Steels and alloys for internal combustion engine valves
Creep-resistant steels and alloys

Definitions

Valve materials are steels and non-ferrous metal alloys with varying degrees of resistance to the following phenomena:

• heat ;

• thermal cycle ;

• corrosion ;

• oxidation ;

• fatigue ;

• impact bending ;

• wear through friction and abrasion.

Given these characteristics, these materials are used...
