Aqoonta birta aan birta lahayn
●304 Birta Aan Lahayn
304 steel waa shay aad u isku dhafan oo caadi ahaan loo isticmaalo soo saarista qalabka iyo qaybaha u baahan sifooyin guud oo heer sare ah, oo ay ku jiraan iska caabbinta daxalka iyo qaabaynta.Si loo hubiyo iska caabbinta daxalka ee dabiiciga ah, birta aan lahayn waa in ay ka kooban tahay ugu yaraan 18% chromium iyo 8% nikkel.
Heerka
Halabuurka 304 birta ayaa door muhiim ah ka ciyaara go'aaminta caabbinta daxalka iyo qiimaha.Inkasta oo nikkel (Ni) iyo chromium (Cr) ay yihiin walxaha ugu muhiimsan, qaybo kale ayaa laga yaabaa inay ku lug yeeshaan.Heerarka badeecada ayaa qeexaya shuruudaha gaarka ah ee birta 304.Waxaa guud ahaan laga fahmay warshadaha in haddii maadada Ni ay ka badato 8% iyo ka kooban Cr uu dhaafo 18%, waxaa loo kala saari karaa 304 bir ah.Taasi waa sababta inta badan loogu yeero 18/8 birta aan lahayn.Waa in la ogaadaa in ay jiraan xeerar cad oo ku jira heerarka wax soo saarka ee ku habboon ee 304 birta, xeerarkani waxay ku kala duwanaan karaan qaabka iyo qaabka birta aan fiicnayn.
