St52 steel (St52-3) is an unalloyed structural steel grade complies with DIN 17100.
DIN 17100 Standard applies to steel sections steel bars, wire rod, flat products, strip, plate, wide flats, seamless and welded, square and rectangular hollow sections, forgings and semi-finished products in the general structural steels named which are delivered in the hot formed or normalized condition after production.
DIN 17100 Steel is used to build bridges, shipbuilding which requires high strength.
ST52-3 grade steel is a readily weldable low carbon manganese steel with good impact resistance (including in sub-zero temperatures). This material is commonly supplied in the untreated or normalised condition. Machinability of this material is similar to that of mild steel.
