2022 Good Quality Carbon Steel Plate - Shipping building material miedum thickness steel plate – Ruigang Detail:
Ship class specification
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 yield point: general-strength structural steel and high-strength structural steel. 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.
Introduction to ship plate
1. Steel for general strength hull structure
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). , but the impact power at different temperatures is different;
High-strength hull structural steel is divided into strength grades according to its minimum yield strength, and each strength grade is divided into A, D, E, F4 grades according to its impact toughness.
The yield strength of A32, D32, E32, and F32 is not less than 315N/mm^2, and the tensile strength is 440-570N/mm^2. Impact toughness that can be achieved at -40°, -60°;
The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the tensile strength is 490～620N/mm^2. Impact toughness that can be achieved at -40°, -60°;
The yield strength of A40, D40, E40, and F40 is not less than 390N/mm^2, and the tensile strength is 510~660N/mm^2. The impact toughness that can be achieved at -40° and -60°.
besides,
High-strength quenched and tempered steel for welded structure: A420, D420, E420, F420; A460, D460, E460, F460; A500, D500, E500, F500; A550, D550, E550, F550; A620, D620, E620, F620; A690, D690, E690, F690;
Steel for boilers and pressure vessels: 360A, 360B; 410A, 410B; 460A, 460B; 490A, 490B; 1Cr0.5Mo, 2.25Cr1Mo
Steel for mechanical structure: Generally, the above steel can be used;
Low temperature toughness steel: 0.5NiA, 0.5NiB, 1.5Ni, 3.5Ni, 5Ni, 9Ni;
Austenitic stainless steel: 00Cr18Ni10, 00Cr18Ni10N, 00Cr17Ni14Mo2, 00Cr17Ni13Mo2N, 00Cr19Ni13Mo3, 00Cr19Ni13Mo3N, 0Cr18Ni11Nb;
Duplex stainless steel: 00Cr22Ni5Mo3N, 00Cr25Ni6Mo3Cu, 00Cr25Ni7Mo4N3.
Clad steel plate: suitable for containers and cargo tanks of chemical carriers;
Z-direction steel: It is a steel that has undergone special treatment (such as calcium treatment, vacuum degassing, argon stirring, etc.) and appropriate heat treatment on the basis of a certain grade of structural steel (called parent steel).
