Production Process and Quality Control of ABS Grade D Marine Steel Plates

The production process of ABS Grade D marine steel plates directly determines their performance stability and quality reliability. As a key structural material in shipbuilding, the production process must strictly adhere to ABS specifications and relevant international standards. From raw material selection, smelting and rolling to heat treatment and inspection, every stage requires precise control to avoid issues such as compositional deviations, substandard performance and surface defects. This article systematically outlines the core production processes for ABS Grade D steel plates and breaks down the key quality control points at each stage, providing a technical reference for manufacturers and purchasers to ensure the material meets the stringent requirements of shipbuilding.

Comparison of ABS Grade B marine steel plates with equivalent-grade steel plates from BV, DNV and CCS

In shipbuilding, in addition to ABS Grade B marine steel plates certified by the American Bureau of Shipping (ABS), organisations such as Bureau Veritas (BV), Det Norske Veritas (DNV) and the China Classification Society (CCS) have also certified steel plates of the same grade. These steel plates are all classified as general-purpose shipbuilding steel plates, but there are subtle differences in their standard requirements, performance specifications and applications.
