The Plain Dealer
Swagelok Co. is preparing to market what it calls a breakthrough metallurgical technology that could make high-carbon, high-performance stainless steel.
[…]it has formed a subsidiary to commercialize a stainless steel heat-treating process it has used since 2000.
The new company, which has not been named yet, will be located in Greater Cleveland, said a spokeswoman. Its top officers — including the engineer involved in developing the process — will be shifted from the parent company. The patented procedure yields a very hard stainless steel alloy with superior corrosion resistance — a combination that the industry has traditionally not been able to produce.
Here is a more technical description of it, for those who are interested.
