Click on images below to view groups. If you are having problems assigning particular grades to a group as per ISO , there is help at hand. The two routes may be interdependent. Carbon steels that have been thermo-mechanically treated or quench and tempered are included in groups 2 and 3. There are three further technical reports which assign the material classification to the intended group.

The common structural steel now used in South Africa conforms to the specification EN Iso/tr 15608 which is classed as group 1 and sub-group 1. Now in its fourth edition, this technical report provides guidelines for a uniform system for grouping materials not only for welding purposes, but iso/tr 15608 also be used for heat treatment, forming and non-destructive 15068.

These groupings are important as materials in the same group have similar weldability and therefore react in a similar manner when welded.

Focus on Standards – ISO/TR : SAIW

In ISOgroup 1 contains steels with a isk/tr yield strength upto a maximum of MPa, there are 4 sub groups within this group. Creep resistant materials which are primarily alloyed with Chromium and Molybdenum are classified in group 5. Common alloys found in the market are grouped as follow: The American system similarly iso/tr 15608 materials into groups, however ASME IX in QW explicitly classifies grades of materials to groups and not on the chemical composition and mechanical properties iso/tr 15608 as is the case with ISO Nickel alloys are grouped in group 9.

As the new generation high temperature creep resistant alloy P91 X10CrMoVNb alloy contains vanadium, the material is classified 51608 group 6.

Click on images below to view groups. Whilst there are similarities between the groupings of ISO and QW, the systems do not equate to one another and need to be considered independently.

Alloy — Group 21; Alloy — Group High carbon steels are classified in group The materials are grouped according to their chemical and mechanical specifications. As ISO is based on the properties of the iso/tr 15608, all materials can be grouped according to the properties and weldability of the material. Should a material not be specified iso/tr 15608 a grouping in the American system, it may be regarded as unassigned and therefore requires independent procedure qualification despite the material technically fulfilling the requirements of a particular grouping.

QW has for a number of years now also included the ISO classification of materials.

Aluminium alloys are covered by groups 21 to The two routes may be interdependent. The standard covers grouping systems iso/tr 15608 the following standardized materials and alloys: There are three further technical reports which assign the material classification to the intended group.

Carbon steels that iso/tr 15608 been thermo-mechanically treated or quench and tempered are included in groups 2 and 3. If you are having problems assigning particular grades to a group as per ISOthere is help at hand.

The first three sub-groups are for different strength levels as per the detail in the table below with the fourth group iso/tr 15608 for steels with improved corrosion resistance such as the weathering steels produced under the CORTEN trademark.
