Detail Information
Introduction
Grade 431 stainless steels are martensitic, heat-treatable grades with excellent corrosion resistance, torque strength, high toughness and tensile properties. All these properties make them ideal for bolt and shaft applications. These steels, however, cannot be cold-worked owing to their high yield strength, hence they are suitable for operations such as spinning, deep drawing, bending or cold heading.
Application
Typical applications of grade 431 stainless steels include the following:
Laboratory equipment
Marine systems
Beater bars
Pump and propeller shafts
Nuts and bolts
