A.Hardness values listed are applicable to S3. A.Requires quenching and tempering.
  B.9 CR steel is an air-hardenable steel, at times retaining austenite down to near atmospheric temperature. Good practice is to allow the steel to cool to 150° F or lower before subjecting the steel to a tempering treatment or post-weld heat treatment.
