ABS Grade FH40 Shipbuilding Steel

High-strength marine-grade shipbuilding steel engineered for long service life in offshore and naval applications. ABS Grade FH40 is a 400 MPa class, high-tensile ship plate designed for hulls, offshore platforms, pipe joints and repair work where superior structural strength and toughness are required.

Key features and benefits:

• High yield strength: FH40 corresponds to a 400 MPa-class F-grade marine steel (suitable for heavy structural applications).
• Marine certification options: available to ship classification standards including ABS, LR, GL, DNV, BV, NK, KR, RINA and CCS.
• Large stock and fast supply: over 10,000 tonnes of hot-rolled and cold-rolled ABS/FH40 material in stock for prompt delivery; production lead time 10–40 days when out of stock.
• On-demand processing services: precision cutting to any size/shape, drilling, welding, milling and machining to customer specifications—reduces downstream fabrication time and cost.
• Traceability and documentation: Mill Test Certificates (MTC) available.

Typical applications:

• Ship hulls and superstructures
• Offshore oil & gas drilling platforms and rigs
• Platform pipe joints and structural components
• Ship repair and retrofits
