Cov xim hlau ntawm cov neeg ua ntej ntawm cov hlau ntshiab rau kev thim rov qab

1. Txhais cov hlau ntshiab hauv cov khoom siv hluav taws xob niaj hnub

Cov hlau ntshiab, feem ntau hu ua electrolytic hlau lossis ingot hlau, txhais tau los ntawm nws cov ntsiab lus roj carbon-tsawg (<0.025 wt%) and total impurity levels below 0.15 wt%. This section explores the metallurgical basis of purity standards, comparing ASTM AISI 1006 (99.85% Fe) with premium grades (99.99%+ Fe) used in advanced applications.
