The main classification society specifications are: China CCS, American ABS, German GL, French BV, Norway DNV, Japan NK, British LR, South Korea KR, Italy RINAThe hot-rolled steel strip for ships is divided into strength grades according to its minimum Barta dhalida: Birta qaab-dhismeedka guud ee xoolaha iyo birta qaab-dhismeedka sare leh. Ship plate refers to the hot-rolled plate produced in accordance with the requirements of the construction rules of classification societies for the manufacture of ship hull structures.

Hordhac saxanka maraakiibta

1. Birta si guud ee loo yaqaan 'Hull'

The general strength steel for hull structure is divided into four grades: A, B, D and E. The yield strength (not less than 235N/mm^2) of these four grades of steel is the same as the tensile strength (400～ 520n / mm ^ 2). , laakiin awoodda saameynta ee heerkulka kaladuwan ayaa ka duwan;

Xoogga dhalinta ee A32, D32, E32, iyo F32 ma aha wax aan ka yarayn 315n / mm ^ 2, iyo xoogga jilicsan waa 440-570n / mm ^ 2. Saamaynta adkeynta ee lagu gaari karo -40 °, -60 °;

Xoogga dhalidda ee A36, D36, E36 iyo F36 ma aha wax aan ka yarayn 355n / mm ^ 2, iyo xoogga jilicsan waa 490 ~ 620n / mm ^ 2. Saamaynta adkeynta ee lagu gaari karo -40 °, -60 °;

Xoogga dhalidda ee A40, D40, E40, iyo F40 ma aha wax ka yar 390n / mm ^ 2, iyo xoogga jilicsan waa 510 ~ 660n / mm ^ 2. Saamaynta adag ee lagu gaari karo -40 ° iyo -60 °.

ka sokow,

Iftiisii sare oo jilicsan oo qabow oo loogu talagalay qaab-dhismeedka welleed: A420, D420, E420, F420; A460, D460, E460, F460; A500, D500, E500, F500; A550, D550, E550, F550; A620, D620, E620, F620; A690, D690, E690, F690;

Birta ku jirta kuleyliyaha iyo maraakiibta cadaadiska: 360A, 360b; 410A, 410b; 460A, 460b; 490A, 490B; 1cr0.5mo, 2.25cr1mo

Birta qaab dhismeedka farsamada: Guud ahaan, birta kore waa la isticmaali karaa;

Heerkulka adag ee heerkulka ee yar: 0.5NIB, 0.5NIB, 1.5ni, 3.5mi, 5ni, 9ni;
