Duplex Steel: Cov khoom siv muaj zog thiab corrosion kuj
Duplex Steel: Ib qho kev piav qhia
Duplex steel yog ib hom stainless hlau uas yog tus yam ntxwv ntawm nws lub zog siab thiab zoo heev corrosion kuj. Nws yog ob-theem microstructure uas muaj ob qho tib si austenitic thiab ferritic nplej. Qhov kev sib xyaw tshwj xeeb ntawm microstructures no ua rau cov khoom siv nrog cov khoom zoo dua thaum piv rau cov tsoos austenitic thiab ferritic steels.
Cov khoom muaj pes tsawg leeg ntawm duplex steel sib txawv nyob ntawm seb qib ntawm cov khoom. Feem ntau, nws muaj nyob ib ncig ntawm {{0}} feem pua chromium, 4-7 feem pua npib tsib xee, thiab 0.2-0.3 feem pua nitrogen. Lwm cov khoom xws li molybdenum, tooj liab, thiab tungsten kuj tseem tuaj yeem raug ntxiv los txhim kho cov khoom tshwj xeeb ntawm cov khoom.
Mechanical Properties ntawm Duplex Steel
Duplex steel muaj cov cuab yeej zoo heev uas ua rau nws yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv. Cov lus hauv qab no qhia txog cov khoom siv kho tshuab ntawm duplex steel:
Qib Tensile Strength (MPa) Yield Strength (MPa) Elongation (%) Hardness (HB)
2205 620-880 450 25-30 293
2507 750-1000 550 25-30 310
Raws li koj tuaj yeem pom, duplex steel muaj lub zog tensile siab thiab lub zog tawm los, uas ua rau nws tsim nyog siv rau hauv cov ntawv thov kev ntxhov siab. Nws kuj muaj qhov zoo elongation feem pua, uas txhais tau hais tias nws tuaj yeem tsim rau hauv ntau yam duab yam tsis tau tawg lossis tawg. Thaum kawg, nws qhov hardness yog piv rau lwm hom stainless hlau, ua rau nws tiv taus hnav thiab tsim kua muag.
