Ukuthengiswa kwewaranti yomkhiqizi wepayipi lensimbi ye-alloy engu-30CrMo
Ipayipi lensimbi ye-30CrMo ingxubevange inokuqukethwe kwekhabhoni okungu-0.26 ~ 0.34, okuqukethwe kwe-silicon okungu-0.17 ~ 0.37, okuqukethwe kwe-manganese okungu-0.40 ~ 0.70, okuqukethwe kwe-molybdenum okungu-0.15 ~ 0.25, okuqukethwe kwe-chromium okungu-0.80 ~ 1.10. Kukhona kokubili ubudlelwano kanye nomehluko phakathi kwepayipi le-alloy kanye nepayipi elingenamthungo, elingeke lidideke. Ipayipi le-alloy lichazwa njengepayipi lensimbi ngokusho kwempahla yokukhiqiza (okungukuthi impahla). Njengoba igama liphakamisa, iyipayipi eyenziwe nge-alloy; Ipayipi elingenamthungo lichazwa ngokuya ngenqubo yokukhiqiza yepayipi lensimbi (i-seamless seam). Okuhlukile kumapayipi angenamthungo ipayipi elingenamthungo, elihlanganisa ipayipi elishiselwe ngomthungo oqondile kanye nepayipi elivunguzayo. 35CrMo, 16-50mn, 27SiMn, 40Cr, Cr5Mo 12Cr1MoV 12Cr1MoVG 15CrMo 15CrMoG 15CrMoV 13CrMo44 T91 27SiMn 25CrMo 12CrMoVG 12Cr1MoVG 15CrMo 15CrMoG 15CrMoV 13CrMo44 T91 27SiMn 25CrMo 25CrMo 40CrMo 30CrMo 30CrMo 30CrMo 30CrMo 30Cr3 P22.p91.

Ibanga lensimbi, elifushanisiwe njengebanga lensimbi, igama lomkhiqizo othile wensimbi ngamunye. Kuwulimi olujwayelekile ukuthi abantu baqonde insimbi. E-China, uphawu oluqinile ngokuvamile luvezwa inhlanganisela yezinhlamvu zesiShayina ze-Pinyin, izimpawu zamakhemikhali kanye nezinombolo zesi-Arabhu.
Okulandelayo, sizokwethula incazelo yezakhi nezimpawu ensimbi ye-alloy
Amadijithi amabili ekuqaleni kwebanga lensimbi amelela okuqukethwe kwekhabhoni yensimbi, evezwa njengezinkulungwane ezimbalwa zesilinganiso sokuqukethwe kwekhabhoni, okufana no-40Cr.
Izakhi eziyinhloko ze-alloying ensimbi, ngaphandle kwezakhi ze-microalloyed ngayinye, ngokuvamile zivezwa ngamaphesenti ambalwa. Lapho isilinganiso sokuqukethwe kwe-alloy singaphansi kuka-1.5%, ebangeni lensimbi
Ngokuvamile, uphawu lwe-elementi kuphela olumakiwe, kodwa okuqukethwe akumakwa. Kodwa-ke, uma kulula ukudideka ngaphansi kwezimo ezikhethekile, inombolo "1" ingamakwa ngemuva kophawu lwesici,
Isibonelo, kumamaki ensimbi "12CrMoV" kanye "12Cr1MoV", okuqukethwe kwe-chromium yangaphambili ngu-0.4-0.6%, futhi lokho kokugcina kungu-0.9-1.2%, kanti ezinye izingxenye ziyafana.
Lapho okuqukethwe okumaphakathi kwezakhi ze-alloy kungu-≥ 1.5%, ≥ 2.5%, ≥ 3.5%... Okuqukethwe kuzokhonjiswa ngemva kophawu lwesici, olungavezwa njengo-2 no-3 ngokufanele.

Njll. Isibonelo, i-18Cr2Ni4WA.
I-Vanadium V, i-titanium Ti, i-aluminium Al, i-boron B, umhlaba ongavamile RE kanye nezinye izakhi ze-alloy ensimbi ziyingxenye ye-microalloyed elements. Nakuba okuqukethwe kuphansi kakhulu, kufanele kube sezingeni lensimbi
Maka. Isibonelo, ku-20mnvb steel, i-vanadium ingu-0.07-0.12% futhi i-boron ingu-0.001-0.005%.
Insimbi yekhwalithi ephezulu izomakwa ngo-"a" ekupheleni kwebanga lensimbi ukuze ihlukanise nensimbi evamile yekhwalithi ephezulu.
Ngensimbi yesakhiwo se-alloy ngenjongo ekhethekile, ibanga lensimbi landulelwa (noma isijobelelo) ukumela uphawu lwenjongo yensimbi. Isibonelo, insimbi engu-30CrMnSi yesikulufu se-riveting,
Ibanga lensimbi likhonjiswe njenge-ml30crmnsi.
Ngensimbi esezingeni eliphansi ye-alloy ephezulu, izokhonjiswa ekupheleni kwebanga lensimbi. Isibonelo, insimbi engu-16Mn, insimbi ekhethekile esetshenziselwa amabhuloho "16Mnq", umusi
Ibanga elikhethekile lensimbi yegirder "16MnL", futhi izinga elikhethekile lensimbi yomkhumbi wengcindezi "16MnR".
