Sharaxaadda darajooyinka birta qabow ee SPCC

1 qeexitaan magac
SPCCasal ahaan wuxuu ahaa heerka Jabbaan (JIS) "isticmaalka guud eexaashi bir ah oo kaarboon qabow ah oo la duubayiyo magaca birta ee xariijinta, hadda waddamo badan ama shirkado badan ayaa si toos ah u isticmaala inay muujiyaan wax soo saarkooda birta la midka ah. Fiiro gaar ah: darajooyin la mid ah waa SPCD (xariiq bir ah oo qabow lagu duubay iyo xariijin bir ah oo loogu talagalay shaabadeynta), SPCE (xariiq bir ah oo qabow lagu duubay iyo xariijin sawir qoto dheer ah), SPCCK\SPCCE, iwm. (birta gaarka ah ee TV-yada), SPCC4D\SPCC8D, iwm. (birta adag, ee loo isticmaalo giraangiraha baaskiillada, iwm.), siday u kala horreeyaan, munaasabado kala duwan.

2 Qaybood
Birta Jabbaan (taxanaha JIS) ee heerka birta qaab-dhismeedka caadiga ah waxay inta badan ka kooban tahay saddex qaybood oo ka mid ah qaybta hore ee maaddada, sida: S (Birta) in birta, F (Ferrum) in birta; qaybta labaad ee qaababka, noocyada, iyo isticmaalka kala duwan, sida P (Saxanka) in saxanka, T (Tuubada) in tuubada, K (Kogu) in qalabka; qaybta saddexaad ee astaamaha tirada, guud ahaan xoogga ugu yar ee la riixo. Guud ahaan xoogga la riixo ee ugu yar. Sida: SS400 - birta ugu horreysa ee S ayaa tiri (Birta), S labaadna wuxuu yiri "qaab-dhismeedka" (Qaab-dhismeedka), 400 xadka hoose ee xoogga la riixo ee 400MPa, xoogga la riixo ee guud ee 400MPa ee birta guud ee qaab-dhismeedka leh xoog la jiido oo ah 400MPa.

Dheeraad ah: SPCC - xaashi bir ah oo kaarboon ah oo qabow lagu duubay iyo xariijin loogu talagalay isticmaalka guud, oo u dhiganta heerka Shiinaha Q195-215A. Xarafka saddexaad C waa soo gaabin loogu talagalay Qabow Qabow. Waxaa loo baahan yahay in la hubiyo in tijaabada jiidista la sameeyo, dhammaadka darajada oo lagu daray T ee SPCCT.

3 kala soocid bir ah
Jabbaansaxan bir ah oo kaarboon qabow ah oo la duubayDarajooyinka khuseeya: SPCC, SPCD, Calaamadaha SPCE: S - bir (Bir), P - saxan (Saxan), C - qabow la duubay (qabow), afaraad C - caadi (caadi), D - shaabadeyn (Sawir), E - heerka sawir-qaadista qoto dheer (Elength)

Xaaladda daaweynta kulaylka: A-Annealed, S-Annealed + Flat, 8-(1/8) adag, 4-(1/4) adag, 2-(1/2) adag, 1-adag.

Heerka waxqabadka sawirka: ZF- loogu talagalay feerka qaybaha leh sawirka ugu adag, HF- loogu talagalay feerka qaybaha leh sawir aad u adag, F- loogu talagalay feerka qaybaha leh sawir adag.

Heerka Dhammaystirka Dusha Sare: D - Madow (duubitaannada waxaa farsameeya mashiinka shiididda ka dibna la toogan karo), B - Dusha Sare ee Iftiinka leh (duubitaannada waxaa farsameeya mashiinka shiididda).

Tayada dusha sare: dusha sare ee dhammaystirka FC-ga oo horumarsan, dusha sare ee dhammaystirka FB-ga oo sarreeya. Xaaladda, xaaladda dhammaystirka dusha sare, qeexidda tayada dusha sare, heerka sawirka (SPCE oo keliya), qeexidda badeecada iyo cabbirka, saxnaanta astaanta (dhumucda iyo/ama ballaca, dhererka, sinnaan la'aanta).
