Q:why does steel rust?????????????
Steel is made adding carbon to iron.The iron in steel reacts with oxygen in the air, producing ferric oxide(Rust).
Q:types of steel.......?
Don't know too much but I know combat grade katanas are made out of folded carbon-steel. Could also look into industrial steel grading systems if you are looking for something to show off at a martial arts tournament or something.
Q:Best Quality Steel...............!!?
Please specify what kind of steel, is it structural steel (like wide flange, channel or Z-section) or reinforcing steel? For structural steel, all steel members that passed the requirement of ASTM-A360 are the best quality. While for reinforcing steel, it should passed the requirement of ASTM-D3963 for epoxy coated and ASTM-A615 (Grade 60) for deformed bars.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
The length of the roll is related to its width and thickness, but not to the extent of the zinc layer.
Q:pedal steel guitar...?
I agree with everything that Lester said. Another thought is to consider starting on a lap steel guitar rather than a pedal steel - its related, a little easier to learn on, and less expensive. Once you get proficient on the lap steel, you can move up to the pedal steel. Good luck!
Q:Will painted steel rust?
Painting a piece of steel will coat it with a protective layer, causing it to not rust (not get oxidised). Aluminum does not rust.
Q:How to temper steel? ?
Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
Q:serious question! Dual-phase steel?
Dual Phase steels refers to a distinct group of alloys which are used for automotive bodies. These were developed to give improved deep drawing (for shaping) and strength while on the road. Most of the work was started at the same time in the 1970s as a response to the oil crisis (history repeats!) with SSAB in Europe, US Steel and British Steel leading the way. There are many variants of the dual phase alloys prefered by each of the auto manufacturers. The work on these steels led the way for TRIP (transformation induced plasticity) steels, rephosphorised steels and HSLA (high strength low alloy) steels. There is a distinction between these steels and duplex steels which typically refer to austenitic/ferrtic stainless steels. Also be aware that everyday low carbon steels with 0.1%-0.6% carbon will have a ferritic/pearlitic structure but are not considered to be dual phase So to summarise: Who - major steel companies worldwide When - from about 1973 onwards (up to around 1977 when the developments went in other directions) Where - Europe, USA and Japan (but I'm not sure who it was in Japan doing the work)
Q:Fallout 3 broken steel question?
Broken Steel fixes the original ending of the game so that you can continue past the end and continue exploring. The Broken Steel missions also take place after the original ending of the game. One way you can tell if Broken Steel is working though is if you are finding enemies added with Broken Steel (Super Mutant Overlords, Hellfire Enclave Troops, and so on), and if you can level up past level 20 and get new perks added between 20 and 30. You can even see all of these new perks any time you level up, so next time you level up, scroll down and see if there are new perks below the level 20 perks. If there are, then Broken Steel is working properly.
Q:On how to reinforce steel coils in a container
They can be strapped to the floor with wire ropes and locks
