Stainless steel Definition and 80 Threads

Please redirect me to the appropriate forum if I have posted in the wrong place... This stuff is FAR over my head, and I need somebody with some real knowledge of thermodynamics and heat flow... I own a scuba dive shop and of course we compress air to very high pressure, on the order of 300...

I am working on a prototype for a laser component. We have a stainless steel box, that is flooded with water for cooling. There is current and UV light in the box, so to isolate the current from seeing the steel I am lining the walls, about 1.5 mm thick, with a resin. I'm looking for...

Hello All, I'm hoping someone can assist me in locating a stress amplitude vs. cycles curve (S N curve) for a Duplex Stainless Steel. The particular material I'm using is SAF 2205. I have been searching far and wide, including the Atlas of Fatigue Curves, but I have not been able to find...

Is Passivation to s/s = to Zinc Clear Coating of s/s? I know passivation is adding a layer of chorosion inhibtor the the surface so can this layer be clear zinc or are these different means of coating s/s?

I have two probes. They consist of a stainless steel cylinder inside another, one held by epoxy and one held by acrylic. I can measure a voltage difference between them. I have placed them in tap water and applied a 5V difference across them then disconnected the voltage. The problem is that...

Hi I need a way of joining a very thin strip of stainless steel mesh to form a cylinder. It forms the 300 micron mesh cylinder that sits inside a inline "Y" type strainer. The one i have currently doesn't seem to be joined by adhesive but by a heat crimp or sum sort of non...

What is the best way to distinguish and separate chrome steel, carbon steel, and stainless steel? I.e., if I had balls of chrome steel, carbon steel and stainless steel that were all of the same size, how could I tell them apart? The weights of the materials are very similar, and I am looking...

Properties of Matter (Fluids) Why is it possible to float a wax-coated stainless steel needle on the surface of water?

Hello, I am looking for static and dynamic coefficients of friction for bronze on stainless steel (dry condition). Closest thing I could find was http://www.engineershandbook.com/Tables/frictioncoefficients.htm" where it only has steel on bronze under greasy condition. Can anyone help me...

Hello, I'm looking to experiment with an Electrothermal-Chemical (ETC) system of accelerating a projectile. Basically, it will involve using energetic materials and large amounts of electrical power to create very high pressures inside of a tube in a very short amount of time, behind the...

Hi all new to the forum here. I'm a cnc machinist here in Austin Texas looking for some mechanical advice regarding the use of stainless steel in high strength automotive applications. Basically, I'm planning on starting up my own little business replicating obsolete and out of production...

Dear Experts, :smile: Sorry if this post is created in the wrong forum. I am not sure how to tell if a metal is chrome plated or stainless steel. Is there a simple way to tell? Thank you for reading. sincerely Ramone

Hello, I am looking to use some stainless steel probes in a septic tank to indicate different water levels. i.e. bottom probe would be 0v then propes further up would be set at 12v and taken to 0V when the water level reaches them. Current draw will be very minimal 2 or 3 mA. The big question...

Hi, I'm constructing a waste water tank of 304 stainless steel plate and I'm not sure what thickness the material should be, the tank is approximately 2750mm x 1500mm x 1750mm What would the ideal thickness be for the 304 stainless plate and would there be any specific areas I should focus...

Hi all, just wanted to find out how is austenitic stainless steel made? Because when you heat the steel above certain temperature, your cementite starts to diffuse out and austenite starts to form, but the thing is this: if you allow the austenite to cool down, it reverts back to cementite and...

If there are magnetic and non-magnetic stainless steels,( Martensitic, Ferritic & Austenitic) because of their different physical properties, then what are the trade-offs ’? For example: Being magnetic is it less durable in resisting rust, scratches ext.) ? Can you mill or roll one...

A soap bar made of stainless steel. You wash your hands with it under running water. 1] Do they have a scientific basis? 2] Do they work? http://www.kaboodle.com/reviews/rub-away-odor-bar

How do you calculate the thickness or gauge of a given metal (304 Stainless Steel for example) for a 36" dia. round, vertical cylinder water holding tank? If filled say the tank would be 25-30 feet tall. No physical pressure (pumps or vacuum) on this vessel (vented to atmosphere). Flat...

We were asked in our Manufacturing Processes class to design a process for the manufacture of AISI 304 stainless steel sheet. Starting with hot rolled sheet 9 gauge (U.S.G.) in thickness and 32” wide. The final product is required to be 30 gauge (U.S.G.) in thickness and 32”. Our design needs...

Why does the magnetic field increase significantly when stainless steel is placed behind a magnet? "B (flux density): This is the measurement (in Gauss or Tesla) you get when you use a gaussmeter at the surface of a magnet. The reading is completely dependant on the distance from the surface...

I have a bolt (13 kg) of stainless steel (1650 cm``). How much will this weight in sea water? Thank you in advance!

Is stainless steel magnetic?

Hi I am doing a project on powder metallurgy. I have to design a sintering process for a component. The component is already in production it is the Hego boss (o-ring)on exhaust systems. I have a problem on finding a sintering curve for the material stainless steel 409 Cb, (some kind of...

Okay I am not sure if this is going to make sense to you but please work with me. If i had a rectangular frame of t304 stainless steel 90 feet long and 102 inches wide with supports holding it off the ground at each corner and one support on each 90 foot side in the middle, so theyd be 45 feet...

Hello there, I have a supplier in Turkey making a part for me,which is a small threaded bar(30mm) with a smooth domed head(kinda like a bullet with threads up the side).I was hoping to use 330 stainless steel which is what the part is currently made from.Our supplier is finding it hard to...

Is Chrome or Stainless Steel resistant to corosion by salt and/or acid?

Homework Statement a thick walled tube of stainless steel, ks=19W/m.K, with a 2cm internal diameter and a 4cm outer diameter is covered with a 3cm thick layer of insulation. If the inside and outside wall temperatures are 600C and 100C respectively and the thermal conductivity of the...

Maybe this is more of a chemisty question but I have found that stainless steel is not magnetic. I can only reason that this would be if the Fe (iron) inside the steel is actually bonded with the other components of steel thus making the 3d spins useless to become aligned. i did a search and...

is tempering the correct heat treatment for automotive panel? coz I've seen different version of heat treatment.. some books said tempering, website said (key to steel) said case processing/ annealing (seldom quenching and tempering), actually which one is correct? actually i'd prefer...
