The energy benefit of stainless steel recycling
The energy used to produce austenitic stainless steel was quantified throughout its entire life cycle for three scenarios: (1) current global operations, (2) 100% recycling, and (3) use of only virgin materials. Data are representative of global average operations in the early 2000s. The primary energy requirements to produce 1 metric ton of austenitic stainless steel (with assumed metals conce...
متن کاملPhotocatalytic reactivity of the titanium oxide loaded on a stainless steel screen by a spraying method
To reduce a film-diffusional resistance in the very vicinity of the photocatalyst surface, titanium oxide particles containing a small amount of adsorbent particles (310 %) are immobilized on a stainless steel screen by a spraying method and its performance is investigated by decomposing 2,4-dinitrophenol in water. It is found that the activity of this photocatalyst screen is higher than that o...
متن کاملDermal exposure to chromium in the grinding of stainless and acid-proof steel.
OBJECTIVES The aim of the study was to measure the dermal exposure levels of chromium dust during grinding of stainless and acid-proof steel parts. METHODS The potential dermal exposure of the body was measured with a patch sampling method and the actual exposure of hands with a hand-wash method. Simultaneously, personal air samples were also collected. RESULTS The range of body and hand ex...
متن کاملDirect current plasma spraying of mechanofused alumina - steel particles
Stainless steel particles (60 μm in mean diameter) cladded with an alumina shell (2 μm thick and manufactured by mechanofusion) were sprayed with an Ar-H2 (53-7 slm) d.c. plasma jet (I = 500 A, P = 28 kW, th = 56 %). Two main types of particles were collected in flight, as close as 50 mm downstream of the nozzle exit: particles with a steel core with pieces of alumina unevenly distributed at t...
متن کاملSurface characterization of austenitic stainless steel 304L after different grinding operations
Background: The austenitic stainless steel 304L is widely used as a structural material for which the finished surface has significant effect on the service performance. A study of the grinding process with regard to the quality of the ground surfaces is therefore interesting from the point of view of both industrial application and scientific research. Method: This work investigates the influe...
