Lub npib tsib xee-chrome cov xov hlau tau siv dav ua cov hluav taws xob cua sov thiab cov hluav taws xob hluav taws xob hauv kev lag luam me metallurgical, kev lag luam tshuaj thiab kev lag luam hluav taws xob, thiab lwm yam.
Cov xaim hluav taws xob ib colo muaj cov hluav taws xob ntau dua, kev tiv thaiv zoo, thiab nws kuj muaj lub zog zoo ntawm qhov kub siab.
Cov yam ntxwv tseem ceeb ntawm Ni-CR thiab Ni-Cr-Fe Hluav Taws Xob Cua Sov Alloys
