Abstract CRUCIBLE F347 is a non-hardenable austenitic chromium-nickel steel that is particularly adaptable for use at temperatures between 800 and 1650 F. It is non-magnetic in the annealed condition but is slightly magnetic in the cold-worked condition. Among its many applications are aircraft-engine exhaust manifolds, boiler shells and high-temperature handling equipment. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-436.

Abstract CRUCIBLE 321 is a non-hardenable austenitic chromium-nickel steel which is particularly adaptable for parts fabricated by welding without postweld annealing for use at temperatures between 800 and 1500 F. This grade is non-magnetic in the annealed condition but is slightly magnetic when cold worked. Among its many applications are aircraft-engine exhaust manifolds, furnace parts and expansion joints. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-426.

Exhaust Gas Emissions

Aircraft engine technology has gained major advances in the past 40–50 years, steadily bringing significant gains in the reduction of exhaust emissions at the source. However, with the projected increase in air traffic, the cumulative amount of aircraft emissions will still increase. This maintains the need for further progress in developing analytical methods to predict the amount and composition of exhaust gases from aircraft engines to better assess the alternatives for reducing emissions and better inform decision-makers, manufacturers and operators. The Research Project “Aero-Gasturbine Emission Reduction and Simulation Technology”, started at the Delft University of Technology in collaboration with the Dutch National Aerospace Laboratory (NLR) and the Netherlands Ministry of Traffic, is aimed to contribute to the efforts to solve the problem. With the limitations, complexity and costs of emission measurements at operational conditions, the ability to predict engine exhaust emissions by means of analytical tools becomes more urgent for minimizing aircraft engine exhaust gas emissions. This paper presents a philosophy and approach to develop such tools.
