Product Description

APPLICATION:

Ideal for use in heavily loaded and welded structural constructions, our steel is perfect for cranes, bridges, buildings, tankers, water tanks, and floodgates, performing excellently at both room and reduced temperatures.

TECHNOLOGICAL INFORMATION:

Our steel manufacturer meticulously determines the type and concentration of alloying elements (within specified limits) to achieve the required properties. These semi-finished products are delivered pre-toughened, eliminating the need for heat treatment at the buyer's facility. Post-welding stress relief should be conducted under controlled conditions to maintain the mechanical properties of the steel.

SEMI-FINISHED PRODUCTS:

The steel manufacturer precisely selects the type and concentration of alloying elements (up to the specified values) to ensure the desired properties. Delivered in a pre-toughened state, these semi-finished products require no additional heat treatment at the buyer's premises. Stress relief after welding should be performed under conditions that preserve the steel's mechanical properties.
