Application

St3ps carbon steel is used in flat and shaped steel products, thick plates, hot and cold rolled coil, arc-welded pipes and sections, forgings, stampings and other metal components. These are used in construction and machine-building for manufacturing metal structures and components for use in normal temperatures.

 

Welding

St3pc steel can be welded without limitation. The standard methods include manual-arc, automatic-arc, contact and electroslag welding. Preheating and subsequent heat treatment is recommended for gauges over 36 mm.
