ASTM A36 kaarboon birta birta ah

ASTM A36u hoggaansama heerarka Bulshada Maraykanka ee Tijaabinta iyo Qalabka, iyo tuubooyinka birta kaarboon ee caadiga ah ee la soo saaro si waafaqsan jaangooyooyinka ASME waxay la mid yihiin walxaha Q235 ee Shiinaha, kaas oo iska leh heerka American Standard iyo saxanka birta ee caadiga ah.

ASTM A36 waxay ku habboon tahay jeexjeexa, dhejinta iyo qaababka alxanka ee loo isticmaalo buundooyinka iyo dhismayaasha, waxaana badanaa loo isticmaalaa soo saarista mishiinada. ASTM A36 waxay leedahay goyn wanaagsan iyo waxqabadka alxanka. Marka la eego farsamaynta goynta, waxay leedahay waxqabad xasiloon, goyn yar oo qallafsan oo si fudud loo alxan karo. Waxaa si weyn loogu isticmaalaa warshadaha wax soo saarka sida wax soo saarka qalabka dheeriga ah, biraha iyo warshadaha kiimikada, iyo flanges.

Heerka fulinta ee ASTM A36: ASTM A36/A36M-03a.
Walxaha kiimikada iyo ka kooban ASTM A36:

1. Qaybaha: C (carbon), Si (silikon), Mn (manganese), P (phosphorus), S ( baaruud), Cu (naxaas)
2. Halabuurka: C: ≤0.25, Si≤0.40, Mn: ≤0.80-1.20, P≤0.04, S: ≤0.05, Cu≥0.20. (haddii ay noqoto birta naxaasta ku jirta)

Shuruudaha farsamada ASTM A36: ogaanshaha cillad, Z15Z35 dhumucdiisuna waxay tahay jihada shuruudaha waxqabadka, xoogga sare, adagaanta sare iyo shuruudaha kale.

 

Qalabka makaanikada ee ASTM A36:
Awood wax-soo-saar ——≥250MPa
Xoog xajin - 400MPa-550MPa
Kordhinta nasashada ka dib——≥20% (aan saamayn lahayn)

Heerka keenista ASTM A36:
Ma jiraan cillado sida dildilaacyo, goobooyin, iyo nabarro dusha sare ah. Heerka gaarsiinta ee saxanka birta ah waa mid kulul, waxaana lagu bixin karaa iyadoo loo eegayo shuruudaha farsamada sida caadiga ah, xajinta, iyo duubista xakamaynta; ogaanshaha cilladda waxaa loo samayn karaa sida 1 baaritaan, 2 baaro, iyo 3 baaro; Kordhinta dhumucda waxay sameyn kartaa z15, z25, z35.
