XLERPLATE® steel boiler and pressure vessel grades are a range of specially designed plate products using a fully killed, fine grained carbon-manganese steel. These products are produced in a number of supply conditions, including hot-rolling and normalising.
Designed to provide guaranteed design strengths, guaranteed low-temperature properties and excellent weldability and formability, as these are critical for these applications.
Guaranteed minimum strength and design strengths are available as per AS 1210-2010 (R2021) across four different supply conditions. In addition, grades with elevated temperature properties or guaranteed low-temperature properties are also available.
Some XLERPLATE® steel's boiler and pressure vessels are recognised in the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel codes.

* The grades are available in the following supply conditions – NR (Normalised Rolled), N (Normalised), T (Thermo-mechanically Rolled) and NRA (Normalised Rolled, but tested in the Normalised condition). An explanation of the grade names and supply conditions is available on the Understanding Australian Boiler and Pressure Vessel Grades and Terminology article.
** Not all Low Temperature Impact tested grades are available in all thicknesses. Boiler and Pressure Vessel grades with Through Thickness Tensile requirements (Z grades) are also available on enquiry.
