Introduction to S460M steel plate
S460M plate is a European standard low-alloy steel plate, thermomechanically rolled and weldable fine-grained structural steel. S460M steel can be used for load-bearing parts of bridges, sluices, storage tanks, water supply tanks, etc. and low-temperature welded structures.
s460m steel plate technical standard: EN10025.
S460M steel plate heat treatment (delivery status): hot rolled.
