D2 Tuag Steel Phaj

1.2379 yog cov cuab yeej hlau nrog cov ntsiab lus carbon ntawm 1.5 feem pua, cov ntsiab lus chromium ntawm 11.5 feem pua, thiab hardness txog li 60HRC tom qab kev kho cua sov. Nws yog ib hom semi-stainless hlau. D2 steel muaj kev hnav zoo thiab muaj zog toughness. Qhov tsis zoo yog tias qhov corrosion kuj yog me ntsis tsis txaus. Nws yog ib hom hlau uas tsim nyog rau kev siv tswv yim. Bob Dozier nyiam siv D-2. D2 steel yog hnav-resistant, me ntsis deformed txias ua hauj lwm tuag steel, cua-hardened cuab yeej hlau. D2 steel tuaj yeem siv los tsim cov hlau ua haujlwm txias nrog cov ntu loj, cov duab nyuaj, muaj kev cuam tshuam siab, thiab hnav tsis kam, xws li silicon steel ntawv tuag, txias txiav txiab, trimming tuag, thiab lwm yam.

Cov ntaub ntawv yooj yim
1.2379 Cov pa roj carbon siab thiab siab chromium txias ua haujlwm tuag hlau dav siv nyob hauv lub ntiaj teb yog cov hlau ledeburite nrog siab.
hardenability, hardenability thiab siab hnav tsis kam; zoo kub oxidation kuj, xeb kuj tom qab quenching
thiab polishing Muaj peev xwm zoo, kev kho cua sov me me deformation.
