ULTRA HIGH-TENSION STEEL [BODY STRUCTURE]

id098013745600


Characteristics of Ultra High-Tensile Steel Plates

•  Ultra high-tensile steel plates have enhanced tensile strength compared to previous high-tensile steel plates.
•  Because the strength is maintained even though the plates are thin-walled, the ultra high-tensile steel plates are used for the frames and the main frame parts which form the cabin, reducing the weight of the vehicle.
•  Enhanced shock absorption has improved the safety.

Range of Use and Cautions for Service

•  Because the ultra high-tensile steel is hard and it may be difficult to reform, when extracting the damaged part using a frame repair machine, perform the work verifying that other parts are not affected.
•  When drilling welded parts, use a well-ground drill bit.
•  After welding, inspect the weld strength. If adhesion is poor, perform CO2 arc welding (plug welding).
