ʻO ke kūpaʻa ʻino
Hoʻohālikelike ʻia ka pae maʻamau o ke kūpaʻa corrosion o Type 201 me Type 301's.I ka hapanui o nā kūlana haʻahaʻa, pono e hana maikaʻi ke ʻano 201 ma kahi o ka Type 301. He haʻahaʻa haʻahaʻa ko ke ʻano 201 ma mua o ka Type 301. ʻO ke ʻano 201 ma kahi o 50 °F (28 °C) liʻiliʻi ke kūpaʻa ʻana i ka scaling luku ma mua o Type 301 a hiki i ka 1500 °F (816 °C).
Hana ʻia
E like me Type 301, Type 201 stainless steel hiki ke hana ʻia ma o ka hana ʻana i ka pae, ka ʻōwili ʻana, a me ke kuʻi ʻana.Akā ma muli o kona ikaika nui, ʻoi aku ka nui o ke kua.I ka hapanui o nā hihia, hiki ke huki like ʻia kēia mea me Type 301
inā hoʻohana ʻia ka mana hou aʻe a hoʻokiʻekiʻe ʻia ke kaomi paʻa i lalo, nā hana kaha kiʻi.
Weldability
Ua manaʻo nui ʻia nā kaʻina hana fusion maʻamau a me ke kūpaʻa e hiki ke hoʻohui i nā kila kila i ka papa austenitic.Ma ka hōʻoia ʻana i nā ʻano ferrite i loko o ka waihona weld, pono e mālama pono i ka pale ʻana i ka weld "weld crack".Hiki ke ma'alahi a hiki ke ho'opa'a 'ia ka weld weld i ka corrosion intergranular ma kekahi mau 'ano, e like me nā māka kila kuhili 'ole chrome-nickel austenitic kahi i mālama 'ole 'ia ai ke kalapona i ka 0.03% a emi mai paha.Ke hoʻohālikelike ʻia me ka Type 304L Stainless Steel, ʻo ia ka mea i kaulana loa i loko o kēia papa stainless, ʻoi aku ka maikaʻi o ka weldability o kēia alloy.ʻO ka ʻōlelo kikoʻī maʻamau no AWS E/ER 308 ke koi ʻia kahi hoʻopiha weld.Hiki ke loaʻa nā kikoʻī hou aʻe ma ka palapala kuhikuhi, kahi i kaulana no ka Type 201 Stainless Steel.
Hoʻoponopono wela
ʻAʻole hiki ke paʻakikī ke ʻano 201 e ka mālama wela.Hoʻohui: Anneal ma 1850 – 1950 °F (1010 – 1066 °C), a laila e kinai i ka wai a i ʻole e hoʻolili koke i ka ea.Pono e mālama ʻia ka mahana annealing ma kahi haʻahaʻa e like me ka hiki, e kūlike me nā waiwai i makemake ʻia, no ka mea, ʻoi aku ka nui o ka Type 201 ma mua o ka Type 301
