EN 15774 Stainless Steel Scrap Characterization
The European Standard EN 15774 provides a robust framework for characterizing stainless steel scrap. This standard is essential for ensuring the quality and consistency of stainless steel recycling, which plays a significant role in sustainable manufacturing processes.
Stainless steel scrap characterization involves assessing various properties that determine its suitability for recycling into new products. The process includes evaluating chemical composition, mechanical properties, surface condition, and other relevant factors. Proper characterization ensures that recycled material meets the required standards for downstream applications such as fabrication of new parts or components.
The first step in this process is obtaining a representative sample from the scrap lot. This involves cutting pieces to ensure homogeneity across the batch. Once samples are collected, they undergo rigorous testing according to EN 15774 guidelines. Key tests include:
- Chemical composition analysis using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)
- Mechanical property evaluation through tensile testing
- Surface inspection for contamination or damage with optical microscopy
- Electrical resistivity measurement to assess purity levels
- Microstructural examination via scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS)
These tests provide comprehensive data on the scrap’s quality, allowing manufacturers to make informed decisions about how best to utilize it. For instance, higher purity grades might be used for food contact applications while lower grade materials could go into construction projects where durability is more critical than purity.
The results of these analyses are then summarized in a detailed report that includes all test findings along with recommendations for optimal processing methods based on the scrap’s characteristics. This information helps ensure compliance with relevant regulations and ensures consistent product quality throughout the supply chain.
Accurate characterization is particularly important because stainless steel scrap can vary widely depending on its origin, usage history, and environmental exposure. By adhering strictly to EN 15774 procedures, laboratories like ours guarantee accurate assessments that reflect true material properties rather than potential discrepancies arising from poor sampling practices or outdated methods.

Applied Standards
The primary standard applied during EN 15774 Stainless Steel Scrap Characterization is the European Standard itself - EN 15774: Metallic scrap — Chemical, mechanical and physical properties of stainless steel scrap and ferroalloys for recycling. This document specifies the criteria needed to assess various aspects of stainless steel scrap including:
- Chemical composition limits
- Mechanical performance requirements
- Purity levels acceptable for different applications
- Surface quality standards
- Evaluations of any contaminants present in the material
In addition to EN 15774, other relevant international standards may also be referenced depending on specific project requirements or regional preferences. These include:
- ASTM A380/A380M-21: Standard Specification for Ferroalloys
- ISO 9001: Quality Management Systems Requirements
- IEC 61439-1: Technical requirements for electrical installations in buildings
By incorporating multiple standards into our testing protocols, we ensure that every aspect of the scrap is thoroughly evaluated against internationally recognized benchmarks.
