Compact Stranded 1x19 Wire (Dyform) Groove

[B-Baysailer]

That looks pretty bad one almost looks like it's in cut in half.when I got my wire it came in a box from loos wire I used hi mod fitting on it

[Wotname]

Those later close-up pictures really show how bad it is.

And the number of strands compromised is excessive. I count at least 6 of the 19 and probably much more if you were to follow the damage up and down the length of the wire.

So I am now firmly in the camp that says "it is unacceptable".

Significant... on strength and longevity.. IMO. Pretty much the same thing.

Worked in a rigging shop for years and would often get bad spools in shipments of 2-3 pallets. Scratches and sometimes magnetic wire was not that uncommon. WE would return it every time.

Not sure other shops would have such a solid relationship with their suppliers.

You mentioned rust... I’d check the rigging with a good magnet...

Also that last image is kinda gnarly. I’d ask the rigger to replace it. Or just change it yourself. Either way, you’ll sleep better.

That would worry the crap out of me. That looks like a significant loss of strength.

Would you mind letting us all know who the manufacturer was?

I totally agree with you. This is area and the other 3 like it are beyond what I would be willing to let go. The first picture I posted is what they are calling "normal". I have two wires with a mark on them. One has three areas with damage like this and the other just has a small indent like the first picture.

Just trying to gauge if both wires should be replaced under a warranty.

I wondered the same thing.

Agree. We had planned on going out sailing but canceled when we saw this damage.

I agree that the second picture represents a significant impact on strength. It is badly damaged. I was suggesting that the first picture I posted on the first page where it is just a minor indention might not be significant. Thoughts?

Good idea on the magnet. I hadn't thought about that yet. I do not see rust anywhere but the grooves so I am inclined to think it is just where other metal has hit the wire but I will check with the magnet to be sure.

I am happy to share the rigging company name however I would like to wait for them to have a chance to resolve the issue. I am not looking to create bad blood. This could easily be a simple mistake in QC (maybe someone was in a hurry).

Hopefully they step up to resolve it and quickly. Unfortunately, so far it feels like I am getting shuffled around.

What would be determined with the proposed "magnet check"? 300 series stainless steels start out non-magnetic but can become somewhat magnetic when cold worked, and wire forming falls into that category I believe. The specific alloy and the degree of cold working affect the degree that a magnet (of unknown strength) will be attracted.

So what do you think will be learned ??

Well, I am under the impression that 304 stainless normally responds to a magnet but 316 normally does not. I was thinking that if it responds to a magnet it is likely 304 stainless or something other than 316 which is what is is supposed to be.

Perhaps my impression of this is incorrect?

To lend a little more credence to Jim’s statement as I know that apparently some take magnets to the chandlery to try to determine “good” SS, unfortunately cold working which also has a tendency to make the steel stronger like forging for instance also can make it magnetic.
There are two ways that threads can be put into screws and bolts, one is to cut them like a die does, and that seriously weakens the components. However the better and more common way is to pass the screw or bolt through rollers that literally squeeze threads into the fastener, this actually serves to strengthen the component but as it’s cold working it may make the steel mildly magnetic.
So it’s very possible that testing by magnet may pass up the “good” stuff and have you buying weaker stuff, possibly.

Die forming wire and indeed the manufacture of wire are both cold working, so if you pass up magnetic stainless wire, I’d assume your passing up quite a bit of wire.

Great information. Thank you. I was not aware that cold working could potentially cause it to become magnetic. I will keep this in mind in the future.

Any thoughts on other ways to determine quality for this kind of wire?
