Knowledge base
Reference metallurgy for the grades we work with, compiled from a technical report and held to the same standard as the catalogue: ranges are ranges, caps are caps, and nothing here pretends to be a mill certificate. What we actually stock is flagged on every page; the rest is reference material we can bring in on request.
The lifecycle
How steel is made
Six stages from ore and scrap to the passive film: steelmaking, refining, casting, forming, heat treatment and finishing.
18 alloys
Alloy explorer
Filter the library by family, industry and stock status. Every alloy has a full data sheet with sourced composition and properties.
Side by side
Compare alloys
Put two to four alloys on shared scales: specified composition ranges, PREN windows, performance profile and properties.
Working numbers
Calculators
PREN from chemistry with an explicit nitrogen weighting, unit conversion, and theoretical section weight from stated density.

6 lifecycle stages, 18 alloy records - 6 of them are grades we list on the floor.
This reference is guidance for selecting a grade, not a specification. Design to the governing standard and the mill certificate for the heat you are supplied. Looking for what is on the floor rather than the science? The grade explorer lists only stocked grades.
