1. Bir loogu talagalay qaab dhismeedka hull xoogga guud
Birta xoogga guud ee qaab dhismeedka hull waxa loo qaybiyaa afar darajo: A, B, D iyo E 520N/mm^2). , laakiin awoodda saamaynta ee heerkulka kala duwan ayaa ka duwan;
Biraha qaab-dhismeedku waxay u qaybsan yihiin darajooyin xoog leh iyadoo loo eegayo awoodda wax-soosaarka ugu yar, iyo darajo kasta oo xoog leh ayaa loo qaybiyaa darajooyinka A, D, E, F4 iyadoo loo eegayo adkaanta saameynteeda.
Awoodda wax-soo-saarka ee A32, D32, E32, iyo F32 kama yarayn 315N/mm^2, xoogga xajintuna waa 440-570N/mm^2. Saamaynta adag ee lagu gaari karo -40 °, -60 °;
Awoodda wax-soo-saarka ee A36, D36, E36 iyo F36 kama yarayn 355N/mm^2, xoogga xajintuna waa 490～620N/mm^2. Saamaynta adag ee lagu gaari karo -40 °, -60 °;
Awoodda wax-soo-saarka ee A40, D40, E40, iyo F40 kama yara 390N/mm^2, xoogga xajintuna waa 510~660N/mm^2. Saamaynta adag ee lagu gaari karo -40 ° iyo -60 °.
ka sokow,
Awood sare oo la demiyo iyo bir dabcay oo loogu talagalay qaab dhismeedka alxanka: A420, D420, E420, F420; A460, D460, E460, F460; A500, D500, E500, F500; A550, D550, E550, F550; A620, D620, E620, F620; A690, D690, E690, F690;
