Q:Is a ring made of steel good?
Steel rust is brown not green! Very much expected to be of one type of stainless steel, and you should have no problem.
Q:Why should you heat thicker steel before welding?
ok dont listen to bob the builder down there, u preheat thicker steels to draw moisture out of them. take a propane torch to something exposed to just atmospheric air around 3 inches thick and the water will literally pour out of it. do u want that in ur weld? no. so u preheat to draw any moisture or contaminates out of the base metal. good luck.
Q:how to tell if its stainless steel?
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.
Q:mild steel?
The density of mild steel is about 7.8 gm/cc. 1 cubic metre is 1,000,000 cc, so it weighs 7,800Kg - 7.7 tons.
Q:Best affordable steel combat knife?
Sorry, probably aint gonna happen in that $ range. How big of a blade will effect the steel selection. For instance I have one I forged from 52100, a most excellent steel better suited for 5-6 blades. For larger blades either 5160 or L-6 can make an indestructable blade. For 5 and under D-2 is about as fine a steel as you can get. No blade made from these will come cheap, L-6 is only available from custom makers. Save up your money, expect to pay 100 - 200 for a well made blade. You pay cheap prices you get cheap workmanship.
Q:About hydrolics which one used in steel melting shop?
The correct spelling is hydraulics. I haven't heard the term steel melting shop you probably means a foundry or a steel mill The most obvious example i can think of is hydraulic-operated fork lifts. Hydraulic cylinders are used to lift the forks and to tilt them upwards or downwards. The valves are coneccted to levers next to the steering wheel. Hydraulic pressure is supplied by a hydraulic pump driven by a propane or diesel engine. In some forklift designs the wheels are also not connected directly to the engine, but driven by hydraulic motors. There are also a large variety of machines used in steel mills and metalworking companies to cut and shape metal parts. for example, press brakes, plate cutting shears, stamping presses, hole punch machines, drawing presses, etc. These types all operate in much the same basic way. They use a very large cylinder or group of cylinders to apply many tons of force to different kinds of metal working tools.
Q:What is the best butcher's steel?
It's okorder.com/... For best results you'd need a smooth steel, which is outside of your budget, but for all practical purposes fine grit ceramic sticks work the same and they also work for super hard Japanese kitchen knives, since the butcher's steel is softer than the steel in those knives. Get something over 1000 grit and use the same motion as with the steel. Just very light pressure and try to match the edge.
Q:WHAT ARE THE WAYS THAT YO COULD PREVENT STEEL FROM RUSTING WHEN IT IS EXPOSED TO WATER? SALT WATER? VINEGAR?
Coat it in molten plastic, or use stainlessteel
Q:problem cutting steel?
Your blade was overheated. Change it into diamond blade shall do.
Q:How did the growth of the steel industry influence the development of other industries?
At least three ways: 1. Steel as a material that other industries could use to do things that couldn't be done before (for example, construction (skyscrapers, long bridges, etc.)) or could now be done at much lower cost and hence increased the size of the industry (automobiles, bearings, etc.)
