EN10025-4 S460M steel

S460M steel sheets are widely used in the bridge construction , mining machinery, pressure vessels and so on. The S460M iron is hot rolled weldable fine grain structural steels.

The verification of the S460M impact energy value shall be carried out in accordance with EN10025-1.

Furthermore the verification of the impact energy value shall be carried out,unless otherwise agreed with longitudinal test pieces for:
-M at -20℃
-ML at -50℃

The S460M steel products can be suitable for hot-dip zinc-coating,EN ISO 1461 and EN ISO 14713 should be used to set these coating requirements.The definition of suitability classes based upon chemical analysis limitations as laid down in EN10025-4 table 1can be used for guidance purposed.

For the CLASS 1,the Si≤0.03，Si+2.5P≤0.09
