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.
