DIN 7527 std & 1.0570 Grade material _ Round Bar

[Gregorydas]

Hello All,

I am stucked while estimating a crane girder, because there is two round bars to be machined. It's description in the drawing is as follows;

1. Round bar 190 x 1000 mm x 4 Pcs
Standard: Din 7527
Material: 1.0570

2. Round Bar 350 x 120 mm x 4 Pcs
Standard: [highlight #FCE94F](they have not given)[/highlight]
Material: 1.7225 + QT

Somebody please give the exact equivalent ASTM or EN grade for this. At least to recognise whether it is SS or CS.?

The most recent European standards specify S355J2 (1.0577) according to EN 10025-2. Many German producers still reference the older 1.0570 steel number. They are essentially identical. 42CrMo4 (1.7225) is specified in EN 10083-3.
