Laakiin sidee baad ku garan kartaa midka ku habboon mashruucaaga?

Tilmaamahan dhammaystiran, waxaan isbarbardhigeynaa4140 vs 4130 vs 4340 birta baararkacabbirrada muhiimka ah sida halabuurka kiimikada, sifooyinka farsamada, adkaanta, alxanka, daaweynta kulaylka, iyo ku habboonaanta codsiga - ka caawinta injineerada, farsameeyayaasha, iyo iibsadayaasha inay gaaraan go'aanno agab oo xog ogaal ah.

1. Hordhac ku saabsan 4140, 4130, iyo 4340 Birta Baararka ah

1.1 Waa maxay Biraha Daawaha Yar?

Biraha daawaha hooseeya waa bir kaarboon ah oo ay ku jiraan xaddi yar oo walxo isku-dhafan sida chromium (Cr), molybdenum (Mo), iyo nikkel (Ni) si loo hagaajiyo sifooyinka gaarka ah.

1.2 Dulmar Guud oo ku saabsan Fasal kasta

  • Birta 4140Bir kala duwan oo bixisa xoog iyo adkeysi aad u fiican, oo si weyn loogu isticmaalo sameynta qalabka, qaybaha baabuurta, iyo injineernimada guud.

  • Birta 4130: Waxaa loo yaqaanaa adkeysigeeda sare iyo alxanka, oo inta badan loo isticmaalo duulista hawada iyo ciyaaraha mootooyinka.

  • Birta 4340: Daawaha nickel-chromium-molybdenum oo leh xoog aad u sarreeya iyo iska caabbinta daalka, oo loogu talagalay isticmaalka hawada sare iyo kuwa culus.
