FAQ

I do a lot of scrapping and would like to be able to separate stainless steel from regular steel. The magnet test doesn't always work since stainless can be magnetic, but what are some ways that I can for sure tell the difference? Or even something like a sound that they make that may help me to tell the difference.

Stainless steel uses chromium in its mixture to thwart the affects of corrosion. General steel, or carbon steel, is generally almost completely iron and is used for far greater applications than stainless steel. Stainless steel is used mostly in kitchen appliances, utensils, etc... The best thing I can come up with is to find a way to measure the chromium content of the steel you are looking at. If it's around 3% chromium, it's probably standard steel. If it's somewhere between 10-15% chromium it's probably stainless steel (or even 4% plus). I can't tell you a fast and quick way to test the steel because from my research, it appears there are as many grades and allows of steel as there are uses for steel! There is one test I've seen for home testing surgical steel which is a higher grade stainless steel, that is to put scotch tape on one section of material then soak it in water for a 24 hour period, then let it air dry for 24 hours. You remove the tape and lightly polish the exposed areas to see if there was any discoloration or pitting on the exposed area. This test is mainly for surgical steel jewelry, however stainless steel is supposed to resist rusting more than standard steel, hence it might work for other steel types as well. You may have to read some of the other links below to get some other ideas on how you can test steel to see if it is stainless.

I made a wood crossbow body but all I need is a bow which I want to be metal. I've used a thin steel sheet that I cut to appropriate size but when it bent with the string strung, it never went to original shape after being shot. I used a slightly thicker and it wouldn't bend at all. Anybody know what thickness and type to use? Any real answers are very appreciated. Thanks.

You are trying to use plain carbon steel which only can be bent a little bit if it is to return to its original shape. You have to use spring steel or high carbon steel that is intended to be bent a lot and still recover to its original shape. Most people making crossbows with metal bows get a piece of steel from a leaf spring of a vehicle and grind it to shape. A steel bow cross bow almost always needs a very strong trigger mechanism and a miniature wench to pull the steel bow string into position. You might be better off making the bow of wood.

Coil slitting, also known as coil cutting, involves the process of cutting large metal coils into narrower strips. However, there are several challenges associated with this process. One challenge is maintaining precision during slitting, as any deviation can result in uneven strip widths or poor edge quality. Another challenge is managing the tension of the coil throughout the slitting process to prevent material distortion or breakage. Additionally, handling and transporting the slit coils can be challenging due to their length and weight. Overall, ensuring accuracy, maintaining proper tension, and effectively handling the slit coils are some of the key challenges faced in coil slitting.

Steel is no doubt a better constructin material but it is only in practice in developed country.i would like that we should high lights the benifits and negatives of steel to make the steel more clear as a construction material.Hope some expert to address this topicMD

Steel Structure considered as the most efficient and fast in completion of any project, specially the high rise buildings, also the logistics during construction is less complicated than the normal methods, Steel Structure has so many advantages vs the disadvantages, and highly recommended for commercial buildings

The maximum weight capacity for a steel coil lifting device can vary depending on its design and specifications. It is important to refer to the manufacturer's guidelines and specifications to determine the specific weight capacity for the lifting device in question.

Building the bulwurk, general use on trawlers. What kind of steel is best suited.

How big is your trawler going to be and what use, The ones you see off the Alaska Coast or a Gulf Coast Shrimper? My preference in today's economy would not make sense and that is Aluminum.....not steel at all, maybe even Fiberglass, but $$$$ talk so Steel is cheaper, but you need to know what you are doing. The designer of the hull should have specified the right /preferred grade. It today's world there are many more choices available. You use a mild steel, most often grade A or B, but some applications call for grade D. Check your blue prints and list of materials. Edit. Ok I understand. There are 2 ways to go. One is use a relatively cheep steel and use higher cost epoxy primers and paint, often requiring special surface preparation just before priming, or two, using a much higher cost steel with more chrome and nickel in it. Grades that begin with #3xxx These are weldable with rods that are available, and can be welded directly to mild steels. However these are 3X the cost. If your a Shrimper, I'm guessing gulf coast. I worked with several boat yards in the 70's installing spray urethane foam for insulating there holes. So I've been around lots of small yards from Florida to Texas. I'd call the nearest steel warehouse and ask what they would recommend. You might find what you want at a scrap yard. I've lucked out several times picking up 1/4 plate scrap$ and I'd bet the scrapyard guy would know just what you need. I know there are places to get what you need in Mobile and New Orleans. Good luck!

Steel being my favorite type, I just picked up Heart Gold today, my gf got Soul Silver...I was wondering which steel types are available and somewhat easily obtainable in HG (and/or what is the earliest steel type I can get?)

easiest would be magnemite the good steel types will require some more effort My favorite steel type, scizor, needs a trade with a metal coat... And you don't find metal coat until halfway into the game There's also steelix there aren't that many steel types in the johto generation. There are some good ones in the hoenn so you could transfer from there

iam talking abt carbon steel of composition:-C=0.15wt% Mn=0.60wt% P=0.035wt% S=0.04wt% Cu=0.20 (min)wt%....

The composition of the steel is almost tertiary to many other considerations, except that there are certain elements and percentages of elements which tend to affect the crystaline structure in the steel. The most basic question is whether the crystaline arrangement of atoms in the steel is martensitic or austenitic, and many factors influence that. In general, martensitic structure is magnetic and austenitic structure doesn't respond much to magnetic fields, but there are varying degrees of martensitic and austenitic -- there is never a pure state.
