Where to by chainplates online?

[aajora]

i made my 10 1/4”x2” chainplates with 316L flatstock from ONLINEMETALS.COM

for the ten chainplates it costed me about 250$ in SS, 50$ in polishing and sanding discs, 100$ for the electropolish and many hours of my own time!!!
so 400$ vs the thousands i was being quoted.

good luck

Who online specializes in chainplates to order?

Flat polished 316SS chainplate.
1.5" x 14.5" by 1/4" but looking too upgrade to 3/8"
6 holes drilled in, and upper end rounded off.

Schaefer makes one, SCH84-91 that would work after I double check the bolt hole distances. Those are $250ish online each, I need 12.

Try “Send - Cut - Send. “. They can cut anything out of any material on a CAD machine. Get a quote

As Madehn said these are fairly easy to drill and polish. I was able to find 316 stock 2"x3/8" bar stock at a local metal recycling center Alco in central California. I drilled the holes with a drill press and cobalt bits. Rounded the corners with a sabre saw and polished starting with 80 grit and going finer to 2000 grit wet and dry paper. It took a bit of time but the results are like factory made and four of them took less than a half a day. At $4/pound it was a great savings.

Garhauer is great and if you're not going diy I recommend them highly. For something as simple as bar stock polished up with some holes drilled I would definitely encourage you to do it yourself.

Well done! A question: how did you determine that the stock was indeed 316? Differentiating between the 300 series once the mill markings are gone is not a trivial task.

... and there is 316 and 316L ... and there is a difference. And, not all 316 is created equal. The "316" designation only really tells you the approximate percentage of chromium, nickel, molybdenum, and iron. It says nothing about impurities or treatments.

Admittedly, I know very little about metallurgy.

Do you mean electro-polished, .?

My two cents...

These guys advertise that they make replacement chainplates for all types of boats.

They are located in Ontario, Canada, (if that is an issue...?)

Same experience for me but 20years ago.

I just had a local Stainless Shop waterjet and laser cut two of 1/2" thick X 3" wide X 28" long, 6 square 1/2" holes and one 1" hole, rounded end, 2 pieces of 316L for $385. I can polish them myself or I can get them electropolished for about $100 locally. I'm in Texas at the moment and used Great Western Metals. Very pleased with their work. https://greatwesternmetals.com/

Probably. Something to do with dipping in them in a vat and turning on the power.

I second the vote for Garhauer, they will make chainplates for a reasonable price and the ret of their gear is reasonably priced and rugged. Been using them for 15 years now and have never been disappointed.

Consider titanium chainplates from Allied Titanium located near Port Townsend in Sequim. Chris Greimes is terrific.

Some of the "scrap stainless" has actual marking on to identify the alloy. Not always though so the unmarked stuff is a gamble but most seems to either 304 or 316. Granted there are other less desirable alloys. So far i have only gotten good stuff.
