Kunyanya nekuda kweakasiyana kabhoni uye manganese zvirimo:
Q235-A
Carbon content C: 0.14 ~ 0.22; Mn: 0.30 ~ 0.65;
Q235-B
Carbon content C: 0.12 ~ 0.20; Mn: 0.30 ~ 0.70;
Iyo inoshandiswa kune carburized kana cyanide zvikamu zvine yakaderera musimboti simba zvinodiwa, senge kudhonza tsvimbo, yekubatanidza tsvimbo, hoko, bhaudhi, shaft uye weldment.
Panofanira kuva nezvirambidzo pakupisa!
Kunyanya Q345E. Makumi emadhigirii pasi pe zero.
Mukuwedzera, kana zvichienzaniswa nechiyero chekare, chinonyanya kudiwa chechiyero chitsva ndechekugadzirisa Mn zvinyorwa musimbi kubva 1.0-1.60 kusvika ≤ 1.70, uye kudzima iyo shoma kukosha muganho we ≥ 1.0.
Q345C simbi pombi chimwe chezvinhu zvesimbi pombi.
Q345A, Q345B, Q345C, Q345D uye Q345E ndiwo mamakisi emhando. Ivo vanowedzera kubva ku a kuenda ku e, kunyanya nekuda kwekusiyana kwekupisa tembiricha kunokonzerwa nezvakasiyana zvemukati ma microelements senge phosphorus nesarufa, inomiririra mutsauko wekukanganisa tembiricha uye michina zvimiro zvepombi kemikari.
Q345A, hapana kukanganisa; Q345B, 20 ° yakajairika tembiricha kukanganisa; Q345C, 0 dhigirii kukanganisa; Q345D, iri - 20 dhigirii kukanganisa; Q345E iri - 40 dhigirii kukanganisa. Pamhando dzakasiyana dzetembiricha, kukosha kwemaitiro kwakasiyanawo.
Q simba regoho harina kuderera kupfuura 345mp, uye giredhi yemhando inoratidza kuti ine zvinhu zvisina kuchena (carbon, manganese, silicon, sulfur uye phosphorus). Kuwanda kwetsvina (elements) musimbi. Iyo yakazotevera iyo A, B, C uye D, ishoma iyo isina kuchena yemukati
Q345A ine zvese phosphorus nesarufa isingasviki kana yakaenzana ne0.045%
Q345B ine zvese phosphorus nesarufa isingasviki kana yakaenzana ne0.040%
Q345C ine zvese phosphorus nesarufa isingasviki kana kuenzana ne0.035%
Q345D ine zvese phosphorus nesarufa isingasviki kana kuenzana ne0.030%
Q345E ine zvese phosphorus nesarufa isingasviki kana yakaenzana ne0.025%
Kunyanya kusvibiswa kwephosphorus nesarufa musimbi, ndiko kunowedzera kuoma kwesimba

Q345B Akv kwete pasi pe34 pa20 ℃
PaQ345C 0 ℃, Akv haifanire kunge iri pasi pe34
Q345D - Akv isiri pasi pe34 pa20 ℃
PaQ345E - 40 ℃, Akv haisi pasi pe27
Chikonzero chekupedzisira ndechekuti kudzikiswa kweP uye s tsvina musimbi inosimudzira kuvandudzwa kwekuoma kwesimba pakupisa kwakadzika. Imwe ndiyo kemikari yeQ345 uye imwe yacho ndeye mechanical properties yeQ345
