S420ML thermomechanically rolled structural steel plate for low temperature service

Description

420ML structural steel is a thermomechanically rolled structural steel plate that provides high strength at low temperatures. 420ML structural steel meets or exceeds the requirements of S420ML in EN 10025-4.

Dimension Range

420ML structural steel is available in thicknesses of 7.00-63.00 and in widths up to 3300mm depending on the thickness. More detailed dimensions are provided in the dimension program.

Mechanical Properties

The tensile test is made transversally to the rolling direction in compliance with EN 10025-4.

Impact Properties

The impact test is made longitudinally to the rolling direction in compliance with EN 10025-4.
