Martensitic creep-resisting steel 1.4938 hardened round bar, flat bar, stock available ESR steel ingot 1.4938 heat treated, peeled
Steel 1.4938 is defined as a high-alloy content of 12.0%Cr - 3.0% Ni - 2.0% Mo steel with the addition of vanadium for carburization with a martensitic structure,
1.4938 provides high strength properties and significantly increased resistance to oxidation. The grade is used for the production of aviation propellers, especially loaded gears, ball screws, responsible parts working at elevated temperatures.
