Round bar rolled diameter 20 mm 1.0570 - S355 - 11 523

Applications:

• Building structures (beams, frames, bridges)

• Mechanical structures

• General steel products requiring strength and toughness

Mechanical properties:

• Tensile strength (Rm): approx. 470 – 630 MPa

• Yield strength (Re): approx. 355 MPa

• Elongation (A5): 20 – 25 %

• Hardness: approx. 150 – 200 HB

Typical chemical composition (%):

• C: <= 0.20

• Si: 0.15 – 0.50

• Mn: <= 1.20

• P: <= 0.035

• S: <= 0.035

• Cu: <= 0.55

• Ni, Cr, Mo: trace amounts (depending on specification)

Processing:

• Forming: hot-rolled, can also be bent and welded

• Heat treatment: normally without special annealing; quenching/tempering possible for higher requirements
