(Amendment)Hot rolled and cold rolled non-coated products of multiphase steels for cold forming - Technical delivery conditions
General Information
- Abstract
This document applies to hot rolled and cold rolled non-coated steel flat products made of multiphase steels for cold forming. It covers cold rolled products of thicknesses t < 3 mm and hot rolled products of thicknesses t ≤ 6,5 mm.
These products are delivered in sheet, hot rolled strip, slit hot rolled strip, cold strip, slit cold rolled strip or cut lengths obtained from slit wide strip.
Flat products of multiphase steels for cold forming can be delivered with an electrolytic zinc coating according to EN 10152.

Overview
EN 10338:2025/prA1 is a draft European Standard developed by CEN that specifies the technical delivery conditions for hot rolled and cold rolled non-coated flat steel products made from multiphase steels intended for cold forming. These products are available as sheets, strips (hot and cold rolled), slit strips, and cut lengths from slit wide strips. The standard covers:
- Cold rolled steel products with thicknesses less than 3 mm
- Hot rolled steel products with thicknesses up to 6.5 mm
This amendment addresses updates to normative references, mechanical properties, and mechanical testing requirements, supporting manufacturers and end-users in ensuring product quality, consistency, and compliance across Europe.
Key Topics
EN 10338:2025/prA1 focuses on several crucial aspects of non-coated multiphase steels for cold forming:
- Product Scope: Applies to flat products without a coating, intended for cold forming applications.
- Product Forms: Includes sheets, hot rolled strips, slit hot rolled strips, cold strips, slit cold rolled strips, and cut lengths.
- Material Thickness: Specifies thicknesses for cold rolled (<3 mm) and hot rolled (≤6.5 mm) products.
- Technical Amendments:
- Updated normative references, including the addition of EN 10373 for the determination of physical and mechanical properties using models.
- Updated steel numbering to ensure precision and traceability.
- Revised instructions on mechanical testing. The manufacturer may determine mechanical properties unless otherwise agreed upon during ordering, with provisions for calculation in line with EN 10373.
- Delivery Conditions: Technical conditions designed to standardize delivery and ensure reliable performance during subsequent cold forming operations.
Applications
This standard is highly relevant for industries and manufacturers involved in:
- Automotive Manufacturing: High strength, formable steels for body panels, structural components, and crash-resistant parts.
- Domestic Appliances: Multipurpose steel sheets and strips for appliance casings and internal structures where cold forming is essential.
- Construction: Structural elements and façade components requiring precise flatness and reliable mechanical properties.
- Industrial Equipment: Machinery parts benefitting from the ductility and strength characteristics of multiphase steels.
- Steel Service Centers: Ensures consistent supply and traceability for downstream forming and fabrication processes.
EN 10338 defines clear requirements for product quality and mechanical properties, optimizing the production processes, minimizing variation, and facilitating specification compliance for clients.
Related Standards
Several European standards are closely related to EN 10338:2025/prA1, providing a comprehensive framework for the assessment, delivery, and processing of steel flat products:
- EN 10152: Specifies requirements for electrolytically zinc-coated flat products, which can also be supplied as multiphase steels for cold forming.
- EN 10373: Methodology for determining the physical and mechanical properties of steels using models-a new addition referenced in this amendment.
- EN 10025 series: Covers hot rolled products of structural steels.
- EN 10268: Pertains to cold-rolled steel flat products for cold forming.
Adherence to these standards helps industry professionals achieve greater interoperability, product consistency, and supply chain efficiency in the European and global steel market.
By aligning technical specifications and delivery conditions through EN 10338:2025/prA1, manufacturers and users of flat multiphase steels for cold forming can ensure high-quality output, reliable mechanical performance, and compliance with European best practices for steel product supply.
