High Strength Steels
Kromite® Threaded Bar
Heat Treated, Roll Threaded Rod
Kromite Threaded Bar is made of heat treated, high strength, alloy material. It is the ideal threaded rod to be used when strength and toughness are key requirements.
Kromite Threaded Bars are manufactured with a rolled thread vs. a cut thread. This product is virtually free of tears, chatter marks and tool marks that are commonly associated with cut threads. Such imperfections in cut threads are points of stress that cause fatigue failure in service. Consider Kromite Bar for your maintenance needs.
Material conforms to specifications for: ASTM A193, Grade B7. Call or email us for a quote.

Grain structure is maintained in continuous unbroken lines, increasing tensile and shear strength. As opposed to a commercial “cut” threaded bar where sharp cuts and gouges weaken the threads and can serve as stress risers.

The strength of our threaded bar is in the rolling process. Thread rolling deforms the blank material as it is forced along the contour of the die. The worked material is strain hardened, resulting in a product stronger and harder with minimal risk of fatigue relative to cut threads.
