Zinc plated rivet versus AISI 201 HT or 301 1/2 Hard
Zinc plated rivet versus AISI 201 HT or 301 1/2 Hard
(OP)
Gentlemen,
I'm toying with the use of Alcoa Huck BOM rivets to connect stainless steel railcar sideframes.
The SS is either AISI 201 HT (original) or 301 1/2 Hard (new repair components).
All these fasteners will be hidden under non-structural moulding, but it's not guaranteed they'll stay dry.
Any thoughts?
Thanks in advance,
tg

That was quick!
Will this accelerated corrosion weaken the rivet over time, or is it only a surface phenomenon?
I can accept a corroded "looking" fastener, but not a weakened one.

I have serious tool access issues related to using 2 piece stainless steel rivets. The alternative here is then to use stainless steel hex head bolts. What is an acceptable method of preventing loosening (for the next 30 yrs) for these types of bolts?
Loc-tite?
SS nuts with nylon inserts?
Both?
The other possibility is the dreaded stainless steel Magna-Lok, but it's not as robust as I would like.
Thanks again...

Regarding vibration loosening of conventionally threaded fasteners, this kind of application would need first and foremost a high level of clamp load, with possibly one of the useful additional features such as thread adhesive. Nuts with a nylon prevailing torque feature will not provide much benefit here, nor will any of the conventional lock washers, serrated heads, etc. You might want to investigate the proprietary lockwasher from NORD-LOCK:

Weld. Spot welding of high strength cold worked SS is a common practice.
