Q:Besides stainless steel....?
silver, white gold, and platinum match the color of stainless steel the best. they last long, too ;)
Q:Pros and cons of stainless steel firearms?
stainless steel is a alloyed steel that resist rust and corrosion. show it enough salt (sea spray or sweat) and it will pit Stainless steel goes all the way through ...it's not a coating like nickle-plate. the inside of a stainless barrel is stainless and they hold up just as well as carbon steel barrels. Extra money? Stainless is pretty popular in new production and the price is not that much different than comparable guns in blue. Oil OK... they do hold up better to salt and sweat than bluing...and there is not coating or plating that can wear off. Down side... the reflect light. Some can be a bit to shiny for some situations.
Q:Carbon Steel/ Stainless Steel knives?
There are different grades of Carbon Steel. A good grade is much harder than Stainless Steel and will stay sharp longer. It is also many times harder to get an edge on than Stainless Steel. I have had both and prefer the Stainless Steel because eventually the Carbon Blade does get dull, and you will wear out a Whet Stone trying to put the edge back on it. The Stainless Steel holds an edge an acceptable amount of time and is easier to sharpen when the time comes. Putting either knife through a can opener sharpener will ruin the edge and make it almost impossible to put another edge on the knife. Look closely and determine the angel of the bevel, then lay the knife bevel flat on a good whet stone and try to take a thin slice off of the stone. Turn the knife over and do the other side so you keep the edge centered on the blade. Keep turning the knife over and taking thin slices until it is sharp. Dress with a good quality sharpening steel.
Q:Cast iron Vs. Stainless steel?
For strength, cast iron (that's why OEM exhaust manifolds are made out of it). For performance, stainless steel. For one, stainless steel headers are lighter than cast iron ones. Then they come in multiple arrangements, (4-2-1 or 4-1 for 4 cylinder motors). The down fall is strength. Hit a pot hole with the collector of a stainless steel header. It's going to have a nice dent in it.
Q:what are steel bollard?
There those short yellow post's the are too short to see when you back into them.
Q:how is structural steel cut?
I am going to take a slightly different approach. Once the structural steel is manufactured and then brought to the fabricator, not much heat is applied to the steel. It is normally punched, sheared or whatever buy the use of a lot of heat on it is normally not allowed due to the change in the properties of the steel. Once in the field to be erected, the cutting or welding on it are held to absolute minimums and most of the time not allowed at all.
Q:Which is a greener building material, steel or wood?
In okorder.com/.. Properly managed then wood is a fully sustainable and green building material and from an environmental perspective is better than steel. However, it doesn’t possess the compressive strength that steel possesses and it can’t easily be worked or formed into structural components like steel can.
Q:Soldering Steel Wire?
You can indeed by using the correct flux as normal soldering fluxes as used by plumbers will not work. I believe to solder steel it requires an acid flux which will corrode copper so when its done make sure its well cleaned afterwards and if possible apply a corrosion proofer afterwards ie paint or even petroleum jelly. I am curious as to why you would want to solder wire to a steel nail.
Q:What are the best kind of steels for a knife?
That one they use for the Army Combat Knife, I forgot what its called but Its a good one if your going to use it for camping.
Q:Stainless steel sword?
Ya it could kill someone if it was sharpened enough but from experience stainless steel swords don't get as sharp as Carbon or higher grade steel. Not to mention it would probably bend if you hit someone with it all the way. Hell the one I let some people who were chopping a bush ( just a normal bush ) they were playing around and it got bent. I'm going to say I can't suggest a stainless steel sword for anything other then handing on your wall. Not even going into the whole If you use a sword for self defense is it considered self defense? debate. It's a sketchy situation not to mention you would need training with a sword to actually use it without it just getting brushed off.
