New high strength steel
Carpenter Tech announced a patented high strength steel that does not
contain Cobalt. In fact reading the data sheet, it is a low alloy steel with high strength and toughness. http://finance.yahoo.com/news/PremoM....html?x=0&.v=1 Dan |

Perhaps similar to X45NiCrMo4 for many applications.
Seems to need cryogenic treatment for best properties possibly the high Si at work? wrote in message ... Carpenter Tech announced a patented high strength steel that does not contain Cobalt.

Do they offer free evaluation samples? jsw |

The Carpenter web site says -100 F for an hour for max toughness. -100 is cold but is about what you get with dry ice. I think of cryogenic as colder than that. Dan |

Dan You are probably right about the modern definition of cryogenic. The temp they quote is presumably to allow for the use of dry ice. I am probably using the term the way I did because at work we use liquid nitrogen cooled baths for all our work from -40°C to -196°C. |
