Chemical composition and mechanical properties of S460ML low alloy high strength plates

Introduction of S460ML steel plate:
S460ML is a thermomechanically rolled and weldable fine-grained structural steel with a thickness of not more than 120mm. S460 is non-alloy structural steel, and the trademark of S460ML steel consists of the following parts: Symbol letter S: Structural steel with a thickness less than 16mm yield strength value: the smaller yield value, M stands for heat treatment, that is, the meaning of hot rolling , the impact of the rule when the temperature is not lower than -50 degrees is marked with a capital letter L.

S460ML is European standard low alloy high strength steel plate, executive standard: EN10025-4.

S460ML low alloy high strength plates chemical composition:
C ≤0.18, Si≤0.65, Mn ≤1.80, P≤0.03, S≤0.025.

Mechanical properties of S460ML low alloy high strength plates:
The impact energy at -20℃ is 27J. Yield strength 275-355 MPa, tensile strength 450-680 MPa.

The use of S460ML steel plate:
Manufacturing plant, general construction and various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining cars, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports, etc. Machinery and other structural parts.

The related steel grades under EN10025-4 standard are S275M S275ML S355M S355ML S420M S420ML S460M.
