Hydrogen Embrittlement Sustained Load Test Frame for Fasteners

Sustained load rig that holds fasteners at a set percentage of tensile strength for 200 hours to check for delayed fracture after plating. Used by plating houses and high-strength bolt suppliers.

Specification

Fasteners are tensioned through a lever or spring column and left for 200 hours at constant load, while a failure detector records any fracture. The test confirms whether electroplating and baking have prevented hydrogen embrittlement.

Features

• Eight-position lever loading frame
• Spring-loaded stations with automatic timer
• Failure detect switch and alarm per station
• Load tuned with digital load cell for calibration
• Sturdy steel base with rubber feet
