According to the Korean "Labor News" on the 12th, the Korean Institute of National Academy of Sciences study of ferrous metals have recently successfully developed does not use nickel, glue stick stainless steel manufacturing technology.
Reported that the researchers used a very inexpensive way to manganese, chromium as raw materials, successful development of austenitic stainless steel. This is only the cost of stainless steel, glue gun about 20% of the past, with excellent non-magnetic, high strength. Light weight and other characteristics, by using the units of praise.
Nickel is a scarce resource, and people are likely to produce allergic reactions. Development of nickel-free stainless steel manufacturing technology has long been a topic of science and technology research.
