Product Description

APPLICATION:

Our High Strength Smooth Alloy Steel Sheet is ideal for various high-stress, welded structural constructions. Perfectly suited for cranes, bridges, buildings, tankers, water tanks, and floodgates operating at room and reduced temperatures, this steel guarantees durability and reliability under demanding conditions.

TECHNOLOGICAL INFORMATION:

The alloy type and concentration are meticulously selected by our expert steel manufacturers to ensure optimal properties. Delivered as toughened semi-finished products, they require no heat treatment at the buyer's site. Post-welding stress relieving should be conducted in a manner that preserves the steel's mechanical properties, ensuring long-lasting performance and structural integrity.

SEMI-FINISHED PRODUCTS:

Our semi-finished products are carefully crafted with precise alloying element concentrations to meet stringent property requirements. Provided in a toughened state, they eliminate the need for heat treatment on your premises. Proper stress relief after welding is essential to maintain the superior mechanical characteristics of our steel.
