I've been less than thrilled with equipment from Spectro, there equipment doesn't seem to be as robust as some of their competitors. After warranty support is also not as good as some of their competitors. For OES, my order of purchase would be OBLF, represented in the US by Panalytical, who...
Ed, Thanks for the reply. I'm relatively new to Nadcap and this organization, though experienced in the industry. We currently demonstrate compliance to ASTM and AMS specifications mostly by certification changes and calibrations. We also run both internal round robins for employees trained for...
We're in the process of acquiring Nadcap certification for our internal laboratory and are having difficulty in finding an outside source for proficieny testing for general metallography and grain size. PRI's list of recognized providers does not have anyone currently providing that service for...
Does anyone have any experience using these either positive or negative? Our EAF production group is investigating the purchase of one to prepare samples from incoming scrap, and knowing what has happened in the past they specify it and then QC has the task of making it work
Looking at the worldwide guide to equivalent irons and steels, I do not see a 1528 grade. I see a 1527, and then a 1533. Grade series 1500 is filed under Carbon Steel, High Manganese. AISI 1527 for bar specifies C = .22/.29, Mn = 1.20/1.50, P = .040 max and S = .050 max. AISI 1533 for bar...
If McMaster is listing the hardness of the O1 you're purchasing as Rockwell B 89 to 110, you're purchasing annealed, not hardened O1. As long as you stay below 1330 F during your brazing operation the worst that should happen is a little decarburization and a possibly a little softening of the...
Meteng - thank you for the reply, it basically agrees with my gut feeling/knowledge. I know we haven't done either step, having discovered the tanks being welded on this past Friday and being the metallurgist in the group with the most experience in wrought materials. Most of our final products...
We have two tanks which are used as part of a VOD system coupled with mechanical vacuum pumps. The tanks are both probably converted pressure vessels (I know for certain that one of the 2 tanks is – based on the name plate, it was designed for a working pressure of 100 psig.) The name plate on...
Thanks for the reply - we actually have a wide range of spectrometers here 3 different OES spectrometers: an older ARL 3460 that is a work horse, a newer ARL Quantris, and a middle aged Spectro - works well, but we've used an after market service firm for it ever since I've been involved in...
We're looking at purchasing a Spectro iQ Gas Purge XRF for slag analysis. We're mostly making low alloy carbon steels for production of iron powders. Heat analysis usually had Mn around 0.10 %, carbon around 0.40%, Ni, Cr, Cu total of 0.10% or less. Everything else at residual element levels...
Ricky, I've looked at the worldwide guide to equivalent irons and steels. With a DIN designation, it should be of German origin, and the 18CrNi8 would lead me to believe that it's a variant of 304 stainless. I find 4 specifications in the guide - DIN 17440(96) with a designation of WNr 1.4301...
