The 4 Main Families of Steel
Steel is an alloy of iron and carbon, but small additions of other elements drastically change its behaviour. Click a card to view typical traits and subgroups.
Carbon Steel
Accounts for 90% of total production. Divided into Low, Medium, and High carbon grades.
Alloy Steel
Contains Mn, Si, Ni, Ti, Cu, Cr, or Al to enhance mechanical properties.
Stainless Steel
Contains at least 10.5% Chromium. Provides exceptional corrosion resistance.
Tool Steel
Contains W, Mo, Co, V. Extremely hard and heat resistant for industrial tooling.
