Q:Is 30CrNiMo8 a kind of high alloy STEEL?
Yes,30CrNiMo8 is a high grade alloy steel. *These steels generally contain higher carbon concentration (0.25%). As they are hardenable their mechanical properties can be tailored to specific needs by suitable adjustment of the annealing temperature. Finished products can be hardened to have a high surface hardness in combination with a tough and ductile core. The mechanical properties increase with increasing carbon concentration. Cr and Ni add additional improvements in properties. The Mn grades are a little cheaper. V and Mo add improved temperature resistance. The grades Cxx are developed for less stringent quality requirements but are cheaper.
Q:How do I clean stainless steel?
Use stainless steel cleaner which you can get at hardware stores, Home Depot, and Lowes.
Q:Aluminized Steel same with Stainless Steel 409 & 430?
Alloy steel is a stainless steel. The differences between the two are the composition of the metal. Alloy steel is steel with usually less than 5% of other elements, like molybdenum, copper, chrome while stainless steel is a steel with at least 10-11% of chromium.
Q:what is the advantages in using mild steel as raw material in an experimental machining?
*Mild steel is ductile and can be easily machined. Generation of heat is less than that of steel machining.So, the tool can have better life and you can do more machining. Cost factor is of prime importance as other steel are more costly than Mild steel. Mild steel, a grade of steel that does not harden when heated and chilled with cold water, so further machining can be easy. Mild steel is easily available.You will find it in your scrape yard. No need to change the tool repeatedly and no special tools are required for machining. Above is the comparisation between alloy steel,SS and superalloys. Cutting speed and feed does not required special skills.
Q:Is blue steel stronger than stainless steel? i heard it is.?
Blue Steel is definitely stronger than stainless. Le Tigre and Ferrari are too. However, nothing compares to the strength of 'Blue Steel' to a non-ambi-turner.
Q:big steel drum grill?
yes that keeps the fat from dripping on the burners - just try it - it works.
Q:Silver OR Steel Jewellery.?
STAINLESS steel is fine. It is the modern alternative. Whether it is seen as a `cheap` necklace depends on the quality of the necklace itself in this case, not what it is made of. At £110 it should be a well-made and a quite original piece. You should have put a link showing it . Stainless steel will not rust, it`s washable, and will keep it shine forever. My own guess (based on the limited info you have supplied) is that it sounds like a very acceptable gift.
Q:Conductivity question for electricity through stainless steel?
I can only guess. I can't even tell if you are plating some other metal with copper OR if you are plating copper with some other metal. you state that you use the copper clamps only to confirm the current, but I don't see how that works. I suspect that the plating current actually goes through these clamps, so conductivity is very important. But, the conductivity of SS is about 1/5th that of copper, so that will definitely have an effect, and not a good one. .
Q:Can I make a homemade blacksmith forge from an old stainless steel washing machine drum?

Q:Can I put nylon strings on my steel string acoustic guitar?
No, a steel string guitar is built and braced for the greater tension of steel strings, which means it's too heavily built to respond properly to nylon strings. It would sound awful. Besides, the slots in the nut are too narrow on a steel-string, the action is too low, and the bridge is made for ball end strings (most high quality nylon strings are plain end). And you would have to turn the narrow string posts on steel-string tuners forever to get anywhere with stretchy nylon strings.
