3CR13 kila poepoe kuhilihi
3Cr13 kuhiliʻole kila paipu kila maʻamau:
ʻO GB / T1220-1992, he kila kila martensitic, he hana machining maikaʻi kēia kila, ma hope o ka mālama ʻana i ka wela (quenching and tempering), maikaʻi loa ke kūpaʻa corrosion, hana polishing, ikaika kiʻekiʻe a hoʻopaʻa i ka wahine.
Kūlana: GB/T 1220-2007
ʻO ka hōʻailona Iapana kūpono: SUS420JI
E pili ana i ka hōʻailona Kelemania: X20Cr13/1.4021
E pili ana i ka hōʻailona ʻAmelika: 420
Wahi a ke kaʻina hana, hiki ke hoʻokaʻawale ʻia ke kila kila kila i ʻekolu mau ʻano: ʻōwili wela, paʻa a huki ʻia ke anu.ʻO nā kikoʻī o nā kaola pōʻai kila kila wela he 5.5-250 mm.I waena o lākou: ʻo nā kīʻaha kila kila liʻiliʻi o 5.5-25 mm ka hapa nui i hoʻolako ʻia i loko o nā pūʻulu o nā kaola pololei, i hoʻohana pinepine ʻia e like me nā pahu kila, nā bolts a me nā ʻāpana mechanical like ʻole;'Oi aku ka nui ma mua o 25 mm, ua ho'ohana 'ia nā 'āpana mechanical a i 'ole nā paipu paipu kila..
Kūlana hoʻouna:ʻO ka mea maʻamau, aia ka hāʻawi ʻana i ke kūlana mālama wela, a hōʻike ʻia ke ʻano o ka mālama wela ma ka ʻaelike;inā ʻaʻole i hōʻike ʻia, aia ka hāʻawi ʻana i ke kūlana mālama wela ʻole.
