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 do you rate steel?
Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Its very high carbon content is responsible for these characteristics, which make 440C particularly suited to such applications as ball bearings and valve parts. Grades 440A and 440B are identical except for slightly lower carbon contents (0.60 - 0.75% and 0.75 - 0.95% respectively); these have lower attainable hardnesses but slightly higher corrosion resistances. Although all three versions of this grade are standard grades, in practice 440C is more available than the A or B variants. A free-machining variant 440F (UNS S44020) also exists, with the same high carbon content as 440C. Again this grade is not readily available in Australia. Martensitic stainless steels are optimised for high hardness, and other properties are to some degree compromised. Fabrication must be by methods that allow for poor weldability and usually also allow for a final harden and temper heat treatment. Corrosion resistance is lower than the common austenitic grades, and their useful operating temperature range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures. Key Properties These properties are specified for bar product in ASTM A276. Similar but not necessarily identical properties are specified for other products such as plate and forgings in their respective specifications.
Q:Key differences between the term structural steel fabrication & steel fabrication?
Steel fabrication can include any kind of manufacture of steel. Structural steel is a narrow subset which would include, for example, I-beams and would not usually include stainless steel, sheet steel, rolled steel, etc.
Q:quality of steel ..................!!?
The quality of the alloy can be very well be judged by its appearance and lustrous surface. The more luster on the surface the more refine will the steel be. To judge its tenacity and endurance, the alloy can be subjected to a series of procedures involving stress and shock. There are many more scientific methods of measuring the quality of the alloy such as texture measurement technique etc are also employed. In layman’s term the quality can be measured by the hardness of surface, brightness and smoothness of the surface and absence of any depressions or troughs.
Q:Steel or nylon strings?
Yeah, you have some really bad answers here. You don't buy a nylon string guitar because you are a beginner, you buy one because you want to play classical music. You also cannot move between nylon and steel strings on the same guitar. Unless you want to play classical finger style music you need a steel string guitar. Just have extra light strings put on it and you can most likely have the action lowered a bit also, both of which will make it easier on the fingers. But the bottom line is this, if you want to play guitar you will have to go through a stage where you fingers get a little tender. Just keep your practice sessions short in the beginning, like 15 - 20 minutes at a time until the calluses build up.
Q:What are the best kind of steels for a knife?
D2 and O2 steels are nice. They are expensive, but hold an edge extremely well. S30V is nice also. It's a more stain-resistant steel that holds an edge very well. For outdoor hiking/camping knives, it's tough to beat good old 1095 carbon steel. Sure it will rust, but it's tough as nails, not brittle, holds an edge pretty well, and easy to sharpen...and it's pretty cheap. Other steels, AUS8 is an ok cheap steel. It's stain resistant and cheap. AUS6 isn't worth the time or effort. Buck knives does an excellent job of heat treating 420 stainless to become very hard. Their knives are excellent considering 420 stainless is typically soft steel.

Q:whats the average price of wide flange steel W10x30?
The price of steel is increasing daily, so an exact answer is rough. A W10x30 is a fairly common shape and shouldn't be too hard to find. For a very rough ballpark number, say $700/ton (installed price), the piece you require should be in the range of about $250.00 or less as I assume you'll be doing the installing. Please don't take this as the gospel, however. Price varies on location, stock, and availability. Open the phone book and contact your local steel supplier. Because the piece you require is fairly short, you might get lucky and find someone who has a waste piece that length that they will give you a good deal on. --------------------------------------... I just checked the AISC web site to verify the number I quoted above and they posted an article stating that the average mill price had just increased to over $1000/ton in May. The best advice I can provide at this point is to buy the W10 now and don't wait any longer.
Q:truth of steel Sword making?
I am unsure of what the Truth of Steel is, but here is the Riddle of Steel (from Conan) Thulsa Doom: Yes! You know what it is, don't you boy? Shall I tell you? It's the least I can do. Steel isn't strong, boy, flesh is stronger! Look around you. There, on the rocks; a beautiful girl. Come to me, my child... Thulsa Doom: [coaxes the girl to jump to her death] Thulsa Doom: That is strength, boy! That is power! What is steel compared to the hand that wields it? Look at the strength in your body, the desire in your heart, I gave you this! Such a waste. Contemplate this on the tree of woe. Crucify him!
