420F Stainless hlau yeeb nkab Mechanical Properties

420F stainless hlau yeeb nkab mechanical zog

420F stainless hlau yog martensitic stainless hlau alloy uas feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau muaj zog txhua yam thiab corrosion kuj. Lub "420" hauv nws lub npe qhia tias nws muaj kwv yees li 12-14 feem pua ​​chromium, uas muab kev tiv thaiv corrosion zoo, thiab "F" sawv cev rau "dawb machining."

Ntawm no yog cov yam ntxwv ntawm 420F stainless hlau:

1, Tensile Strength: Lub zog tensile ntawm 420F stainless hlau yog feem ntau nyob rau hauv thaj tsam ntawm 530-750 MPa (77, 000-109, 000 psi). Lub zog tensile ntsuas qhov siab tshaj plaws ntawm tensile kev nyuaj siab uas cov khoom tuaj yeem tiv taus ua ntej nws tawg.

2, Yield Strength: Lub zog tawm los ntawm 420F stainless hlau nyob ib ncig ntawm 275-460 MPa (40, 000-67, 000 psi). Yield zog yog qhov kev nyuaj siab uas cov khoom pib deform mus tas li.

3, Elongation: Lub elongation ntawm 420F stainless hlau feem ntau nyob ib ncig ntawm 15-25 feem pua. Elongation sawv cev rau qhov feem pua ​​​​nce hauv qhov ntev ntawm cov khoom siv tau ua ntej nws tawg, qhia txog nws qhov ductility.

4, Hardness: 420F stainless hlau feem ntau muaj qhov nyuaj ntawm 210-290 Brinell (HB) lossis Rockwell hardness ntawm 95-30 HRC. Hardness ntsuas cov khoom tiv thaiv rau indentation lossis khawb.

5, Impact Resistance: 420F stainless hlau nthuav tawm cov kev cuam tshuam zoo, ua kom nws nqus tau lub zog thaum lub sijhawm thauj khoom tam sim ntawd.

6, Modulus ntawm Elasticity: Modulus ntawm elasticity, tseem hu ua Young's modulus, rau 420F stainless hlau yog kwv yees li 200 GPa (29,000 ksi). Cov cuab yeej no sawv cev rau cov khoom siv lub peev xwm los deform elastically nyob rau hauv kev ntxhov siab thiab rov qab mus rau nws cov qauv qub thaum tso tawm.
