ASTM-SA516Gr60Z35 ogaanshaha cilladaha saxanka birta:
1. SA516Gr60 heerka fulinta: American ASTM, ASME standards
2. SA516Gr60 waxaa iska leh weelka cadaadiska heerkulka hooseeya oo leh saxan bir kaarboon ah
3. Halabuurka kiimikada ee SA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Qalabka makaanikada ee SA516Gr60
SA516Gr60 xoogga xajinta ee 70 kun rodol/inji laba jibaaran, curiyaha ugu muhiimsan waa C Mn Si ps control ayaa go'aamisa waxqabadkiisa.Walxaha kale ee raadraaca yarAsme Standard Specification ee taarikada birta kaarboon ee weelasha cadaadiska heerkulka hooseeya.
5. Heerka gaarsiinta SA516Gr60
Saxanka birta ah ee SA516Gr60 waxaa inta badan lagu bixiyaa qaab duuban, saxanka birta sidoo kale waa la bedeli karaa ama stress-ka dhimista, ama caadiyeynta iyo amarka dhimista walaaca.
SA516Gr60 dhumucdiisuna> 40mm saxan bir ah waa in caadi.
Ilaa uu si kale u qeexo dalbadaha, dhumucda saxanka birta ≤1.5in, (40mm), marka ay jiraan shuruudo adag oo adag, waa in caadi laga dhigaa.
6. SA516Gr60 waxaa loo isticmaalaa in lagu soo saaro weelka alxanka gariiradda hal-lakabka ah, weelka alxanka gariiradda gacmo-lakab badan, weel dhaymo badan oo lakab ah iyo laba iyo saddex nooc oo kale oo weel iyo weelasha cadaadiska heerkulka hooseeya.Si ballaaran loo isticmaalo batroolka, warshadaha kiimikada, saldhigga korantada, kuleyliyaha iyo shaqooyinka kale, loo isticmaalo soo saarista reactors, kulaylka, kala-soocida, haamaha wareega, haamaha saliidda iyo gaaska, haamaha gaaska dareeraha ah, durbaanka kululeeyaha, dhululubada uumiga batroolka dareeraha ah, saldhigga tamarta tuubooyinka biyaha ee cadaadiska sare leh, Volut marawaxadaha iyo qalabka kale iyo qaybaha kale.?
7. Marka austenite si tartiib ah loo qaboojiyo (oo u dhiganta qaboojinta foornada, sida ku cad sawirka 2 V1), alaabada isbeddelku waxay ku dhow yihiin qaabdhismeedka dheellitirka, kuwaas oo ah pearlite iyo ferrite.Kordhinta heerka qaboojinta, taas oo ah, marka V3> V2> V1, qaboojinta austenite ayaa si tartiib tartiib ah u kordheysa, iyo qadarka ferrite ee degdega ah ayaa noqda mid yar oo yar, halka qadarka pearlite uu si tartiib tartiib ah u kordho, qaab-dhismeedkuna wuu fiicnaanayaa.Waqtigan xaadirka ah, qadar yar oo ferrite degdeg ah ayaa inta badan lagu qaybiyaa xadka badarka.
8. Sidaa darteed, qaabka v1 waa ferrite+pearlite;Qaab dhismeedka v2 waa ferrite + sorbite;Qaab-dhismeedka yar-yar ee v3 waa ferrite+troostite.
9. Marka heerka qaboojinta uu yahay v4, qadar yar oo ah ferrite iyo troostite (mararka qaarkood qadar yar oo bainite ah ayaa la arki karaa) ayaa soo da'aya, iyo austenite inta badan waxaa loo beddelaa martensite iyo troostite;Marka heerka qaboojinta v5 uu dhaafo heerka qaboojinta muhiimka ah, birta ayaa gebi ahaanba isu rogtay martensite.
10. Isbeddelka birta hypereutectoid waxay la mid tahay tan birta hypoeutectoid, iyada oo farqiga u dhexeeya ferrite uu soo da'ayo marka hore kan dambe iyo cementite ayaa marka hore sii da'da hore.
