EN 10295:2002 gaw, European wuhpung wuhpawng (CEN) kaw nna galaw shapraw ai katsi ai hpe ninghkap lu ai n-gang n-gang ni a matu hpaji masa madang rai nga ai, dai hta madung hku nna, n-gun n-gun n-rawng ai n-gang n-gang ni a ra kadawn ai arung arai ni, tsi mawan ni, jak rung atsam ni, chyam dinglik ai ladat ni hte jai lang ai shara ni hpe madung tawn nna ka da ai. Ndai kaw gaw, madang a madung lam ni hpe lachyum shaleng ai lam rai nga ai:
1. Standard hpe jai lang ai lam a jahpan
EN 10295:2002 gaw nbung katsi ai shara hta lang ai katsi ai hpe n hkam sharang lu ai n-gang n-gang ni a matu htuk manu ai, ndai casting ni hpe bungli galaw ai shara hta wan wut ai shara, katsi ai arung arai ni, gas turbine, aero engine hte kaga hkauna ni hta lang ai, grai kaja ai nbung katsi ai oxidation hpe ninghkap lu ai atsam hte nbung katsi ai lam grai law hkra ra ai.
2. Arung arai ni ra ai
-Chemical composition: Ndai madang gaw, nbung n-gun hpe n-gun n-ja ai n-gang n-gun n-gun n-rawng ai n-gang ni a chemical n-gun hpe asan sha tsun da ai, dai hta carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) zawn re ai madung lam ni lawm ai. Ndai lam ni a daw gaw, n-gun ja ai oxidation hpe ninghkap lu ai atsam hte, n-gun dat ni a n-gun hpe hkra machyi shangun ai.
-Alloy element: chromium gaw madung alloy element rai nna, n-gang a n-gun kaba ai oxidation resistance hpe grau kaja hkra galaw na matu lang ai; silicon hte aluminum gaw auxiliary elements hku nna, oxide layer a ngang grin ai lam hpe jat ya lu ai, raitim, grai law ai gaw jak rung atsam ni hpe shayawm ya lu na re.
3. Ladat hte seng ai atsam
-N-gun ja ai n-gun: Heat hpe hkam sharang lu ai n-gang n-gun n-gun ni gaw, nbung katsi ai shara hta shanhte hpe htaw sa lu ai atsam hpe hkam la lu na matu, nbung katsi ai shara hta n-gun kaba hpe n-gun ja hkra galaw ya ra ai.
-elongation hte hkra machyi ai lam ni hpe hkra machyi shangun ai: Dai madang gaw, shanhte a plasticity hte hkra machyi ai lam hpe ninghkap lu ai atsam hpe n-gun ja ai shara ni hta hkam sharang lu na matu, galu kaba ai lam hte hkra machyi ai lam ni hpe mung tsun da ai.
4. Hpaji sawk ai ladat
-Ultrasonic sawk sagawn ai lam: Casting a n-gun n rawng ai hte nsen n kaja ai majaw, ultrasonic detection gaw kata na n kaja ai lam ni hpe mu lu na matu madung ladat rai nga ai. Casting kata na high-frequency nsen hpe madun dan ai hku nna, nbung hka htung, shrinkage hole hte sand myi zawn re ai n kaja ai lam ni hpe mu lu ai.
-Common n kaja ai lam ni hte byin pru wa ai lam ni: Ndai madang hta, n-gun n rawng ai lam ni (stoma, nhpu hka htung, hka lim ai hka htung, etc.) hte shanhte a lam ni hpe mung, quality hpe hkang lu na matu, n-gun jaw ai lam ni hpe mung tsun da ai.
5. Application field .
EN 10295:2002 hta n-gun n rawng ai n-gang n-gang ni hpe lawu na field ni hta grai lang ma ai:
-Industrial wan wut: wan wut npu, katsi ai arung arai ni, etc., nbung katsi ai hpe ninghkap lu ai atsam hte oxidation hpe ninghkap lu ai atsam ni ra ai.
-N-gun rawng ai arung arai ni: gas turbine, aero-engine, etc., nbung n-gun hte n-gun n-gun grai ja ai hpe hkam sharang ra ai.
-Kaga nbung laru kaba ai makau grup yin: wan jak, chemical jak, etc.
6. Kaga masat masa ni hte kanawn mazum ai lam
EN 10295:2002 gaw nbung katsi ai hpe ninghkap lu ai n-gang n-gang n-gang ni a ginra hta ahkyak ai madang langai rai nga ai, dai gaw kaga European madang ni (10025 10025 zawn re ai) hte rau European n-gang madang masa hpe hpaw shabawn da ai.
