ASTM A319 gaw n-gun kaba ai shara ni hta n-gun n-gun n-gun n-gun n-gun n-gun ni hta lang ai grey cast iron arai langai mi re. Ndai madang hpe American Hpung kaw nna 1971 ning hta shawng nnan shapraw ai, 2001 ning hta bai madi shadaw ai lam ni hpe galaw ai.
Scope of application hte arawn alai
ASTM A319 masat masa gaw, n-gun kaba ai makau grup yin ni hta bungli galaw ai n-gun n-gun n-gun n-gun n-gun n-gun n-gun ni a matu htuk manu ai, grate bar, grate matut mahkai lam, grate daw ni, wan sau hta lawm ai arung arai ni, wan wut ai arung arai ni, ingot molds, glass molds, caustic hka htung ni, magri hka htung ni zawn re ai ni a matu htuk manu ai. Ndai cast iron ni gaw 1400℃F (760 degree) du hkra nbung katsi ai shara ni hta kaja ai hku galaw lu ai, raitim ndai gaw grey cay iron grade masum yawng gaw nbung katsi ai shara ting a matu htuk manu ai ngu ai lachyum n re. Nkau grade ni gaw, n-gun n law ai rai yang, n-gun n law ai sha, n-gun n law ai shara hta aten galu magam bungli galaw na matu sha htuk manu ai.
sharin hkam la ai lam
Gray cast iron hpe grade masum hku garan nna galaw ai:
Grade I: thermal shock hpe grai kaja ai hku ninghkap lu ai.
Grade II: Hka lum ai hpe hkam sharang lu ai atsam hte n-gun kaja ai n-gun (tensile n-gun gaw 30,000 psi (sh) 207 MPa hta grau kaba ai).
Grade III: Grade I hte II hta grau tsaw ai n-gun (tensile n-gun gaw 40,000 psi (sh) 276 MPa daram rai na re).
Hpaga lam galaw ai lam hte hkum hkrang ra kadawn ai lam ni
ASTM A319 madang hta, foundry a myit ra ai hku tawn da ai, n-gun n rawng ai lam hpe n tsun da ai. Ndai madang gaw kaga madang ni hpe mung tsun da ai, ASTM A48 zawn re ai, dai hta grey cast iron a matu masat da ai lam ni hpe hkrak tup tsun dan ai, dai hta n-gun ja ai, tensile n-gun, n-gun atsam, hkra machyi ai lam hpe hkra machyi shangun ai, kaga jak rung atsam ni hpe chyam dinglik ai madang ni lawm ai.
