Overview

SIST EN 10338:2025/oprA1:2026 establishes the technical delivery conditions for hot rolled and cold rolled non-coated products of multiphase steels intended for cold forming. Developed by the Slovenian Institute for Standardization (SIST) in alignment with the European standard EN 10338, this document is applicable to steel flat products, including sheets, coils, strips, and cut lengths. Featuring both hot rolled (up to 6.5 mm thickness) and cold rolled (thickness below 3 mm) options, the standard provides a comprehensive framework for quality, testing, and delivery for end-users in industries demanding high-formability multiphase steels.

Key Topics

• Scope of Application

  • Covers hot rolled and cold rolled, non-coated flat steel products made from multiphase steels
  • Product forms: sheet, hot rolled strip, slit hot rolled strip, cold strip, slit cold rolled strip, cut lengths from slit wide strip

• Product Dimensions

  • Cold rolled: thickness less than 3 mm
  • Hot rolled: thickness up to 6.5 mm

• Technical Modifications (Amendment A1)

  • Update to normative references, incorporating EN 10373 for the determination of physical and mechanical properties using models
  • Revision of mechanical property identification for certain steel grades
  • Flexibility in mechanical properties determination, allowing manufacturers discretion unless otherwise specified at the time of order
  • If calculated, mechanical properties must follow EN 10373

Applications

Multipurpose Use Across Key Industries

Flat products made of non-coated multiphase steels are widely employed in sectors where advanced cold forming capabilities and optimized strength-to-weight ratio are critical. Typical applications include:

• Automotive Manufacturing: Body panels, structural reinforcements, and safety elements requiring high energy absorption and formability.
• Appliance & White Goods: Components such as frames, housings, and supports that demand dimensional consistency and precise cold forming.
• Metal Furniture and Equipment: Production of durable and lightweight flat steel products with superior mechanical properties.
• Construction Sectors: Use in partitions, cladding, and fabricated steel components where cold shaping and durability are essential.

Versatility in Supply Formats

Suppliers can provide these multiphase steel products in various forms and dimensions, offering manufacturers the flexibility to select the most suitable input for their cold forming processes. The standard ensures clear technical and quality agreements between steel producers and users, supporting efficient, cost-effective, and high-quality production flows.

Related Standards

For manufacturers and users seeking comprehensive guidance or harmonized specifications concerning flat steel products for cold forming, the following standards are closely related:

• EN 10338 - Base standard on hot rolled and cold rolled non-coated multiphase steels for cold forming
• EN 10152 - Electrolytic zinc-coated cold rolled steel flat products for cold forming
• EN 10373 - Determination of physical and mechanical properties of steels using models (now referenced within SIST EN 10338:2025/oprA1:2026)

Staying up-to-date with these standard references ensures compatibility, regulatory alignment, and integration in broader supply chains across Europe and globally.
