416BQ (No. 5 BQ)

416BQ (No. 5 BQ) is a balanced version of standard 416 stainless steel capable of producing a minimum hardness of Rockwell C 40 when bright hardened. The high hardness capability is obtained through very close chemistry and structure control, but it remains as machinable as 416 despite this. It can be cut rapidly and cleanly with regular metal cutting tools and can be freely ground and polished.
