Steel and castings for automotive and its suppliers
We supply case-hardening, quenched and tempered, free-cutting and carbon steels used to make gears, shafts, axles and forgings, as well as ductile iron castings.
Which part, which material?
In automotive, cost per part, machinability in volume production and fatigue strength drive material choice. The same vehicle combines case-hardened gears, quenched and tempered axles and forgings with controlled cooling.
Part
Gears, pinions, gearbox shafts
Material group
Case-hardening steels
The surface is carburised and hardened: wear-resistant surface, tough core.
Example grades
Part
Axles, tie rods, heavily loaded shafts
Material group
Quenched and tempered steels
High strength and toughness through hardening and tempering.
Example grades
Part
Forgings such as crankshafts and connecting rods
Material group
Quenched and tempered steels
High strength and fatigue resistance through hardening and tempering after forging.
Example grades
Part
Fasteners, precision turned parts
Material group
Free-cutting steels
Sulphur/lead additions give short chips and high machine speeds.
Example grades
Part
Brackets, hubs and housings
Material group
Ductile iron castings
Higher tensile strength and ductility than grey iron; suited to impact.
