Haynes® 230® Alloy

UNS N06230
W.Nr 2.4733

Applications

Catalyst grid supports, gas turbine components, high temperature bellows, furnace components.

Description

Haynes® 230® alloy is a nickel-chromium-tungsten-molybdenum alloy which combines excellent high temperature strength and oxidation resistance with superior long term stability and good fabricability. It has lower thermal expansion characteristics than most high temperature alloys and resists grain coarsening with prolonged high temperature exposure.
