Improvement of inclusion cleanness in bearing steel and Catreated steel
Revue de Métallurgie, 2007Two complementary techniques are mainly used for the detection and characterisation of the inclusions populations present in the steel bars in a large range of sizes: from 1 μ m to 1 mm: the automatic scanning electron microscope associated with image analysis and the 80 MHz ultrasonic inspection.

Defouling and cleaning using nanobubbles on stainless steel
Biofouling, 2009The present work demonstrates that nanobubbles can be used as cleaning agents on stainless steel (SS) surfaces. Cleaning efficiency has been quantified. Using an Atomic Force Microscope (AFM), it was demonstrated that nanobubbles can be produced by electrochemical treatment on a SS surface either with or without adsorbed bovine serum albumin (BSA ...

Revue de Métallurgie, 2005
Clean steel encompasses a multitude of concepts that are based on fulfilling customer requests. Clean steel can be produced in many ways depending on the existing equipment and detailed customer demands. A common feature of all clean steel production is tight process control along with continuous monitoring. Quality assurance is essential

Cleaning of Rusty Steel for Painting
British Corrosion Journal, 1971AbstractIn tests on small mild steel panels, the major constituent of the salt contaminants in the rust formed in an industrial area was identified as ferrous sulphate, which confirms previous findings. It was not possible to remove all traces of ferrous sulphate from the surface of the rusty steel by abrasive blastcleaning.

Clean Steel to Resist Hydrogen Embrittlement
CORROSION 1990, 1990Abstract Hydrogen embrittlement is know to affect steels in most sour gas environments. The purpose of the paper is to present the effects of cleanliness of the metal on its resistance to hydrogen embrittlement. The paper outline the effects of sulfur, phosphorus, oxygen and carbon equivalent contents on the H2 embrittlement resistance ...

Modern Refractory Practice for Clean Steel
2020Ductility facilitates reforming but elastic modulus provides the strength of steel. It all depends on constituents and phases in steel. The previous discussion emphasizes steel production is a multi-step process that has to pass through the exhaustive environment and thus possibilities of inclusions despite targeted compositions.

Laser cleaning of steel for paint removal
Applied Physics A, 2010Paint removal is an important part of steel processing for marine and offshore engineering. For centuries, a blasting techniques have been widely used for this surface preparation purpose. But conventional blasting always has intrinsic problems, such as noise, explosion risk, contaminant particles, vibration, and dust.

On Physico‐Chemical and Technical Limits in Clean Steel Production
steel research international, 2010AbstractGreat progresses in steel cleanliness have been attained during the last decades. In the measures of oxygen the lowest levels are approaching 5 ppm in Otot i.e. close to the thermodynamic limit of Al deoxidation. As the thermodynamics of the reaction system is firmly anchored to the steel chemistry and thus to the properties of steel and the ...

Cleaning Stainless Steel with Alkaline Solutions
2009Cleaning stainless steel in alkaline solutions begins with consideration of the soil, the alloy, the nature, size and value of the part to be cleaned, the amount of work to be processed, economics, the types of cleaning equipment available, the degree of cleanliness required as dictated by subsequent use of the part, environmental prohibitions, and ...
