What SS wire is this-Suitable for standing rigging?

[HappyMdRSailor]

Hey All...

Ran into some wire that may be REALLY cheap dollar wise, but assuredly quality control to be top notch as it was to be utilized inside a nuclear steam generator...

Obviously, 1x19 is the standard of choice, and I'm familiar with wire rope properties re: stiffness, bending, ... This stuff looks like 7x7, or 7x19?

Probably a 20% reduction in overall strength, but...
1. Based on the pics, guess as to what the lay/construction is ?
2.Do mechanicals, Norseman/Stalock work on this?
3. Any issues with strength of swaged ends?
4. Too flexible or elastic for weight-length in 1/2" ?

I would hit all of these points myself, but auction deadline is A-Comin' Kah-WiCK!!

(ps headed to Brion's forum to ask too)

Looks like 7x19 to me.

Norseman makes a 7x cone for their fittings, Sta-lok does too.

Don't know.

Has about 2-2.5x the elastic stretch of 1x19.

Has lots more surface area and crack/crevice locations for corrosion as compared with 1x19 (and even more when compared with synthetics)

Thanks D!

The construction is what I was leaning toward, 7x19...

I DID know about the increased elasticity, but didn't realize it was so much... reading a few quick things over @ Brion's confirmed this, and his strong opposition to rigging with such... Of course, oversizing is an option, but who the hell wants to add weight aloft!?!?!

I've only used mechanicals with 1x, good to know and see they have other lay options...

The surface area and crevice issues were completely obvious, but appreciated comments to be sure...

One of the optional routes for rebuilding a rig was to get her up, and replace components with long term service pieces as they were acquired at a reasonably financial rate!

Thanks again man!

Oversized and inexpensive sometimes wins

In galvanized this and 7x7 used to be pretty common as standing rigging, but the high loads on modern rigs and weight issues drove us to more exotic (read '$$') materials.

Since you aren't positive what the lay is, are you sure it's stainless and not some weird super-autensic or Monel alloy? Industrial sites can often have all sorts of strange demands and I would guess nuclear reactors more than most. The upside is its likely to be over spec, the problem is some of those alloys trade strength for corrosion resistance (necessary in high temp salt steam).

The construction isn't ideal, and the alloy may be questionable... I wouldn't mess with it.

Agreed... AND... This rig is going to demand some pretty severe loads... If I had a bendy huge Spruce tree planted on the keel, and cotton sheets... Right???

Greg,

I was worried about this too... Nuke tends to run into a lot of 400 Series for corrosion... or Monel... But at the sacrifice of yield strength and other properties...

Imma let this go for sure for a permanent install...

Thanks for the posts guys...
