42CRMO Umbhobho wentsimbi ongenamthungo
Injongo ye-42crmo ipayipi yensimbi engenamthungo: Ibakala elikhethekileyo lensimbi yeebhulorho "42crmo", ibakala elikhethekileyo lentsimbi yeegidi zemoto yi "42CRmo", kwaye ibakala elikhethekileyo lentsimbi kwiinqanawa zoxinzelelo "42Crmo".Olu hlobo lwensimbi luxhomekeke ekulungiseni umxholo wekhabhoni (C) ukuphucula iimpawu zomatshini zentsimbi.Ngoko ke, ngokwezinga lomxholo wekhabhoni, olu hlobo lwensimbi lunokwahlulwa lube: Intsimbi ye-carbon ephantsi-i-carbon content ngokuqhelekileyo ingaphantsi kwe-0.25%, njenge-10, i-20 yensimbi, njl.;umxholo we-carbon steel-carbon content ngokubanzi phakathi kwe-0.25 kunye ne-0.60%, njenge-35, i-45 yensimbi, njl.;umgangatho ophezulu we-carbon steel-carbon umxholo ungaphezulu kwe-0.60%.Olu hlobo lwentsimbi alusetyenziswanga ngokubanzi ekwenzeni imibhobho yentsimbi.
Akukho msindo ocacileyo ocacileyo, ukuguqulwa okuncinci ngexesha lokucima, umda wokudinwa okuphezulu kunye nokumelana neempembelelo ezininzi emva kokucinywa kunye nonyango olushushu, ukuqina kwefuthe eliphantsi lobushushu obuphantsi, amandla aphezulu ahambahambayo kunye namandla ahlala ixesha elide kwiqondo lokushisa eliphezulu.Intsimbi ngokuqhelekileyo isebenzisa ukucima umphezulu emva kokucima kunye nokufudumala njengesicwangciso sonyango lobushushu.
I-42crmo yimathiriyeli kwintsimbi.Ngaphambili, igama lentsimbi.Igama li: Q345B, izinto ezifanayo yi-Q345a, Q345c, Q345e, uphawu lwebakala lomgangatho ABCDE lithetha ukuba ubushushu bovavanyo lwempembelelo ayidingekiyo ukuba bube +20 degrees 0 degrees -20 degrees 40 degrees ABCD imele umgangatho womgangatho Q235 amanqaku omgangatho Kukho amanqanaba amane A, B, C, D, ukusuka ku-A ukuya ku-D ukuba umgangatho usuka kwi-low ukuya phezulu.
Iimfuno zamanqanaba ahlukeneyo omgangatho zezi zilandelayo:
A——Nika ukwakheka kweekhemikhali ze-S, P, C, Mn, Si kunye ne-fu, fy, δ5 (δ10), ngokweemfuno zomthengi, uvavanyo lwe-gold bend lwe-1800 lunokunikezelwa, kodwa akukho mpembelelo yokulawula amandla, ikhabhoni. umxholo kunye nomxholo wemanganese awuthathwa njengemiqathango yokuhanjiswa.
B——Nika i-S, P, C, Mn, Si ukwakheka kweekhemikhali kunye ne-fu, fy, δ5 (δ10), ukugoba okubandayo 180' uvavanyo.Ikwabonelela ngamandla empembelelo kwi +200C, Ak≥27J
C-Ukongezelela kwiimfuno ezifanayo njengeKlasi B, inika kwakhona amandla empembelelo Ak≥27J kwi-00C.
D---- Ukongeza kwiimfuno zenqanaba B, ikwabonelela ngamandla empembelelo Ak≥27J kwi -200C.E---- Ukongeza kwiimfuno zenqanaba B, ikwabonelela ngamandla empembelelo Ak≥27J kwi -400C.
Apho i-42crmo imibhobho yentsimbi engenamthungo kunye nemibhobho yentsimbi eqhelekileyo isetyenziswa ngokulandelelanayo: Imibhobho yentsimbi yahlulwe yaba yingqele ezotyiweyo kunye neshushu esongwayo.
