Briefing

431 Stainless is a high-carbon steel with a minimum chromium content of 12%. It offers high hardness and excellent corrosion

Detailed

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
