Hot rolled products of structural steels - Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels
This document specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 150 mm.
The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.

Overview
EN 10025-4:2019/prA1 is a CEN draft amendment to EN 10025-4:2019 covering hot rolled products of structural steels - specifically the technical delivery conditions for thermomechanical rolled weldable fine grain structural steels. The standard applies to flat and long hot-rolled products in thicknesses ≤ 150 mm, and defines the required chemical composition (Tables 1–3) and mechanical properties (Tables 4–6) for the specified grades and qualities. These steels are intended for heavily loaded welded structures operating at ambient and low temperatures (e.g., bridges, flood gates, storage and water supply tanks).
Key topics and requirements
- Scope and product types: Flat and long hot-rolled weldable fine grain structural steels in the thermomechanical rolled condition, thickness up to 150 mm.
- Chemical composition: Defined grade/quality limits are given in the standard’s Tables 1–3 (refer to the standard for exact compositions).
- Mechanical properties: Tensile, yield and impact performance requirements are specified in Tables 4–6 to ensure fine-grain, low-temperature toughness.
- Technical delivery conditions: Requirements for delivery documentation, mill test reports, marking, and traceability to ensure conformity between producer and purchaser.
- Testing and specimen preparation: The amendment (prA1) modifies clause 9.2.3.2 to clarify tensile test-piece preparation: EN ISO 6892-1 applies, and for flat products either full product thickness or half thickness may be used - provided one product surface is retained.
- Weldability and suitability: Emphasis on steels optimized for welding and heavy structural loading with predictable behaviour at ambient and lower temperatures.
Applications and who uses it
- Primary applications: Structural components in bridges, flood gates, storage tanks, water supply tanks and other heavily loaded welded structures where fine grain and low-temperature toughness are required.
- Users:
- Steel manufacturers and mills (product specification and mill test certification)
- Structural engineers and designers (material selection)
- Fabricators and welders (weldability and fabrication guidance)
- Procurement and quality assurance teams (contract specification and acceptance)
- Testing laboratories and certification bodies (mechanical and chemical testing to standards)
Related standards
- EN 10025 series (Parts 1–6) - general delivery conditions and complementary parts for different structural steel types
- EN ISO 6892-1 - tensile testing of metallic materials (referenced for test specimen preparation and method)
EN 10025-4:2019/prA1 is essential when specifying thermomechanically rolled, weldable fine grain steels to ensure consistent chemical and mechanical performance, reliable weldability, and documented conformity for critical structural applications.
