the more chromium in the steel the better.18 percent chrome in the steel and you have surgical stainless. chromium aka chrome is what is added to iron to make stainless

Stainless steel can and does rust, but its rate of rusting is much less than that for low chromium alloys. Stainless steel must contain at least 12% chromium to be classified as truly stainless. Other metals are added to enhance more specific properties of the steel.Just a note for info, some of the best stainless steel will show signs of rust if it was in contact with mild steel before it was installed, at hammer marks, rust on the skin from when it was slid across a mild steel work bench and rust from being wire brushed with a normal steel wire brush.What makes stainless steel "stainless" is a chromium oxide passive layer. If this layer is damaged, be it as a result of the manufacturing process or some other means, the exposed metal is able to be attacked and your stainless steel will show signs of rust. The trick is to restore the passive layer as soon after manufacturing as possible, as well as limit the exposure of the material to iron contamination through the manufacturing cycle.Some years ago i worked for a company that built equipment for use on oil rigs. The main material used in construction was stainless steel. The most important thing to remember was that under no circumstance where tools used for works on stainless steel to be used for any other material. For example if a hacksaw blade had been used for cutting mild steel it was not allowed near the stainless steel. If it was used on stainless it was said to contaminate the material and cause a reaction in the stainless steel. even the slightest contact with ferrous metals could instigate rust. This applied to any tool, spanners, hammers any cutting tool even abrasive disks.As I understand it, there are at least two types of stainless steel -- ferritic and austentitic. Ferritic will rust in the right environment, especially if water is present.
bs, it can corode or pit won't rust.
Nice quote from Wiki, but read it all the way to the end.
not sure how reading to the end changes anything and when I checked the full blown wiki page it told me nothing different. If you say it can corrode what is the corrosion made up of then???
ubee...thanx for the assist and a pretty good one at that. I know of the point we have to change all our tooling when running stainless but we do not send the parts out for passivating
The other myth is that to check to see if the mat'l is stainless use a magnetic...false
I have know many a machinist who thought this way and you could not tell them differently, even if you showed them.

Agree. I'm the plant engineer in a food plant, all our food contact equipment is stainless. I do not allow any of my technicians and fabricators to cross-contaminate tools used for mild steel and those used for stainless. I have witnessed rust forming on areas where the stainless was cleaned/buffed with a tool that was used with mild steel.

LookinforSnow... may I ask who made the Chicken wagon? Look's like a great job; plenty of good eats for all!
We had a few members of the club that got together and made it. We started by looking at a portable grill that another person had in town and then got developed our concept and started building.
Toolmaker - we cooked the chicken and served it at the Lodi Fair. Demo derby's both Friday and Saturday night. Good times.
I cleaned the grates with a pressure washer and everything came off pretty well. Not ready to put it away for an extended period yet, so for now it is good enough.
