TuffDOM tubing is suitable for fluid power and other mechanical applications. Performance requirements for DOM tubing are more demanding than ever. Today’s customers insist that the mechanical properties of their tubing be virtually customized. They demand greater flexibility in combining qualities such as yield and tensile strength, hardness and ductility. And they want their tubing to be tougher.
The TuffDOM line of cold-drawn, stress-relieved tubing that has good mechanical properties for fluid power and other demanding applications. In test after test, TuffDOM has proven itself particularly suited to high load-bearing applications and to jobs where an exceptional ability to withstand severe stress or cold temperature is important.
TuffDOM 520 is made to normal yield strength level (75 KSI min.) and has typical longitudinal Cv impact of 30 ft. lbs. at -20° C on 10mm x 10mm specimens. Tests confirm that its mechanical properties are similar to SAE 1026 in yield and tensile strength while exhibiting greater elongation when manufactured under similar conditions.
TuffDOM 620 is made to a higher yield strength level (90 KSI min.) and has typical longitudinal Cv impact of 10 ft. lbs. at -20° C on 10mm x 10mm specimens. It is designed to provide increased (approximately 20%) mechanical properties compared to TuffDOM 520 and SAE 1026. All tension tests were performed in accordance with ASTM A-370.
