N-155

Verifiedmetal

N-155 is a cobalt-based superalloy containing chromium, aluminum, and tungsten, designed for high-temperature structural applications in jet engines and gas turbines requiring strength retention above 1000°C. The solution-treated condition provides optimal strength and creep resistance through controlled precipitation hardening, with excellent oxidation resistance and fatigue performance in extreme thermal cycling environments.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
