KMTBCr28 Ob-hlau hnav-resistant luj tshib
Tsis tshua muaj lub ntiaj teb hnav-tiv taus hlau, siab chromium thiab lwm yam hlau hnav-tiv taus cam khwb cia hlau, lub hardness ntawm steel ncaj qha cuam tshuam rau vuam kev ua tau zoo, thiaj li yuav siv tau thiab installation tsuas yog txo cov hardness, yog li nws hardness tsuas yog hauv qab HRC. 40, txawm li cas los xij, nws txoj kev weldability tseem tsis zoo, yooj yim rau tawg hauv cov txheej txheem vuam. Yuav kom nrhiav tau qhov sib npaug ntawm qhov hnyav hnyav, weldability thiab cuam tshuam tsis kam, KMTBCr28 bimetal composite hnav-resistant luj tshib tau los ua thiab tau siv dav txij li xyoo 1990s. KMTBCr28 bimetallic composite luj tshib tuaj yeem tsis tsuas yog ua kom cov yeeb nkab toughness, weldability thiab lub zog (compression resistance) yuav tsum tau, tab sis kuj ua kom txaus hnav tsis kam, yog ib qho zoo tagnrho hnav-resistant yeeb nkab tov rau cov khoom thauj.
