steel_strength_v1-1

A tabular dataset of elemental compositions and mechanical properties for 312 steel alloys to support alloy design.

What steel_strength_v1-1 is

steel_strength_v1-1 provides chemical compositions and measured mechanical properties for 312 steel alloys. Compiled by Gareth Conduit and distributed through the Materials Data Facility and Foundry-ML, the collection pairs elemental weight concentrations with key mechanical performance metrics.

The dataset addresses the requirement for structured composition–property pairs in engineering and materials science, particularly for machine learning workflows targeted at high-strength alloy discovery and mechanical property estimation.

How it was made

The data is structured as tabular entries where each row corresponds to an individual steel alloy.

The targets comprise three experimentally measured mechanical properties: yield strength in megapascals (MPa), tensile strength in megapascals (MPa), and elongation at fracture as a percentage. All records are provided in a single training split.

Strengths and limits

Good at

  • Provides simultaneous measurements of yield strength, tensile strength, and elongation alongside complete compositional profiles.
  • Pre-formatted for straightforward integration into tabular regression and classification pipelines.

Watch out for

  • The dataset is limited in scale to 312 alloy records.
  • All entries reside in a single train split without standard validation or test partitions.
  • Thermal histories, heat treatments, and microstructural parameters are not included in the feature set.

Questions
