    Stainless Steel Yeild Strength

    For Nitronic 40 and 50, the data sheets I found show a Rockwell hardness around 90. Will material be too hard/brittle to flex in our application?

    Stainless Steel Yeild Strength

    Thanks. Any suggestions for materials that could work? We looked into titanium however the cost is too high. Also the material will need to be able to be machined relatively easily.

    Stainless Steel Yeild Strength

    I am looking for a non magnetic Stainless steel with a yeild strength greater than 800Mpa and a modulus of elasticity of around 200,000. Cost is a factor so I am looking for the most cost effective option. Any suggestions?

    Gas impermeable plastics suitable for ultrasonic welding

    Thank you all for the help. We would like the shelf life of the part to be around 10 to 15 years, however we have yet to define an exceptable amount of nitrogen leak in our spec. The nitrogen within the part is primarily used as a dielectric and arc extinguisher. The main spec involved with the...

    Gas impermeable plastics suitable for ultrasonic welding

    The pressure of the sealed nitrogen will be 22 psi at room temp and the max operating temp of the part will be 150C. We are essentially attempting to change from using a metal can and epoxy too acheive a hermetic seal, to using a ultrasonically welded plastic container. That being said, the...

    Gas impermeable plastics suitable for ultrasonic welding

    Is it possible to mold mylar? My understanding was that it is used primarily in films. I would need a robust plastic that would be acting as a housing for other parts.

    Gas impermeable plastics suitable for ultrasonic welding

    Thank you. I will be sealing pressurized nitrogen in a molded plastic package. Would Mylar be conducive with ultrasonic welding?

    Gas impermeable plastics suitable for ultrasonic welding

    I am looking for suggestions of a plastic I can use as a gas impermeable package. The key is that this plastic needs to have a low permeablility, good strength, and also be suitable for ultrasonic welding. Any help or advice would be greatly appreciated
