403CB+, H46, B50A365, S40300, B50A365B,403 Stainless Steels - Special Steels Applications and Specifications

403CB+, H46 grade stainless steel is an AOD + ESR melted alloy with additional alloying elements giving it good strength and temper resistance at higher temperatures up to 1200oF. Similar to the 410 stainless this grade has the ability to be heat treated to multiple different strength levels. Because of the temper resistance this alloy is soley used in the power generation market as steam and gas turbine blades.

General Electric Material B50A365 identifies a Chromium-Niobium alloy steel used for compressor blading, turbine blading, and forgings.
This specification contains the following classes:B50A365A, B50A365A1, B50A365B, B50A365, B1B50A365C, Electric furnace material, heat treated for final properties Electric furnace material, annealedConsumable - Electrode remelt material, heat treated for final propertiesConsumable - Electrode remelt material, annealed Forgings for Non-bucket applications - Consumable Electrode remelt material, heat treated for final properties.

Material shall be heated to a temperature of 2000-2050°F (1095-1135°C) and held at temperature for sufficient time to assure uniform temperature within the load and each part thereof. The material shall then be quenched in oil or rapidly moving air, as approved in the manufacturing process plan,to a temperature below the Mf martensite finish temperature, to assure complete transformation. Material made to Classes A and C and material that is made to Class B without straightening or cold finishing shall then be uniformly heated to a minimum tempering temperature of 1185°F (640°C), and held for the time necessary to achieve all of the required properties.
