EN10025-3 S275N carbon steel

[!--oldtitle--] Pageviews:

S275N low alloy steel plate is a carbon (non-alloy) steel formulated for primary forming into wrought products.

S275N low alloy steel plate has a fairly high base cost among wrought carbon or non-alloy steels. In addition, it has a fairly low thermal conductivity and a fairly high embodied energy.
