They are quite well made. I've used them half a dozen times with no problems. I don't wash them in the dishwasher, mainly because dishwasher detergent is very harsh compared to hand washing, and I think that will make them rush to where it's welded. The metal appears to be stainless steel (not sure what brand) but it's annealed which is quite soft so it's pretty easy to bend. Don't expect them to be heavy.
