Qhov sib txawv ntawm cov khoom pwm 2738,718,4Cr13

2738, 718, thiab 4Cr13 yog cov khoom siv dav siv hauv kev tsim cov pwm. Cov ntaub ntawv no muaj cov khoom sib txawv thiab cov khoom sib txawv uas ua rau lawv haum rau cov ntawv thov tshwj xeeb.

2738: Cov khoom siv no yog cov cuab yeej ua ntej-hardened hlau uas muaj nickel, chromium, thiab molybdenum. Nws muaj zoo hardness, toughness, thiab tsis kam mus corrosion thiab hnav. Nws yog feem ntau siv rau cov pwm loj thiab nyuaj hauv kev lag luam tsheb thiab hluav taws xob. Nws hardness ranges ntawm 280 mus rau 325 HB.

718: Cov khoom no yog nickel-based superalloy uas muaj chromium, cobalt, thiab molybdenum. Nws muaj kev tiv thaiv corrosion zoo heev thiab lub zog kub kub, ua rau nws tsim nyog siv rau hauv cov neeg ua haujlwm kub thiab lwm yam kev siv kub. Nws muaj qhov hardness ntau ntawm 360 txog 400 HB.

4Cr13: Cov khoom no yog martensitic stainless hlau uas muaj chromium thiab carbon. Nws muaj kev tiv thaiv zoo corrosion, kub tsis kam, thiab hardness, ua rau nws haum rau siv nyob rau hauv pwm nrog qis dua qhov yuav tsum tau rau precision thiab nto tiav. Nws hardness ranges ntawm 195 mus rau 225 HB.

Nyob rau hauv cov ntsiab lus, 2738 yog haum rau loj thiab complex pwm uas yuav tsum tau zoo hardness thiab toughness, 718 yog haum rau high-temperature daim ntaub ntawv uas yuav tsum tau zoo heev corrosion kuj thiab lub zog, thaum 4Cr13 yog haum rau pwm nrog qis dua qhov yuav tsum tau rau precision thiab nto tiav uas yuav tsum tau. zoo corrosion thiab kub tsis kam.
