Good to know 👍🏼.
I worked in the office furniture industry for 42 years. We started with coiled steel: 12 to 24 gauge. Shearing, stamping, punch-pressing, welding, etc.
Outside of that realm, there is a lot that I haven’t experienced. We were doing laser cutting the last 20 some years: neat stuff.

Thats a long time lol The laser cutting is a cool way to to make a lot of parts. I just wished my Father would of invested in a nice turret strippet punch it would of been a big up swing in our production of Aero space and casino parts.

 

[Blackfoot58]

Yes. We had about 40 turret presses amongst several locations. Mostly Amadas with auto-indexing. Some were auto load/ auto unload. Could run without an operator.

 

[Mine Shaft]

Omg 40 turrets you guys must of been spitting the parts out like there was no tomorrow lol.

 

[Blackfoot58]

In the 60s through early 80s it was all done with individual punch presses. Thousands of parts per day.

I have a bunch of ST/S dimpled sheets left over from my scrap metal yard days. I wanted to get them cut/formed into stainless cookie/baking pans because to buy one is crazy expensive.

Question: How can I tell if the stainless has been oiled or not?
It was a statement of beware from one fabricating company I have dealt with over the years getting railings and lintels.

Hi pepper j. I have never heard of Oiled SS but check your Stainless steel to see if it's Magnetic if not then its a Cres = Corrosion Resistant Steel. Most of all restaurants use a higher grade SS even some silverware, forks and spoons say Stainless Steel, but put a magnetic to them and I bet it will stick lol.

All the sheets are 304 Stainless I know that for a fact as they were tested with a XRF. 4'x8', and 5'x10' even the checkerplate is 304.
I bought skid lots of aluminum and stainless sheet.
Never had any 400 series stainless from this customer.

 

[Mine Shaft]

Yes that's good SS 304 but as far as oiled goes not sure what they are talking about lol all my 304/321 SS was clean if they are talking about a thin coat of oil that will clean right off.

 

[Mine Shaft]

That SS Diamond plate is some high priced stuff.

That's what I thought also if cleaned and washed it would be like any other SS304. I certainly would think it would be better than the SS 400 series most things are made of.
