Steel Billets for Earth Moving Machinery
Earth moving machines are heavy and shock loaded. Forged pins, bushings, gears and track parts need strength and wear resistance.
Typical components
- Pins and bushings
- Gears and sprockets
- Track parts
- Heavy shafts
Recommended steel grades
EN19
A widely used chrome-moly steel with good hardenability, toughness and fatigue strength in the quenched and tempered condition.
EN24
A high strength, deep hardening steel with very good toughness, used where heavy sections must harden right through.
SAE 8620
A low carbon Ni-Cr-Mo steel that carburises to a hard surface over a tough core.
EN9
A higher carbon grade for components needing more strength and wear resistance than EN8 allows.
20MnCr5
A manganese-chromium case hardening grade used for automotive and industrial gears.
Choosing the billet
Case hardening grades give a hard surface over a tough core for pins and gears.
Check the billet size chart for sections and weight per metre, and use the weight calculator for any length.
