steel: 24-48 teev (zinc{2}}plated)
304 stainless hlau: 48-72 teev
316 stainless hlau: 100–{2}} teev
Nqi
Los ntawm qis tshaj mus rau siab tshaj:Carbon steel <304 stainless hlau <316 stainless hlau316 feem ntau raug nqi 20% -30% ntau dua 304 vim cov ntsiab lus molybdenum.

4. Cov lus nug uas nquag nug
Q: Kuv puas tuaj yeem siv 304 studs nyob ze dej hiav txwv?
A: Tsis pom zoo. Cov dej ntsev ua rau pitting corrosion sai. Siv 316 hloov.
Q: Cov ntaub ntawv twg yog qhov zoo tshaj plaws rau kev siv mus ntev - sab nraum zoov?
A: 304 rau thaj chaw hauv av; 316 rau ntug hiav txwv dej los yog tshuaj lom neeg ib puag ncig.
