Steel and castings for the energy sector

We supply alloy steels, forged steel and castings for turbine and gearbox shafts, flanges, pump and valve bodies and wear parts.

Material Selection

Which part, which material?

Energy equipment runs for long periods without stopping, under changing loads and often in abrasive or corrosive conditions. That is why alloy steels that stay tough even in large sections, and casting materials suited to the application, are the main choices.

Turbine, generator and gearbox shafts

Material group

Quenched and tempered steels

Deep hardening and high toughness in large sections.

Example grades

34CrNiMo6 (SAE 4340)42CrMo4 (SAE 4140)

Part

Gearbox gears

Material group

Case-hardening steels

Hard surface and tough core for heavily loaded gears.
