DP dual-phase

Kev tsim tawm:

Lub thiaj li hu ua duplex stainless hlau nyob rau hauv nws cov khoom tov ntawm ferrite theem thiab austenite ntsib txhua ib nrab, feem ntau tsawg cov ntsiab lus ntawm cov ntsiab lus kuj yuav tsum tau mus txog 30%. Nyob rau hauv cov ntaub ntawv ntawm tsawg C, Cr ntsiab lus ntawm 18% mus rau 28%, Ni cov ntsiab lus ntawm 3% mus rau 10%. Qee cov hlau kuj muaj Mo, Cu, Nb, Ti, N thiab lwm yam alloying ntsiab.

 

Qhov zoo.

Cov hlau muaj cov yam ntxwv ntawm austenitic thiab ferritic stainless hlau,

1. Muab piv nrog cov ferrite, plasticity, siab dua toughness, tsis muaj chav kub brittleness, tsis kam mus rau intergranular corrosion thiab vuam kev ua tau zoo heev, thaum tseem mainta ining hlau Tsim nyog stainless hlau 475 ℃ brittleness thiab siab thermal conductivity, nrog superplasticity thiab hais txog.

2. Muab piv nrog cov austenitic stainless hlau, siab zog thiab tsis kam mus rau intergranular corrosion thiab tsis kam mus rau chloride kev nyuaj siab corrosion tau zoo tuaj.

3. Duplex stainless hlau muaj kev tiv thaiv zoo heev rau pitting corrosion kuj, tab sis kuj yog ib feem ntawm nickel stainless hlau.
