904L Stainless Hlau Electropolished raj
904L Stainless Hlau Electropolished raj
904L electropolished stainless steel tubing is a high-alloy, low-carbon, austenitic stainless steel with a smooth, polished surface. Nws muaj zoo heev corrosion thiab pitting resistance nyob rau hauv cov chaw hnyav, ua rau nws xaiv qhov kev lag luam zoo tshaj plaws li tshuaj lom neeg, chaw muag tshuaj, thiab kev cia siab. Lub tshuab hluav taws xob txheej txheem txhim kho cov khoom siv tau txais cov khoom siv, tsim cov chaw passivated, huv si uas tiv thaiv oxidation ntxiv.
