Heat hpe ninghkap lu ai Steel hpe lata ai.

Arung arai lata ai lam gaw madung lam ni hpe myit maju jung ra ai
Hka lum ai hpe ninghkap lu ai steel grade law law hta, cement hpun ni a bungli masa ni hpe hkan sa ai katsi ai hpe ninghkap lu ai n-gang hpe lata ai lam gaw lawu na lam ni hpe myit yu ra ai:
(1) Hka lum ai hpe ninghkap lu ai n-gang n-gang ni a bungli galaw ai nbung laru. Operating temperature ngu ai gaw, nbung katsi dik ai, nbung katsi ai hte n-gun n law dik htum hte nbung katsi ai lam hpe tsun mayu ai.
(2) Hka lum ai hpe ninghkap lu ai n-gang n-gang ni a jak lit.
(3) Nbung n-gun hpe n-gun n-ja ai n-gang n-gang hte shi a masa (nbung a n-gun n-gun, tsi mawan n-gun, etc. ni lawm ai) hte matut mahkai ai gas.
(4) Manu n law ai, dai kaw chromium n law ai hte nickel n law ai cast heat hpe n hkam jan lu ai n-gang hpe n lang ai, chromium hte nickel n-gun grai law ai.
Cement hpun ni gaw, katsi ai hpe ninghkap lu ai n-gang n-gang ni hpe jai lang ai hta, mahkrum madup ni hpe ayan shingdaw nna mahkawng da ra ai. Hpa majaw nga yang, n tara ai hku n-gun n rawng ai n-gang n-gang ni hpe n tara ai hku n-gun jaw ai lam gaw, n tara ai arung arai ni hpe lata ai lam a majaw teng sha byin pru wa ai hpe sawk sagawn ai hku nna sakse madun dan ai rai yang, nang gaw n-gun n rawng ai arung arai ni hpe bai lata ai lam hpe hkaja ai hku nna hkrat sum ai lam hpe pat shingdang na matu, galaw shapraw ai wa hpe matut mahkai mai ai, dai hpe galaw ai wa gaw, bai lata ai lam hpe bai lata la ai lam hpe jaw ya nna, jak rung de sa wa ai lam hpe madun dan ra ai.
