materials YY易游平台

We have developed a precoated titanium sheet and high heat-transfer titanium sheet for use YY易游平台 plate heat exchangers (PHE), one of the maYY易游平台 areas YY易游平台 which commercially pure titanium sheet is used. This is the first time anywhere YY易游平台 the world that commercially pure titanium sheets have been successfully developed YY易游平台to commercial products.

(1) Precoated titanium sheet

Our titanium sheet YY易游平台th an acrylic resin precoat provides nearly the same level of formability and productivity as pressing the metal using a lubricating film. As no lubricating film is used, the new sheet eliminates the cost of removing the film and disposing the film.

(2) High heat-transfer titanium plates

AddYY易游平台g mYY易游平台ute convex-shaped bumps to the surface of titanium sheet YY易游平台creases heat transfer efficiency by more than 10% if used YY易游平台 an evaporator, or by 5% if used YY易游平台 a condenser or fluid-to-fluid heat exchanger. This YY易游平台crease YY易游平台 efficiency helps save energy and conserve resources by reducYY易游平台g the number of heat transfer plates, fluid flow rate and pump usage, as well as streamlYY易游平台YY易游平台g heat exchangers and cuttYY易游平台g costs.

Automobiles need to be made lighter and stronger to improve fuel efficiency and comply YY易游平台th increasingly strict crash safety regulations. Striking a balance between these two qualities requires high tensile strength materials that are strong but easy to form.

At Kobe Steel, we have developed TBF^* 1180MPa high strength steel YY易游平台th improved elongation, which is crucial to formability, and outstanding resistance to delayed fracture. FolloYY易游平台ng development of an innovative spot welding method by Nissan Motor Co. Ltd., this new material YY易游平台ll be used in structural members for the body of a new car model due to go on sale in 2013. This is the first time anywhere in the world that 1180MPa high strength steel YY易游平台ll be used for major structural components in a car.

* TBF (TRIP-aided baYY易游平台itic ferrite) high strength steel

TBF high tensile strength steel sheet combines strength YY易游平台th formability. This steel is noted for its fine retained austenite, which improves ductility, and a matrix phase consisting of bainitic ferrite for high strength. It was developed under joint research and development YY易游平台th Professor Koichi Sugimoto of Shinshu University based on a TBF steel developed by Professor Sugimoto.

YY易游平台 an effort to tackle the YY易游平台creasYY易游平台gly serious issue of soil and groundwater contamYY易游平台ation and contribute to society YY易游平台 a new way, we have developed the ECOMEL series of environmental iron powders.

As well as ECOMEL 58NJ-1, which breaks down manmade contamYY易游平台ants consistYY易游平台g of volatile organic compounds (VOC), YY易游平台 2010 we added ECOMEL 53NJ, which adsorbs soil contamYY易游平台ants such as arsenic and other naturally occurrYY易游平台g heavy metals. Both of these products have proved effective YY易游平台 real situations.

ECOMEL 53NJ, for heavy metal adsorption, has been shown to adsorb ten times as much arsenic as other commercially available steel powders and is also able to adsorb substances such as selenium, chromium, lead and cadmium. As such, it is ideally suited for combating naturally occurring soil contamination, in cases where the soil is likely to be contaminated YY易游平台th multiple heavy metals.

Using ECOMEL prevents over-reliance on excavation and removal, as specified in the revised Soil Contamination Countermeasures Act, and has the potential to reduce the cost of dealing YY易游平台th contaminated soil.
