Product Description

APPLICATION:

Our Smooth Trademark Alloy Steel Coil is meticulously crafted for high-stress, welded structural constructions. Ideal for cranes, bridges, buildings, tankers, water tanks, and floodgates, it performs excellently at both room and reduced temperatures.

TECHNOLOGICAL INFORMATION:

The steel manufacturer meticulously selects the type and concentration of alloying elements to achieve the desired properties. Delivered as toughened semi-finished products, they require no further heat treatment on the buyer's premises. Post-weld stress relieving should be conducted under specific conditions to maintain the steel's mechanical integrity.

SEMI-FINISHED PRODUCTS:

Our semi-finished products are crafted with precision. The manufacturer carefully selects the alloying elements to ensure superior properties. Delivered in a toughened state, they do not require additional heat treatment by the buyer. Stress relieving post-welding must be performed under conditions that preserve the mechanical properties of the steel.
