P265GH Steel Specs & Applications

This document provides information on material number 1.0425, a heat-resistant pressure vessel steel. It lists the steel's chemical composition, mechanical properties including tensile strength and impact energy, and yield strength at elevated temperatures. The steel has good weldability and cold/hot forming properties. It is used to manufacture boilers, pressure vessels and pipes transporting hot liquids. The steel is supplied as hot-rolled coils or slit strip in various thickness and width ranges in a normalised condition according to EN 10028-2 standards.

Heat-resistant pressure-vessel steels

Material no.

1.0425

according to

DIN EN 10028-2

Tensile strength class

Usage
These steel grades are characterised by a
good weldability. They are used above all
for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
The user of these steel grades must
make sure that his calculation, design and
processing methods are appropriate for
the material. The grades of this series offer
good cold and hot-forming properties.

1) Average values of 3 samples; one individual


value may fall short of the required minimum value
by not more than 30%. The sample width shall
equal the product thickness if the latter is between
6 and 10 mm. The tests are performed by using
samples similar to Charpy-V samples. The values
specified in the table above are to be reduced
proportionally to the sample width.
