Applicable elongation and impact requirements depend on grade, wall thickness and specimen orientation.
A defining characteristic of EN 10216-2 is the specification of mechanical properties for elevated-temperature pressure service.
The standard provides minimum 0.2% proof strength (Rp0.2) values at elevated temperatures for applicable steel grades.
Verification of elevated-temperature proof strength can be specified at the enquiry and order stage, with the required test temperature stated by the purchaser.
Creep-rupture strength values are also provided in the standard for engineering reference.
Final material selection should follow the applicable design code and actual design temperature, pressure and service conditions.
Heat-treatment condition depends on the steel grade.
Typical delivery conditions for commonly specified grades include:
P195GH / P235GH / P265GH: Normalized or normalized forming
16Mo3: Normalized or normalized forming
10CrMo5-5: Normalized and tempered
13CrMo4-5: Normalized and tempered
10CrMo9-10: Normalized and tempered
The required delivery condition shall be confirmed according to the exact grade and EN 10216-2 requirements.
EN 10216-2 defines two test categories:
TC1 — Test Category 1
TC2 — Test Category 2
For applicable non-alloy steel grades, TC1 or TC2 should be specified at the enquiry and order stage.
TC2 includes additional inspection and nondestructive testing requirements compared with TC1.
For alloy steel grades, the applicable inspection and testing requirements are determined according to EN 10216-2 and the purchase specification.
