Do you know define what metal might be considered the “most environmental”? I say aluminum because it can be recycled others on my team say brass.
758How is solution annealing carried out? Define what type of furnace is required? Does one need to be heat in a salt bath?
737Define what is the melting point of e70 steel, 304,308,316 stainless steels? In addition, define what is the hottest part of the flame in a fire?
676Is there a possibility of inducing stress cracking in an insulated stainless road tanker vessel (20 tonne capacity) if the vessel is subject to rapid filling (10 tonne /hr) with liquid methane (-160 c) assuming the vessel is at ambient. If so, where could I obtain suggested cooling rates?
650Is there any way through hardening and anodizing some type of aluminum, it could be as hard as steel? I have hardened steel rollers that run up and down on a ramp along with spring pressure. Alternatively, if you are familiar with snowmobiles, the rollers run on the helix on the secondary clutch.
616When we do cardonitriding or casehardening operation for a plain carbon steel the case depth, hardness & microstructure are not alike why and define what are the basic thing, which makes such a difference.
684Define what is special about the properties of chromium molybdenum steels that make them ideal for pressure vessels?
686Does case harden steel properties detoriates over time? Especially for guns, parts like bolt carrier, the brand new parts has been kept for 10 year and properly oiled. I am worried about its surface hardness to take the blow during firing.
