Towing chain ASTM Grade 70

steelhigh-strengthindustrial

Product description Grade 70 is a high-strength, heat-treated transport/tow/binder chain commonly used for load securement in agriculture, construction, industrial, trucking and forestry. Grade 70 is intended for transport and binding applications and is NOT approved for overhead lifting. All Grade 70 chain is 100% proof tested; certificates are available on request.

Introduction Grade 70 chain was specifically developed for the transportation industry. It typically provides approximately 20% higher working load limit (WLL) than High Test (Grade 43) chain. G70 chains are also known as Transport Chain, System 7, or Spectrum 7. Grade 70 Chain is NOT approved for overhead lifting.

Features

• High-strength, heat-treated transport/tow/binder chain
• Greater hardness and durability compared with Grade 43 (High Test)
• Common names: Grade 70, Transport Chain, System 7, Spectrum 7
• 100% proof tested (certificates available)
• Not intended or approved for overhead lifting
