Ko ngā paipa rino koranu te nuinga o te wā e whakamahia ana i roto i ngā tipu hiko, ngā tipu hiko karihi, ngā kohua pēhanga teitei, ngā whakamahana pāmahana teitei, ngā whakamahana anō me ētahi atu paipa me ngā taputapu pēhanga teitei me te pāmahana teitei. He mea hanga ki te maitai waro kounga teitei, te maitai hanganga koranu me te maitai kore waikura ātete wera mā te huri wera (whakaputa, whakawhānui) te huri matao rānei (tuhi).
He hononga, he rerekētanga hoki te paipa whakarewa me te paipa tuimotu, kāore e taea te whakapoauau. Ko te paipa koura he paipa rino e ai ki te rauemi hanga (arā, te rauemi). E ai ki te ingoa, he paipa i hangaia ki te koranu. Ko te paipa tuimotu he paipa rino (tuitui me te tuimotu) e ai ki te tukanga hanga.
He momo paipa rino kore hononga te paipa koranu, e wehea ana ki te paipa koranu kore hononga hanganga me te paipa koranu ātete wera pehanga teitei. He rerekē te nuinga i ngā paerewa whakaputa me te ahumahi o ngā paipa koranu, ka rerekē ngā āhuatanga miihini o ngā paipa koranu kua whakamahanahia me te whakamātao. Ka tutuki i ngā tikanga tukatuka e hiahiatia ana. He teitei ake tana mahi i te paipa rino kore hononga noa, he nui ake te Cr i roto i te hanganga matū, nō reira he ātete pāmahana teitei, he ātete pāmahana iti me te ātete waikura. Kāore he wāhanga koranu i roto i ngā paipa koranu kore hononga waro noa, he iti noa rānei ngā wāhanga koranu kei roto. He whānuitia te whakamahinga o ngā paipa koranu i roto i te hinu, te rererangi, te matū, te hiko, te poiha, te ope taua me ētahi atu ahumahi, nā te mea he rerekē ngā āhuatanga miihini o ngā paipa koranu, ā, he ngāwari ki te whakarerekē.

Kua wehea ngā rauemi paipa maitai tui ki: 10, 20, 35, 45, 40Mn2, 45Mn2, 27SiMn, 20Cr, 40Cr, 20CrMo, 35CrMo, 38CrMoA1, 50CrV, 30CrMnSi ASTM A500-98.

Ngā paerewa whakatinanatanga o ngā paipa maitai kore-tukino:

3, ngongo maitai korekore o te kōhua ​​pēhanga iti me te reo (GB3087-2008) e whakamahia ana hei hanga i ngā momo hanganga o te paipa mamaoa wera rawa mō ngā pōro pēhanga iti me te waenga, te paipa wai kohua me te paipa mamaoa wera rawa mō ngā pōro tereina me te paipa pereki āwhata i hangaia ki te maitai hanganga waro kounga teitei kua hurihia wera me te ngongo maitai kumea matao (hurihuri).

4, ngongo maitai korekore o te kōhua ​​pēhanga teitei (GB5310-2008) e whakamahia ana mō te hanga i te mata whakamahana paipa ngongo wai pēhanga teitei me runga ake i te pēhanga me te maitai waro kounga teitei, te maitai koranu me te maitai kowiri tira ātete wera kore-ira.

5, taputapu tongi matū mō te paipa maitai kore-whakarewa pēhanga teitei (GB6479-2000) he pai mō te pāmahana mahi o te -40~400℃, te pēhanga mahi o ngā taputapu matū 10~30Ma me te paipa i hangaia ki te maitai hanganga waro kounga teitei me te maitai koranu he paipa maitai tui kore.

6, paipa maitai kore-whakarewa e pakaru ana i te hinu (GB9948-2006) he pai mō te ngongo oumu o te whare whakapai hinu, te whakawhiti wera me te paipa maitai tui kore.
E ai ki te matotoru o ngā rauemi paipa maitai koranu, ka taea te wehewehe i ngā whakatakotoranga ki 12-42CrMO, T91, 30CrMo, 20G, 15CrMoV, Cr9Mo, 27SiMn, 10CrMo910, 15Mo3, 35CrMoV, 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 16Mn 12Cr1MoV, 50Cr, 15CrMo, 45CrNiMo, me ētahi atu.
