Abstract SAE 10053 is an oil or water-hardening machinery and tool steel for applications where a shallow-hardening steel of high strength with moderate toughness meets the requirements. It is commonly used for parts where induction hardening or austempering are employed. SAE 1053 is recommended for agricultural machinery and tools, hand tools, shafts, springs and heavy-machinery parts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: CS-70. Producer or source: Carbon steel mills.

Mechanical Properties And Corrosion

The shaft parts surface was treated by ultrasonic surface machining (USM) technology after surface induction hardening and tempering. In order to study the surface strengthening mechanism of ultrasonic punching on the surface of induction quenching and tempering, nano-intendation, X-ray diffraction, and scanning electron microscopy equipped with energy dispersive spectroscopy were utilized to evaluate the mechanical and corrosion properties of untreated and USM-treated surface. The results indicated that the surface treated by USM had an obviously gradient plastic deformation layer and the grain of lath martensite was refined by this deformation. The surface mircohardness of USM-treated sample had a gradient trend, and the surface highest hardness was increased. Surface residual stress of USM-treated specimen was higher than untreated surface. The surface of USM-treated specimen also exhibited a lower friction coefficient, and a smaller wear scar. In addition, the surface of USM-treated sample had better corrosion resistance than untreated surface.

Although the anodising process has been widely used in surface treatment of Al alloys, the well known sulphuric acid anodising process produces inhomogeneous and highly porous anodised coatings on Al alloys containing high Si due to the inertness of the silicon particles. The present work reports a novel micro-arc anodising process for such high-silicon aluminium alloys. Uniform and thick anodising coatings can be obtained through an anodising process in an alkaline electrolyte under high voltage and low current density conditions. The microstructure examination in SEM indicates that most pores in the coatings have been sealed during the anodising process, thus post-treatment that is normally needed for the currently used anodising process can be eliminated. The coating is very promising in the improvement of corrosion resistance for cast high-silicon aluminium alloys.

Small amounts of nickel are added to titanium to improve the crevice corrosion resistance but this results in an alloy which has sheet fabrication difficulties and is subject to the formation of large Ti2Ni precipitates. These large precipitates can serve as local corrosion sites; but in a smaller more widely dispersed form, they can have a beneficial effect on crevice corrosion resistance. The purpose of the present work is to show that the addition of a small amount of Mo to the Ti-1.5Ni alloy reduces the Ti2Ni precipitate size and produces a more elongated grained microstructure. It has recently been reported that small additions of Mo to Ti-0.8 to lw/o Ni alloys produce good crevice corrosion resistance and improved fabrication properties.
