Tso lus
ASTM A 582 303 stainless hlau round bar yog dab tsi?
303 stainless hlau 18Cr-8Ni yog austenitic stainless hlau nrog ntxiv sulfur thiab/los yog selenium los txhim kho machinability. Nws yog feem ntau tsis-magnetic; nws yuav ua tau me ntsis sib nqus tom qab ua haujlwm txias. Nws ua tau zoo nyob rau hauv ib puag ncig me me corrosive; nws tsis pom zoo rau marine / ntsev tsuag ib puag ncig. Vim muaj kev pheej hmoo ntawm pitting corrosion los ntawm sulfide inclusions, qhov kub tsis sib xws ntawm qhov kub thiab txias yog txog li ntawm 760 degree, thiab qhov kub kub tsis tu ncua yog txog li 870 degree; vim carbide nag lossis daus, kev siv txuas ntxiv hauv 425-860℃ntau yam tsis pom zoo.
GNEE muab 303 stainless hlau puag ncig bar rau siab -machining ceev. Peb cov khoom tuav nyob rau hauv ntau txoj kab uas hla thiab muab kev cai ntev, tsis muaj kev sib tsoo, thiab polishing tiav . 303 stainless hlau muaj qhov zoo tshaj plaws machinability nyob rau hauv austenitic stainless hlau tsev neeg thiab yog zoo tagnrho rau CNC tshuab cuab yeej thiab tsis siv neeg threading tshuab.
