I need some ER409Cb

admin

I'm mig welding an exhaust on my car. The pipe is 409L.  I'm trying to find a small spool 2#, of .030" ER409Cb wire.  Where can I look to purchase some?  Seems most suppliers only do wholesale business.Brian
Reply:409 stainless is just about the cheapest stainless there is.  It's very similar to mild steel but has just enough nickel and chromium to make it stainless.  I would weld it with 309L filler, this is my filler of choice for joining stainless steel to mild steel or joining just about any unknown combination of stainless steel alloys.

Reply:Actually 309L will have better corrosion resistance, in general.409 is barely stainless steel, as 76GMC1500 already pointed out.  309 contains more chromium and nickel, the alloying ingredients responsible for corrosion resistance in stainless steel.I'm not aware of any filler metal manufacturers that sell stainless solid wire in 2lb spools.  You might check some of the smaller, specialty manufacturers, but you may wind up paying more per pound that way.

Reply:As said, 409 is about the 'lowest' cheapest grade of stainless there is.There -is- 409 filler wire made.  But it's not a 'typical' item, unless you are maybe near Motown or someplace with a lot of stainless exhaust fab going on and the LWS is stocking it for them.And stainless (common stuff like 308, maybe 309 and/or 316) GMAW wire -is- available in little 2 pound (4 inch diameter) spools.  I have some 308 on a 2 pound spool.    Yes, it is pretty expensive on a per pound basis, but if you don't need or use a lot of SS then it sure is less expensive than buying a 'big' spool of cheaper-per-pound SS filler wire!  example of stainless GMAW wire on small(er) spoolshttp://www.ramweldingsupply.com/prod....mcic?c=103&m=  The best laid schemes ...

Reply:well, that's cool.  I didn't know anybody sold SS wire on a 2 lb spool.  But I can't say I like retailers that force you to register before you can see pricing or purchase.  That just rubs my fur the wrong way...

Reply:Register?  Oh, the zip-code thing.  I just put a nearby zip in and got to the product page.  I too don't like having to register or login just to see a product or price and rarely will do so, but just a zipcode (they are probably using it to check shipping and/or geographic locales of customers or potential customers) isn't too bad.Ram Welding was just the first vendor/supplier I put into a browser window.  I'm sure you could find similar SS wires at lots of other suppliers too.Like CyberWeld here  http://store.cyberweld.com/migwire.htmlOr IOC here  http://www.weldingsuppliesfromioc.co...IRE/Categoriesor lots of others I'm sure.    The best laid schemes ...
