Dab tsi yog cov yam ntxwv zoo ntawm 09CuPCrNi-A weathering steel?

09CuPCrNi-A yog qib steel nrog cov huab cua tsis zoo, uas yog siv dav hauv cov choj, vaj tsev, mines thiab lwm qhov chaw.Hauv qab no kuv yuav qhia cov yam ntxwv zoo heev ntawm cov huab cua no steel.
(Kom kawm paub ntxiv txog qhov cuam tshuam ntawm cov khoom steel tshwj xeeb, xws liHuab cua Resistant Steel Phaj, koj tuaj yeem tiv tauj peb)
1. Cov huab cua tsis zoo
Nyob rau hauv 09CuPCrNi-A steel, tooj liab, chromium, npib tsib xee thiab lwm yam khoom raug ntxiv, thiab tib lub sijhawm, cov ntsiab lus ntawm Si thiab P hauv cov hlau yog tswj, uas ua rau cov hlau muaj huab cua tsis zoo.Hauv qhov hnyav sab nraud, nws tuaj yeem tiv taus oxidation thiab corrosion zoo, yog li nws tuaj yeem siv tau ntev.
2. Cov khoom siv kho tshuab zoo heev
09CuPCrNi-A steel kuj muaj kev ua tau zoo ntawm cov khoom siv kho tshuab.Nws lub zog tensile yog 435-490MPa, yield zog mus txog 290-345MPa, thiab elongation ntawm tawg tuaj yeem ncav cuag 22%.Cov no yog cov ntaub ntawv zoo heev.

3. Yooj yim rau txheej txheem thiab vuam
09CuPCrNi-A steel ua tau zoo heev hauv machining thiab vuam.Nws muaj qhov zoo tshaj plaws weldability thiab kub tsis kam, thiab yooj yim rau tshuab vim nws cov yas siab thiab toughness.
4. Tsawg tus nqi tu
Thaum siv 09CuPCrNi-A cov khoom siv, nws cov nqi kho mob tsawg heev.Vim nws cov huab cua tsis zoo, nws tsis xav tau kev saib xyuas ntau thiab kev saib xyuas thaum siv.Qee lub sij hawm qhov chaw ib puag ncig hnyav heev, kev siv cov khoom siv no tuaj yeem txo cov haujlwm ua haujlwm thiab txuag sijhawm thiab nqi ntau.
