1. At present, Wugang ship board has passed the certification of French BV, British LR, American ABS, German GL, Norwegian DNV, Italian RINA, Japan NK, China CCS, South Korea KR and other multi-national classification societies. FH32-Z15 is a high strength ship plate with Z-direction properties. Among them, F represents the quality grade of the steel plate, H represents the high strength steel plate, and 32 represents the compressive value. Users can add the Z-direction performance of FH32 ship plate according to the actual use needs. FH32-Z15, FH32-Z25, FH32-Z35, etc. At the same time, FH32-Z15 steel plate can be certified by classification society as required.
2, EH40 ship board implementation standard: GB/T712-2011
3, FH32-Z15 steel plate delivery status: normalizing or according to user needs to negotiate
4, FH32 yield strength is not less than 315N/mm^2, tensile strength 440 ~ 570N/mm^2. A, D, E and F in the ship plate respectively represent the impact toughness that can be achieved at 0°, -20°, -40° and -60° respectively.
5, FH32-Z15 steel plate quality certification review:
Steel factory delivery must be in accordance with the requirements of the user in accordance with the contract specifications and provide the original quality certificate. The certificate contains the following contents:
(1) Standard requirements;
(2) Quality record number and certificate number;
(3) Batch number, technical grade;
(4) chemical composition and mechanical properties;
(5) Certification of classification society and signature of surveyor.
6, FH32-Z15 steel plate physical review:
The delivery of Marine steel, the physical object should be the manufacturer's logo. The details are:
(1) Classification society approved mark;
(2) Paint frame or paste marks, including technical parameters such as: batch number, standard grade, length and width size, etc.;
(3) The appearance is smooth and smooth, without defects.
