Laser conducting-limited welding of thin-wall HR-2 hydrogen-resistant stainless steel (HRSS) parts is discussed,processing parameters is studied,fluctuation of penetration and its influencing factors are analyzed,and measures to control fluctuation of penetration are presented.

This paper reports the TEM study of the hydrogen resistant stainless steel HR 1, HR 2 and HR 3 which were charged with tritium in mixed atomsphere of deutium and tritium at elevated temperature.

The craftwork performance and resistance to corrosion of the Cu-containing antibacterial stainless steels;

In addition, the history and current status, characteristics, antibacterial principle and applications of antibacterial stainless steels are reviewed.

The antibacterial properties and relevant mechanism of copper-containing ferritic and austenitic antibacterial stainless steels have been studied.

Through experiments of the antibacterial property,protein leaking,adding cysteine as well as the bio-transmission electron microscopic technique,the antibacterial mechanism was primarily studied on the Cu-bearing ferritic antibacterial stainless steel against E.

With the improvement of people’s living and health level, antibacterial stainless steel has attracted much attention due to its structural and functional properties.
