Steel is the most common material for spring washers due to its ease of process and its high tensile strength. Chrome vandium alloy is a higher quality steel with a good through-hardening capability; it is used to make very thick spring washers.
How to Prevent Swimmerâs Itch. Thereâs no cure-all to eliminate swimmerâs itch. The negative symptoms are, ironically, a problem of our own immune systemâs making, and short of abstaining from swimming altogether, thereâs a risk of getting swimmerâs itch in a Northern Michigan lake.
Apologies if this is a stupid question! I've just started swimming as rehab for a back injury. I'm currently doing 3-4 sessions per week, each session 30-45 minutes. The pool I swim at is clean, but there's no overpowering chlorine smell. I shower immediately after each session, but even hours later and also after a second shower, I can still smell the chlorine on my skin!
