AISI 4145H Tube Bir ah oo aan kala go 'lahayn
Sharaxaad Gaaban:
Waxaan bixinaa tuubooyin bir ah oo aan lahayn bir aan lahayn 4145H oo leh xoog sare, adkeysi aad u fiican, iyo iska caabin daal oo heer sare ah. Ku habboon qodista saliidda iyo gaaska, mashiinnada culus, iyo warshadaha baabuurta.
Tuubo bir ah oo aan kala go 'lahayn oo 4145H ah:
Tuubada birta ah ee aan kala go 'lahayn ee 4145H waa tuubo bir ah oo bir ah oo chromium-molybdenum ah oo xoog badan, oo loo yaqaan adkeysigeeda aadka u wanaagsan, iska caabbinta xirashada, iyo xoogga daalka. Caadiyan waxaa lagu bixiyaa xaalad damin ah oo la qaboojiyey si kor loogu qaado sifooyinkeeda farsamada, oo ay ku jiraan tamar sare iyo xoog wax soo saar. Tuubadan aan kala go'lahayn waxaa si weyn loogu isticmaalaa qodista saliidda iyo gaaska, mashiinnada culus, iyo codsiyada baabuurta, halkaas oo loo baahan yahay adkeysi sare iyo iska caabbinta saameynta. Iyada oo loo soo saaray heerarka ASTM A519, tuubooyinka aan kala go'lahayn ee 4145H waxay maraan sawir qabow oo sax ah iyo tijaabin aan burburin si loo hubiyo saxnaanta cabbirka sare iyo isku halaynta jawiyada adag.
