Grade Summary: A Chromium grade of stainless steel with phosphorous and sulfur added to improve machinability. Most readily machinable of the stainless grades. It is magnetic in all conditions and capable of a wide range of mechanical properties by heat treating. This grade is available in precision-ground pump shafting.
Typical Applications: Pump shafts and parts in machinery used in or around fresh water, food acids, and neutral and basic salts.
Available products: Round Bar and Hexagonal Bar
Typical Chemical Analysis:
