** 1. Yog 1018 siab carbon hlau? **
Tsis yog, 1018 steel yog tsis muaj pa roj carbon hlau. Nws tau cais raws li cov pa roj carbon tsawg (lossis me me) hlau. Nws muaj cov ntsiab lus carbon ntawm kwv yees li 0.18%, uas muab nws zoo devility thiab weldability tab sis qis zog piv rau cov roj carbon ntau dua.
** 2. Yog 4140 siab carbon hlau? **
Tsis yog, 4140 hlau tsis raug cais raws li cov roj carbon ntau. Nws yog ib qho nruab nrab cov hlau steel, tshwj xeeb ib chomium - molybdenum alloy hlau. Nws cov ntsiab lus carbon nyob ib puag ncig 0.40%, uas muab tso rau hauv nruab nrab cov pa roj carbon ntau. Nws lub zog siab yog los ntawm cov ntsiab lus carbon cov ntsiab lus ua ke nrog nws cov ntsiab lus xws li chromium thiab molybdenum.
** 3. Yog 4340 muaj zog tshaj 4140? **
Yog, 4340 feem ntau muaj zog thiab nruj tshaj 4140. Lub ntsiab lus tseem ceeb yog 4340 muaj ob lub caij nyoog ntxiv. Nickel significantly enhances the toughness and strength of the steel, especially in larger cross-sections. Qhov no ua rau 4340 zoo dua rau high- lub zog kev thov yuav tsum muaj kev cuam tshuam zoo.
** 4. Uas yog qhov nyuaj, 1018 lossis 4140 hlau? **
4140 steel hlau yog qhov nyuaj dua 1018 hlau. In their most common conditions (hot-rolled or cold-finished), 4140 has a much higher hardness. Tseem ceeb tshaj, 4140 tuaj yeem yog kho cua sov (quenched thiab lub zog
** 5. Yog 440 steel siab - carbon? **
Yog, 440 steel yog suav hais tias yog qhov siab-} cov hlau. Nws yog tsev neeg ntawm Martensitic Stainless hlau. Feem ntau cov qhab nia, 440C, muaj cov ntsiab lus carbon txog 0.95 {{}} 1.20%, uas yog heev. Cov ntsiab lus carbon ntau tso cai tso cai rau nws kom ua kom muaj kev phom sij, ua rau nws nyiam riam, bearings, thiab lwm yam kev siv ua kom tau cov khoom siv nyuaj.
