Product Description

APPLICATION:

Our high-performance steel is meticulously engineered for use in heavily loaded, welded structural constructions. It is ideal for cranes, bridges, buildings, tankers, water tanks, and floodgates. This steel excels in both room and reduced temperature environments, ensuring robust durability and long-lasting strength.

TECHNOLOGICAL INFORMATION:

The expert steel manufacturer determines the specific type and concentration of alloying elements, tailored up to the stated values to ensure the desired properties. These semi-finished products are delivered in a toughened state and do not require any heat treatment at the buyer's location. For optimal performance, stress relieving post-welding should be conducted under conditions that do not diminish the steel's mechanical properties.

SEMI-FINISHED PRODUCTS:

Our semi-finished products are crafted by our skilled steel manufacturer, who selects the appropriate type and concentration of alloying elements to meet specified values, thereby guaranteeing the required properties. These products are supplied in a toughened condition and are free from the need for heat treatment at the buyer's premises. To maintain peak performance, stress relieving after welding should occur under controlled conditions to avoid any degradation of the steel's mechanical properties.
