Understanding Grade B8M Fasteners

Grade B8M fasteners are heat-treated stainless steel fasteners designed to provide enhanced corrosion resistance, especially in chloride and marine environments. The "M" in B8M indicates Molybdenum (Mo) addition, which improves resistance to pitting and crevice corrosion.

Chemical Composition of Grade B8M Fasteners

The chemical composition of ASTM A193 Grade B8M fasteners is as follows:

The presence of Molybdenum (Mo) significantly increases corrosion resistance compared to B8 fasteners (which are Type 304 stainless steel).

Mechanical Properties of Grade B8M Fasteners

These properties make Grade B8M fasteners highly durable and resistant to stress and corrosion in demanding environments.

Types of Grade B8M Fasteners

Grade B8M fasteners come in various types, including:

Bolts (Hex Bolts, Heavy Hex Bolts, Carriage Bolts, Anchor Bolts, and more.)

Nuts (Hex Nuts, Lock Nuts, Flange Nuts, etc.)

Washers (Flat Washers, Spring Washers, etc.)

Stud Bolts

Threaded Rods

These fasteners are available in different finishes, including plain, passivated, and coated options for enhanced performance.
