Abstract

1325899 Heat treating stainless steel STAHLWERKE SUDWESTFALEN A G 30 Oct 1970 51770/70 Heading C7A A martensitic steel containing in percentage by weight: is heat treated at a temperature such that the microstructure is 50-100% austenitic, and is then cooled at a rate such that the resultant structure is at least 50% martensitic. Strip may be treated continuously at 850-1100‹ C for 5 seconds to 12 minutes, while thicker section material may be treated for 8 to 60 minutes.
