Hauv qab no yog cov ncauj lus kom ntxaws txog cov tshuaj muaj pes tsawg leeg ntawm x52 steel.
1. Cov ntsiab lus carbon: x52 steel muaj cov ntsiab lus siab carbon, feem ntau ntawm 0.20% thiab 0.25%. Carbon yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm cov hlau, uas tuaj yeem ua rau cov tawv tawv thiab lub zog ntawm cov hlau. Nyob rau tib lub sijhawm, carbon tuaj yeem txhim kho cov cua sov thiab hnav tsis kam ntawm cov hlau.
2. Silicon cov ntsiab lus: Cov ntsiab lus silicon hauv x52 steel yog tsawg, feem ntau yog nyob nruab nrab ntawm 0.15% thiab 0.35%. Silicon tuaj yeem ua kom lub zog thiab hardness ntawm cov hlau thiab pab txo cov brittleness ntawm cov hlau. Tsis tas li ntawd, silicon tuaj yeem txhim kho corrosion kuj ntawm hlau.
3. Manganese cov ntsiab lus: Cov ntsiab lus manganese hauv x52 steel yog siab, feem ntau ntawm 1.40% thiab 1.70%. Manganese yog ib qho tseem ceeb ntawm cov hlau alloying, uas tuaj yeem ua rau lub zog thiab tawv tawv ntawm cov hlau thiab txhim kho cov weldability ntawm cov hlau. Nyob rau tib lub sijhawm, manganese tuaj yeem txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm hlau.
4. Phosphorus cov ntsiab lus: Cov ntsiab lus phosphorus hauv x52 steel yog tsawg, feem ntau yog qis dua 0.020%. Phosphorus yog ib qho impurity uas txo cov toughness thiab plasticity ntawm hlau, yog li cov ntsiab lus phosphorus yuav tsum tau tswj thaum tsim x52 steel.
5. Cov ntsiab lus sulfur: Cov ntsiab lus ntawm cov sulfur hauv x52 steel yog qis, feem ntau yog qis dua 0.010%. Sulfur yog ib qho teeb meem uas txo cov toughness thiab plasticity ntawm steel thiab ua rau kom cov brittleness ntawm hlau. Yog li ntawd, cov ntsiab lus sulfur yuav tsum tau tswj thaum tsim x52 steel.
6. Chromium cov ntsiab lus: Cov ntsiab lus chromium hauv x52 steel yog tsawg, feem ntau yog nruab nrab ntawm 0.30% thiab 1.00%. Chromium yog ib qho tseem ceeb ntawm cov hlau alloying uas tuaj yeem txhim kho corrosion kuj ntawm cov hlau thiab ua rau cov tawv tawv thiab hnav tsis kam ntawm cov hlau.
7. Cov ntsiab lus nickel: Cov ntsiab lus nickel hauv x52 steel qis, feem ntau yog qis dua 0.25%. Nickel yog cov khoom siv feem ntau siv los ua kom muaj zog thiab tawv tawv ntawm cov hlau thiab txhim kho cov weldability ntawm cov hlau. Tsis tas li ntawd, npib tsib xee kuj tuaj yeem txhim kho corrosion kuj ntawm hlau.
