    摘要： The present invention relates to high-nitrogen duplex stainless steels with an excellent eco-index and pitting corrosion resistance, in particular, to providing duplex stainless steels with ferrite-austenite phases, comprising:16.5-19.5 wt.% of chromium (Cr), 2.3-3.5 wt.% of molybdenum (Mo), 1.0-5.5 wt.% of tungsten (W), 5.5-7.0 wt.% of manganese (Mn), 0.35-0.45 wt.% of nitrogen (N), with a remainder of iron (Fe). The high nitrogen duplex stainless steels with excellent eco-index and pitting corrosion resistance according to the present invention use manganese (Mn) and nitrogen (N) to exclude or mostly substitute Ni, which increases price instability of the steel grades and environment burden, to result in enhancing economic efficiency, price stability and eco-friendliness.

    摘要： The present invention provides an apparatus for manufacturing a truss structure using multi-point pins, a method of manufacturing a truss structure using the apparatus, a truss core sandwich panel having the truss structure, and a method of manufacturing the truss core sandwich panel. The apparatus includes a metal plate, clamps, an upper die and a lower die. The clamps hold the metal plate. The upper die has upper multi-point pins which press the metal plate downwards. The lower die has lower multi-point pins which press the metal plate upwards. The metal plate has first and second points that respectively correspond to the upper and lower multi-point pins. The first points are extended downwards by the upper multi-point pins, and the second points are extended upwards by the lower multi-point pins. Thereby, many symmetrical sides are formed in the truss structure, thus increasing the stability of the truss structure.
