Need information on welding ASTM A-108 1213-1215. It is screw machine stock and the only information found to date is that it is not considered weldable because of the high sulfur content.
Background information:
Thickest joint member is 3/8". Welding process that needs to be used is GMAW or...
Looking for a polymer to extrude over a metal coil. Material must be gamma sterilizable to 90 kGy, Coil is approximately 10 ft. long and 0.1 in. in diameter. Material must be low cost.
What kind of factor will a velocity of 300ft/sec have on the wear rate of 316 Stainless Steel? If (and why) 316 is not recommended, what castable alloy would be recommended?
Need mold material or coating to:
1. Survive reaction temperature of 4500F, which produces superheated liquid (Tm=1980F)
2. Act as permanent release agent
3. Withstand 50-1000+ cycles
Thanks.
What "grade" of boron is used in polyethylene sheets, i.e. Boron-6, Boron-10, etc.? Why is it at low levels (1-5%)? Can you explain the mechanism? For instance, when greater protection is required a thicker sheet of polyethylene is used. Why isn't more Boron added? Is it due to saturation? Is it...
