Product Description

APPLICATION:

Our high-quality Smooth Trademark Hot Rolled Steel Wire, ranging from 2500-5500mm in specification and 6-400mm in diameter, is engineered to excel in demanding structural applications. Ideal for heavily loaded, welded constructions such as cranes, bridges, buildings, tankers, water tanks, and floodgates, this steel ensures superior performance at both room and reduced temperatures.

TECHNOLOGICAL INFORMATION:

Our steel's exceptional properties are attained through meticulous control over the type and concentration of alloying elements, tailored to meet stringent requirements. The semi-finished products are toughened and delivered to your site, eliminating the need for heat treatment. To preserve the steel's mechanical integrity, stress-relief post-welding should be conducted under specified conditions.

SEMI-FINISHED PRODUCTS:

Crafted with precision, our semi-finished products undergo controlled toughening processes and are shipped ready for immediate use, bypassing any need for additional heat treatment. Post-welding stress relief should be managed carefully to maintain the optimal mechanical properties of our steel.
