ship plates of middle thickness

Instruction:

The rules of classification society: CCS, ABS, GL, BV, DNV, NK, KR, LR, RINA

ship plates of middle thickness is according to the minimum yield point division strength level for: general strength structural steel and high strength structural steel. According to the classification society is presented.the refers to the construction of the request is used in the manufacturing of the hull structure of the hot rolled steel plate. China classification society standards general strength structural steel is divided into: A, B, D, E four quality level (i.e. CCSA, CCSB, CCSC, CCSD); China classification society standards high strength structural steel for three strength level, four quality level.

Details:

General strength hull structure steel is divided into A, B, D, E4 level, the four levels of yield strength of the steel (no less than 235 n/mm ^ 2) and tensile strength (400 ~ 520 n/mm ^ 2), it's just not the same as that of the under different temperature.
High strength hull structure steel according to the classification strength grade of the minimum yield strength, the strength grade and each according to its impact toughness of different level is divided into A, D, E, F4.
A32, D32, E32, F32 the yield strength of not less than 315 n/mm ^ 2, the tensile strength of 440 ~ 570 n/mm ^ 2, A, D, E, F, respectively their respective respectively in 0 ° ~ 20 °, 40 °, 60 ° what can be achieved under the condition of impact toughness;
A36, D36, E36, F36 the yield strength of not less than 355 n/mm ^ 2, the tensile strength of 490 ~ 620 n/mm ^ 2, A, D, E, F,

A40, D40, E40, F40 the yield strength of not less than 390 n/mm ^ 2, the tensile strength of 510 ~ 660 n/mm ^ 2, A, D, E, F, respectively their respective respectively in 0 ° ~ 20 °, 40 °, 60 ° what can be achieved under the condition of impact toughness.

respectively their respective respectively in 0 ° ~ 20 °, 40 °, 60 ° what can be achieved under the condition of impact toughness;

steel plate thickness Steel plate is flat shape, rectangular, directly or by rolling wide strip is cut and become.

According to the steel plate thickness points, sheet steel < 4 mm (the most thin 0.2 mm), thick steel plate 4 ~ sixty mm, very thick steel plate 60 to 115 mm.  ship plates of middle thickness

According to the steel plate rolling points, points of hot and cold rolled. Sheet width is 500 ~ 1500 mm; Thick width is 600 ~ 3000 mm. Sheet according to the type of steel points and ordinary steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet, etc.; According to professional use points, oil drum with board, with enamel 

Thick steel plate steel and steel sheet in the same. In the article, in addition to bridge steel plate, boiler plate, automobile manufacturing steel plate, pressure vessel steel plate and multilayer high pressure vessel steel plate and a variety of thick plate outside, some varieties of steel such as automobile beam steel plate (thick 2.5 ~ 10 mm), decorative pattern plate (thick 2.5 ~ 8 mm), stainless steel, heat-resistant steel varieties such as is the same sheet cross.
