Inconel 738 Hot Rolled Alloy Steel Round Bar
Inconel 738 Hot Rolled Alloy Steel Round Bar
Inconel 738 offers a combination of outstanding high-heat creep-rupture strength and corrosion resistance better than many high-strength superalloys with lower chromium content. Inconel 738 is a nickel-based alloy, vacuum-cast and precipitation-hardened, offering exceptional mechanical properties to 1800°F (982°C). IN-738 holds up to the hot corrosive environments found in the turbine industry.
