Peter and I had a productive conversation this morning. We cleared the air on our disagreement. Peter is making a commitment to improve how they do things at NJSB, and are in the process of implementing those changes.
We discussed the W2 issue, and after having the steel that was tested at the brake foundry tested at their lab, Peter said the carbon was a bit low. I didn’t get the exact number, but he was honest that there was an issue. We discussed that the steel didn’t have any obvious carbide segregation, so the hypothesis is that some of the steel that is normally discarded from the edges of the roll made it past quality control. The majority of the steel was fine, which is why the certs they had showed normal composition. Peter said the steel was from 2018, and the current stock is from a different melt. If anyone has problems, contact Peter and he will sort it out.
What will be different:
Peter made a commitment to consult more with smiths and metallurgists, and is in the process of developing those relationships.
Certifications will be posted, and stock will be carefully tracked to streamline diagnosing issues in the future.
There will be a new website shortly, and the lost email problem should disappear.
Communication with NJSB will be easier, and they want suggestions from smiths.
Peter is doing hands on heat treating to increase his knowledge in the area.
They are going to send charpy samples to Larrin for every steel they carry.
They are sponsoring CATRA testing for their steels.
They will post detailed heat treat recommendations, as well as troubleshooting procedures, such as how to test your oven.
They will change the annealing procedure, so all steels should be less than 90% spheroidized. This will take effect for future melts, probably 18 months in the future.
Overall it was a positive conversation. The direction looks positive.
