Bar Stock???

[matrix02]

I need 10' of (3/4&quot/(3/8&quot square steel bars. I will cut it into 4 28" bars, which will support 75LBs of pressure each. I will drill a 1/2" axle hole at the tip of each bar. The load will be mounted via 4 1/4" holes for some steel bolts.

I have tried for a month to find bar stock. Nobody has metal this thick. I'm in NYC, but I will order from anywhere. I've tried Home Depot..local metal shops...machinists...welders. People look at me like I'm crazy. How much should this cost?

You haven’t looked the right places & I’m surprised some machinist didn’t sell you some off his raw materials rack. I can get bar stock up to 4x6” cross-section no problem.

McMaster-Carr is quick and convenient although pricey. They have a New Brunswick, NJ branch (sales: (732) 329-3200), so you should have quick delivery.

I would like to thank you all for your prompt responses!! Way to go!!

I'm being asked what type of stainless steel I need. I told them 303 cause I don't know what I need. Each 26" 3/4 by 3/8 bar should be able to support 160LBS. It will be used near water in New York city. I assume I can protect the metal with paint.

I'm building off-road skates. Two 26" bars will have 1/2" axles drilled into them for the two wheels that will be attached to the ends of the 2 bars. A skate boot will be mounted to the center of the 2 bars via 4 1/4" holes for 4, 4" bolts. This device may come into direct contact with salt water from the ocean on ocassion, but this can be avoided if nessasary.

Don't use 303 SS -- it has built-in corrrosion problem (sulfide for free-machining). Depending upon how the material was rolled, the sulfide phase may have acicular structure (elongated needles) which causes passivation and electropolishing problems.
