Cov hlau: Cov pa roj carbon steel, tseem hu ua carbon steel, yog hais txog cov ntsiab lus carbon tsawg dua 2.11% Wc hlau carbon hlau. Ntxiv rau carbon hlau feem ntau muaj qee qhov me me ntawm carbon, manganese, sulfur, phosphorus. Cov pa roj carbon steel tau raug faib raws li kev siv cov txheej txheem carbon steel, carbon tool steel thiab txiav steel peb pawg, carbon steel hlau tau muab faib ua ob hom kev tsim kho steel thiab tshuab qauv hlau. Raws li kev ua tau zoo ntawm cov hlau tuaj yeem raug faib ua cov pa roj carbon steel zoo tib yam carbon hlau (phosphorus, sulfur siab dua), cov pa roj carbon zoo dua (phosphorus, sulfur qis dua) thiab cov hlau zoo (phosphorus, sulfur qis dua) Cov steel zoo.
Stainless hlau:Stainless hlau yog luv rau stainless acid-pov thawj hlau. Nws yog qhov muaj zog tiv thaiv kev tsis muaj zog corrosive nruab nrab xws li huab cua, chav dej, dej los yog xeb nrog stainless hlau. Tshuaj tiv thaiv nruab nrab (acid, alkali thiab ntsev tshuaj lom neeg ua haujlwm Yaig) hu ua corrosion-resistant steel qib hlau. Vim tias cov tshuaj lom neeg muaj pes tsawg leeg ntawm qhov sib txawv ntawm ob qho ntawm lawv qhov kev txhim kho corrosion ntawm qhov sib txawv stainless hlau feem ntau tiv taus qhov corrosion ntawm cov tshuaj nruab nrab, thaum cov kua qaub-resistant hlau feem ntau stainless hlau.
Nrig tooj dag:Cov tooj dag yog ib qho sib txuas ntawm tooj liab thiab zinc. Cov tooj dag ua los ntawm tooj liab thiab zinc yog hu ua tooj dag zoo tib yam. Kev siv tooj daj yog feem ntau siv hauv kev tsim cov qub, kav dej, cua txias hauv tsev thiab sab nraum lub tshuab txuas txuas rau raj thiab duab cua. Ordinary tooj dag yog tooj liab-zinc binary alloy, zinc cov ntsiab lus ntawm ntau qhov loj dua, yog li chav sov ntaub so ntswg kuj tseem sib txawv. Raws li daim duab binary xeev daim duab ntawm Cu-Zn, muaj peb hom tooj dag ntawm chav tsev kub: tooj dag muaj tsawg dua 35% ntawm zinc, lub microstructure ntawm chav tsev kub los ntawm ib-theem α cov tshuaj tiv thaiv, hu ua rass tooj dag; zinc Tus nqi tooj dag nyob hauv qhov ntau ntawm 36% txog 46%, microstructure ntawm chav tsev kub los ntawm (α + β) ob theem, uas yog hu ua (α + β) tooj dag (ob theem ua tooj dag) )% ~ 50% tooj dag, microstructure ntawm chav sov tsuas yog los ntawm β theem, hu ua as tooj dag.
Xaus:Peb cov khoom siv rau ntau lub sijhawm sib txawv. Cov neeg ua haujlwm yuav tsum siv lawv cov khoom siv raws li cov kev mob, xws li kub, siab, tshaj tawm, thiab lwm yam ntxiv tom qab ntawd txiav txim siab xaiv cov khoom tsim nyog.
