CCSDH690 ship plate specifications, structural steel DH690 for ships and marine engineering, CCSDH69

CCSDH690 is a structural steel for marine engineering certified by China Classification Society, which is divided into four quality grades: A, D, E, and F, namely AH690, DH690, EH690, FH690, H is a high-strength building material, and 690 is a lower yield strength.

CCSDH690 ship plate fixed rolling # Wugang Xiangyang #

CCSDH690 default normalizing can also be done according to different needs can also do normalizing + tempering, normalizing + quenching, sizing, hot rolling, 1 probe, 2 probe, 3 probe, etc.,

CCSDH690 steel plate implementation standard: GBT712-2022

This document is applicable to the manufacture of ocean-going, coastal and inland navigation vessels, fishing boats and other hull structures with a thickness of not more than 150 mm and marine engineering structures with a thickness of no more than 250 mm of steel plates, steel strips and shear plates with a thickness of no more than 25,4 mm, section steel with a thickness of no more than 50 mm or bars with a diameter of no more than 50 mm (hereinafter referred to as steel).

Their classification societies are certified as follows:

CCS, USA, ABS, GERMANY, GL, France, BV, Norway, DNV, Japan, NK, UK, LR, Italy, RINA, South Korea KR (Norway, DNV, Germany merged into VL).

CCSDH690 steel plate itself not only has very high strength, but also has a certain toughness, and also carries fatigue resistance, impact resistance, wear resistance, corrosion resistance, welding and easy processing.

CCSDH690 is often used in marine engineering and shipbuilding industry, for example, ship decks, pressure elements, offshore platforms, offshore drilling platforms, offshore drilling head supports, pillars, leg piles, etc.,

the reason why they are so frequently used in the marine machinery and equipment manufacturing industry is because CCSDH690 self-locking has anti-fatigue, impact resistance, welding, easy processing, Wear-resistant, anti-corrosion and other high-quality properties.
