I have an application where using cerro bend ultra low melting point alloy would solve a lot of problems. I need a fusible link that doubles as an electrical connection that will destruct when the temperature goes above about 90°C (~190°F). Does anyone have any suggestions about using cerro bend...
In my shop and perhaps also in the field, I need an easy way to distinguish chrome-moly and chrome-moly-nickel steels (like 4130, 4140, and 4340) from the various grades of plain carbon steel. The problem is that the superficial characteristics of those steel groups are identical. For example...
Hi, Mandy: This phenomenon goes with the territory as is mentioned in the answer to your other question about crazing in hard chrome plating. The pin holing is actually taken advantage of and is used for the lining of engine cylinder bores, the pin holes acting as microscopic oil reservoirs to...
In my copy of the 23rd Edition Machinery's Handbook it specifically mentions that the 4130 test samples used for generating the data for that alloy in the properties section were quenched in water. The 1/4 inch thick parts in question after quenching and stress relieved at 300 degrees F should...
