Abstract J and L Type 409NI is a ferritic stainless steel with 11% Cr. It exhibits an excellent combination of good formability, economy, and resistance to oxidation and corrosion. It is typically used in automotive exhaust systems or where more forming is required. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming and joining. Filing Code: SS-902. Producer or source: J & L Specialty Steel Inc.

Abstract Armco 11 Cr-Cb stainless steel has higher silicon content and is dual stabilized with titanium and columbium (niobium). The alloy is designed for use in automotive exhaust systems and should be considered where the performance of AISI Type 409 stainless steel is marginal. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep and fatigue. It also includes information on corrosion resistance as well as joining. Filing Code: SS-690. Producer or source: Armco Inc., Specialty Steels Division.

Carbon Filaments

Considerable effort has been directed toward an improved understanding of the production of the strong and stiff ∼ 1-20 μm diameter pyrolytic carbon fibers of the type reported by Koyama and, more recently, by Tibbetts. These macroscopic fibers are produced when pyrolytic carbon filaments (∼ 0.1 μm or less in diameter) are thickened by deposition of carbon during thermal decomposition of hydrocarbon gases. Each such precursor filament normally lengthens in association with an attached catalyst particle. The subject of filamentous carbon formation and much of the work on characterization of the catalyst particles have been reviewed thoroughly by Baker and Harris. However, identification of the catalyst particles remains a problem of continuing interest. The purpose of this work was to characterize the microstructure of the pyrolytic carbon filaments and the catalyst particles formed inside stainless steel and plain carbon steel tubes. For the present study, natural gas (∼; 97 % methane) was passed through type 304 stainless steel and SAE 1020 plain carbon steel tubes at 1240°K.
