Properties

Properties


Mechanical properties

Metallic coated structural steel?grades have the following mechanical properties (skin-passed) - these are measured longitudinal to?the rolling direction:

EN 10346: 2015 Grade S280GD+Z/+ZM
Min. yield strength Rp0.2 N/mm2 280
Min. tensile strength Rm N/mm2 360
Elongation % 18
If the yield point is pronounced, the values apply to the upper yield point ReH.
For all grades except S550GD+Z a range of 140 N/mm2 can be expected for tensile strength.
Elongation after fracture uses test piece length L0 = 80 mm.
For a thickness t ≤ 0.7 mm the minimum elongation after fracture is decreased by 2% and for a?thickness t ≤ 0.5mm the minimum elongation after fracture is decreased by 4%.

Properties


Mechanical properties

Metallic coated structural steel?grades have the following mechanical properties (skin-passed) - these are measured longitudinal to?the rolling direction:

EN 10346: 2015 Grade S320GD+Z/+ZM
Min. yield strength Rp0.2 N/mm2 320
Min. tensile strength Rm N/mm2 390
Elongation % 17
If the yield point is pronounced, the values apply to the upper yield point ReH.
A?range of 140 N/mm2 can be expected for tensile strength.
Elongation after fracture uses test piece length L0 = 80 mm.
For a thickness t ≤ 0.7 mm the minimum elongation after fracture is decreased by 2% and for a?thickness t ≤ 0.5mm the minimum elongation after fracture is decreased by 4%.

Properties

Properties


Mechanical properties

Metallic coated structural steel?grades have the following mechanical properties (skin-passed) - these are measured longitudinal to?the rolling direction:

EN 10346: 2015 Grade S350GD+Z/+ZM
Min. yield strength Rp0.2 N/mm2 350
Min. tensile strength Rm N/mm2 420
Elongation % 16
If the yield point is pronounced, the values apply to the upper yield point ReH.
A?range of 140 N/mm2 can be expected for tensile strength.
Elongation after fracture uses test piece length L0 = 80 mm.
For a thickness t ≤ 0.7 mm the minimum elongation after fracture is decreased by 2% and for a?thickness t ≤ 0.5mm the minimum elongation after fracture is decreased by 4%.

Properties


Mechanical properties

Metallic coated structural steel?grades have the following mechanical properties (skin-passed) - these are measured longitudinal to?the rolling direction:

EN 10346: 2015 Grade S450GD+Z
Min. yield strength Rp0.2 N/mm2 450
Min. tensile strength Rm N/mm2 510
Elongation % 14
If the yield point is pronounced, the values apply to the upper yield point ReH.
A?range of 140 N/mm2 can be expected for tensile strength.
Elongation after fracture uses test piece length L0 = 80 mm.
For a thickness t ≤ 0.7 mm the minimum elongation after fracture is decreased by 2% and for a?thickness t ≤ 0.5mm the minimum elongation after fracture is decreased by 4%.
