What is ISO 16573-2 - Slow rate strain test about?
ISO 16573-2 is the second part of the ISO 16573 multi-series on measurement methods for the evaluation of hydrogen embrittlement resistance of high-strength steels.
ISO 16573-2 provides an evaluation method of the resistance of high-strength steels to hydrogen embrittlement (i.e., hydrogen delayed fracture) using a slow strain rate test with hydrogen pre-charged specimens.
ISO 16573-2 includes testing methods for either smooth or notched specimens.
ISO 16573-2 is applicable to ferritic base steels.
Who is ISO 16573-2 - Slow rate strain test for?
ISO 16573-2 on measurement method for the evaluation of hydrogen embrittlement resistance of high-strength steels is useful for:
- Steel foundries
- Suppliers or dealers of steel products
- Metallurgists
- Civil engineers
- Architects
- Quality control personnel
Why should you use ISO 16573-2 - Slow rate strain test?
The mechanical properties of high-strength steels, such as tensile strength, elongation and reduction of the area would be degraded by the effect of hydrogen, known as hydrogen embrittlement, and the susceptibility of hydrogen embrittlement becomes greater by increasing the strength level of steels.
ISO 16573-2 provides you with detailed guidance on the slow strain rate test method to help you perform it accurately. ISO 16573-2 helps you recreate the environmental conditions that steel products or steel structures might undergo in the field.
Overall, the slow strain rate test method described in ISO 16573-2 helps you to identify the hydrogen embrittlement resistance of your steel products and structures in a specific environment. This helps you to identify the most suitable strength class steels for a specific environment and application.
