Lub luag hauj lwm ntawm ntau yam hlau ntsiab nyob rau hauv Alloy Steel Sib Tsoo Pob rau Mining

Lub luag haujlwm ntawm carbon hauv stainless hlau pob:

Cov pa roj carbon yuav tsum muaj nyob rau hauv kev tsim cov pob steel. Qhov no tshwj xeeb tshaj yog pab tsim cov cementite thiab perlite. Qhov ntau carbon nyob rau hauv stainless hlau pob, lawv yuav nyuaj dua. Tsis tas li ntawd, qhov no tseem cuam tshuam rau kev hnav tsis kam ntawm lub pob.

Lub luag haujlwm ntawm niobium hauv stainless hlau pob:

Hauv dub stainless hlau, ntxiv niobium yog ib txoj hauv kev zoo tshaj plaws los txhim kho cov cua sov ntawm cov hlau. Qhov sib ntxiv ntawm niobium pab txo cov corrosion ntawm stainless hlau pob, tshwj xeeb tshaj yog nyob rau hauv high-kub siv. Yog li ntawd, nws ua raws li stabilizer.

Lub luag haujlwm ntawm titanium: titanium

Qhov sib ntxiv ntawm txhawm rau txhim kho kev tiv thaiv pitting corrosion. Titanium yog suav tias yog ib qho stabilizer hauv stainless hlau pob alloys.

Lub luag haujlwm ntawm manganese hauv stainless hlau pob:

Manganese feem ntau siv los hloov nickel. Manganese reacts nrog oxygen thiab yog li ua raws li antioxidant. Nws yuav cuam tshuam cov khoom ntawm cov hlau, tshwj xeeb tshaj yog nws lub peev xwm hardening.

Lub luag haujlwm ntawm chromium hauv stainless hlau pob:

Chromium tshwj xeeb yog siv los ua kom cov tawv tawv thiab hnav tsis kam ntawm cov pob hlau stainless. Chromium kuj tseem paub txog nws txoj kev tiv thaiv corrosion. Hlau nrog cov ntsiab lus chromium ntau dua 12% yog suav tias yog stainless hlau.

Lub luag haujlwm ntawm silicon hauv stainless hlau pob:

Silicon plays ib qho kev tiv thaiv oxidation hauv cov hlau. Ntxiv mus, nws ua ke nrog lwm yam alloys ua rau steel ntau hnav-resistant. Ib qho me me ntawm silicon ntxiv rau cov hlau los txhim kho corrosion kuj. Silicon feem ntau yog ntxiv rau stainless hlau los txhim kho nws cov oxidation tsis kam.

Lub luag haujlwm ntawm nickel hauv stainless hlau pob:

Nickel muaj ductility zoo heev thiab tensile zog. Cov khoom no yog khaws cia ntawm qhov kub thiab txias heev. Nickel yog qhov tsim nyog rau kev tsim cov qauv austenite ntawm stainless hlau pob.

Lub luag haujlwm ntawm molybdenum hauv stainless hlau pob:

Molybdenum yog siv nyob rau hauv stainless hlau rau densities txog li 8%, tab sis feem ntau yog 2 mus rau 4%. Txawm tias nyob rau ntawm qhov sib piv qis, molybdenum tuaj yeem ua kom ntseeg tau tias nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog ntawm cov hlau.
