  1. 1. Alternatives to pickling : preparation of carbon and low alloyed steel wire rod

    Författare :Peter Gillström; Magnus Jarl; Sven-Erik Lundberg; Tarras Wanheim; Örebro universitet; []
    Nyckelord :Mechanical descaling; shot blasting; pickling; steel wire rod; wear; drawing; Mechanical engineering; Maskinteknik; Maskinteknik; Mechanical Engineering;

    Sammanfattning : A well established method for scale removal on hot rolled wire rod is pickling. To avoid pollution problems, the wire rod can be mechanically descaled. By this method, the removed scale can be recirculated to the blast furnace. In batch pickling considerable energy is necessary; e. LÄS MER

  4. 3. Process-microstructure-corrosion interrelations for stainless steel

    Författare :David Lindell; Rachel Pettersson; Rebecca L. Higginson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; processing; annealing; pickling; microstructure; corrosion; anisotropy; oxyfuel; Kemi; Chemistry;

    Sammanfattning : Stainless steels were first developed in the early 20th century and have since then emerged as a very diverse class of engineering materials. Along with steels having new combinations of properties, there is a continuous development of new technologies allowing the material to be produced in a faster and more energy effcient manner.

  5. 4. Use of local electrochemical techniques for corrosion studies of stainless steels

    Författare :Nuria Fuertes; Rachel Pettersson; Mari Sparr; Ulf Kivisäkk; Yolanda Hedberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; passive film; thermal oxides; work function; pickling; SKPFM; SVET; XPS; AES; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The excellent corrosion resistance of stainless steels arises from the presence of a passive film on its surface. Above 10.5wt% Cr a chromium oxide of 1-3 nm is formed on the surface of the metal that in case of damage will reform and hinder further dissolution of the metal. LÄS MER

  7. 5. Use of localised techniques to elucidate the influence of process variables on the corrosion of stainless steels

    Författare :Nuria Fuertes; Rachel Pettersson; Inger Odnevall; Stuart Lyon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; corrosion; passive film; thermal oxides; Volta potential; pickling; deformation; cold rolling; AM; SKPFM; SVET; Kemi; Chemistry;

    Sammanfattning : Several factors during steel manufacture and fabrication can alter the passivity and corrosion behaviour of stainless steels. These include alloying, deformation, welding and heat treatments. LÄS MER
