ASTM A299 GR.A Mn-Si Alloy Pressure weelka saxan bir ah

Birta kaarboon ee leh saxan Manganese-Silicon SA299 Fasalka A,SA299 Fasalka B ee hoos yimaada birta heerka ASME SA 299/SA 299M A 299 /A 299M. Sida daawaynta kulaylka, saxan bir A299 Fasalka A iyo A299 Fasalka B siman iyo in ka yar 50 milimitir waxaa sida caadiga ah giringiriyey in xaaladda sida giringiriyey, cadaadiska weelka birta saxan.
Marka loo eego heerka ASTM A299/A299M, saxan bir ah A299 Fasalka A iyo A299 Fasalka B waa in lagu doortaa xaaladaha farsamo ee soo socda: S1.Vacuum treatment, S2. Falanqaynta alaabta. S3. Daawaynta kulaylka alxanka ka dambeeya ee la mid yahay ee tigidhada tijaabada farsamada, S4. Tijaabada xiisadda dheeraadka ah, S5. Imtixaanka saamaynta Charpy V-notch, S6. Tijaabada miisaanka hoos u dhaca, S7. Tijaabada xiisadda heerkulka sare.

ASTM A299 Fasalka saxan bir kuleyliyaha ah, ASME SA299 Fasalka Weel cadaadis bir ah ayaa lagu qeexay birta kaarboonka iyo Manganese-Silicon. Sida saxan khafiif ah SA299 Fasalka A kaas oo laga soo saaray gariiradda birta SA299 Fasalka A oo lagu diyaariyey iyada oo aan la daaweyn kulayl ama kaliya walaaca yareynaya, shuruudaha dheeraadka ah, oo ay ku jiraan shuruudaha tijaabada dheeraadka ah iyo warbixinta natiijooyinka baaritaan dheeraad ah ayaa lagu dabaqi doonaa A20 / Heerka birta A20M.

Shuruudaha Farsamada & Adeegyada Dheeraadka ah:

• Tijaabada xiisadda sare
• Tijaabada saamaynta heerkulka hoose
• Caadiyan taarikada qaro weyn ee ka badan 40mm
• Daawaynta kulaylka kadib alxanka la mid ah (PWHT)
• Waxaa lagu soo saaray shahaadada tijaabada Milli Orginal Mill ee hoos timaada EN 10204 FORMAT 3. 1/3. 2
• Rasaasta qarxinta iyo rinjiyeynta, Goynta iyo alxanka sida waafaqsan shuruudaha isticmaalaha
