Grade B8M Fasteners: Properties, Applications & Manufacturer Details

Introduction

Grade B8M fasteners are widely used in industries requiring high corrosion resistance and superior mechanical properties. These fasteners are manufactured from AISI 316 stainless steel, offering enhanced strength, durability, and resistance to extreme environments, including marine and chemical industries.

This blog will cover everything you need to know about Grade B8M fasteners, including their characteristics, applications, manufacturing process, and more.

What are Grade B8M Fasteners?

Grade B8M fasteners belong to the ASTM A193/A194 specification and are made from Type 316 stainless steel. These fasteners undergo carbide solution treatment and strain hardening, making them ideal for use in high-temperature and highly corrosive environments.

Chemical Composition of Grade B8M Fasteners

The chemical composition of Grade B8M fasteners includes:

The addition of Molybdenum (Mo) enhances corrosion resistance, especially in chloride-rich environments.

Mechanical Properties of Grade B8M Fasteners

These properties make B8M fasteners ideal for high-stress applications.

Types of Grade B8M Fasteners

Grade B8M fasteners are available in various types, including:

• B8M Hex Bolts
• B8M Stud Bolts
• B8M Nuts
• B8M Washers
• B8M Threaded Rods
• B8M Screws

Each type serves specific industrial applications, ensuring a secure and corrosion-resistant fastening solution.
