H-13 Tool Steel Belleville Washers

Belleville washers are unique, conical shaped washers recommended for use in problematic or critical bolting applications. Their conical shape affords a high spring rate over a short deflection to retain the proper bolting stress in a variety of conditions. The loss of a sound bolted connection can lead to fugitive emissions, cause equipment failure, or catastrophic events. Belleville washers can eliminate bolted joint failures due to a variety of causes:

High-temperature bolt yield
Differential thermal expansion
Packing or gasket relaxation or creep
Vibration
Thermal cycling
High cycle applications

H-13 Tool Steel is a versatile chromium molybdenum alloy that resists thermal fatigue cracking which occurs due to cyclic heating and cooling. H-13 Bellevilles are a common, economical washer commonly used in conjunction with ASTM A193 Grade B7 and B16 flange bolting.
