Reference blocks for Hydrogen Induced cracking

Hello,

1. Can someone suggest a method of getting a 200 mm thick carbon steel sample with hydrogen Induced crack ? I wish to use it for studies on Ultrasonic charecterisation. If some one in India can spare me a sample, I will return the same after my study.
2. Can I use a sample with IGSCC for the above purpose ? Are these two damages similar ultrasonically ? Can some one thrw some light ?

Re: Reference blocks for Hydrogen Induced cracking
If no one supplies you with a suitable sample NACE have procedures for exposure to atmospheres to induce cracking. Also CAPCIS in the UK have a Pipe Full Ring Test that can induce HIC in steels.

Labs such as CAPCIS at Manchester and CLI in Houston may well be able to help you.

...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
