Anyone used SS type 410? What are your experiences with it?

The description says not to be used in corrosive environments?

Stainless steels in the 400 group are called Martensitic and are very prone to hydrogen embrittlement (http://en.wikipedia.org/wiki/Hydrogen_embrittlement). Any hardened metals with hardness greater than 30 HRC are prone to hydrogen brittleness. 410 stainless has a hardness of 38-45 HRC (http://www.alleghenyludlum.com/ludlum/pages/products/xq/asp/G.4/qx/ProductLine.html).
