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:how to make a unique piece of steel?
If you're looking to make steel stronger, I can suggest 2 things: 1. If you're actually smithing the steel yourself, and forging it from hot liquid metal, then if you can get ahold of some Carbon (i have no idea where you can get some), you can add it to the molten steel to make it stronger. Sword Smiths did it all the time back in the Dark Ages. (you'll have to look up the exact Science and Process of how to do it) 2. There's a treatment for steel called Tempering. If you Temper the steel, it makes it stronger. You do this by 1st Forging what you're making. In this case, I'll use a sword. Take the Sword and re-heat it (i dont know the exact temperature) until it glows-hot. You can use a blast furnace, a campfire, or any other extreme-source of heat. Some companies use molten Salt - yes, the Condement, and dip the sword in it until it's glowing-hot. Now you have to super-cool it. This is simple, all you need is Ice water. Submerge the Sword in it, until it's cool to the touch. Now toss the Sword back into your source of extreme Heat. Get it glowing hot, and then take the sowrd out. Set it aside, and let it cool naturally. Once it's cooled, it's TEMPERED, and alot stronger. NOTE: If you stop at the ICE-WATER stage, you'll only succeed in making your Sword BRITTLE. You MUST Continue the Process once Started. - Hope this helps.
Q:How much is 18k steel and gold worth?
If you use a Gold Calculator you can find out how much it is worth.
Q:why do ships of steel float?
Believe it or not - A steel boat floats for the exact same reason all boats float. And the very best - easy to understand explanation of this (with pictures) is at the link below.
Q:How is steel coloured?
Steel can be plated(Chrome),Blackened(Black Oxide),Powder coated(color of your choose).All of this is done to prevent rust.All of these aforementioned processes can be worn off through being used.I suggest polished Stainless steel.
Q:Is Grade A Surgical Steel...?
Perfect! 3
Q:STAINLESS Steel....?
Stainless Steel is named that because when compared to untreated steel it is virtually stainless. It is virtually stainless, and harbors very little germs and bacteria. That is why it has been the standard in the food industry for years.
Q:What makes Steel stronger than Iron?
Cast Iron' is typically brittle, while 'Maleable Iron' has a small percentage of carbon which allows it to be hammered and formed. Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron. Steel is a crystalline structure of iron molecules interspersed with carbon molecules. This is properly known as cementite. The hardness and malleability of steel depends not only on the carbon content, but on how the carbon and iron molecules are arranged to one another. Internal stresses in the steel's crystalline structure will increase or decrease depending on the temperature it is subjected to and the rate at which molten steel is cooled. This 'tempering' can increase the strength of the steel at the expense of brittleness.
Q:When does steel start to Warp?
Steel will only warp due to temperature under two conditions: 1. It is not heated evenly - in this case, the hotter parts will expand more than the cooler parts. 2. There are internal stresses in the steel (often from welding or cold-working - as an example, an I-beam or C-channel is usually hot worked, but some cold work can happen, so they can sometimes warp if you heat them ). This means that the steel won't warp due to temp if it's not 1 or 2. However, it could soften and fail if it has a load on it. As for softening, it really depends on what steel alloy you're looking at. Some steels (mainly the expensive alloys) don't really change until above 400 C (750 F), but mild steel really starts to weaken around 150-200 C (300-400 F) Rajashekhar has a point when it comes to forging. Steel isn't really soft enough to forge properly until above 1000C (1830 F), but if you're worried about using steel in a higher temp situation (like around a blast furnace or industrial oven), then make sure you choose a steel that has been rated to work at that temp.
Q:can i heat treat and temper ASTM A36 steel?
A36 is plain carbon structural steel. A36 could almost be considered junk steel. It is not suitable for cutting tools in any respect, as it is far to soft to hold an edge. A36 generally cannot be heat-treated, A36 can only be strengthened by cold-working, and even then, only up to about 60,000 psi. Heating the steel will only make it softer. The only real virtue of A36 is that it's easy to work with, it's easily cut and machined and it is very easy to weld. This is good for making steel structure, but not for knives. Probably the most popular material for knife blades is type 440C stainless. 440C is easy to work with in the un-treated state, and the heat treatment procedure is relatively simple.
