BÖHLER T200
BÖHLER T200 is a corrosion and heat-resistant steel in the form of bars, wire, forgings and stock for forging.
It is an ESR-quality, austenitic precipitation hardenable nickel-chromium-molydenum-titanium steel.
These products have been used typically for such as turbine discs, shafts, spacers and fittings requiring moderate strength up to 1300 °F (704 °C) and oxidation resistance up to 1500 °F(816 °C) but usage is not limited to such applications.
