Go ahead tell me about it.  (This thread is left vague on purpose so that it can contain a multitude of answers from a wide variety of different fields such as military, eating utensils, car parts, jewellery, etc.) |
The titanium spork is the tacticoolest eating accessory ever!

 See, the hardest metal is on a treadmill located 0.9bar from the greatest game. Here's the math to explain it:  Now if you'll excuse me, I have to gb2/b/ to feed my dog. Oops. Looks like he's not hungry.

It can't be hardened over about 42-44 Rockwell without getting very brittle, so it isn't used in barrels (they use steel liners) nor is it used for certain highly hardened parts (trigger components). This is partly why we don't see many titanium knife blades,either. |

Ti makes a beautiful white spark when you throw the grinder to it steel is generally a boring red you can get Ti to spark with a decent file If you get it hot enough Ti will burn quite vigorously a pound of Ferro-Ti is worth about 3.90$ right now a pound of premium steel right now is worth about .14 cents above are scrap prices, not new production stock. |
Ti powder can be an explosive situation.. |
omg  Damn treadmills! |

I know that at just as strong as steel and twice as strong as aluminum while being 65% heavier than aluminum and 45% lighter than steel, I wish gun manufacturers would wake the hell up and start making us some new titanium rifles and pistols. There have been some titanium AR lowers made but not any uppers that I've seen and I sure as hell would love to replace the upper and lower receiver of my POF piston AR with a high quality matched titanium upper and lower receiver. A titanium charging handle would be great too. I've also felt but not mentioned that if Magpul designed in a strong skeletal titanium frame for the upper and lower of their Masada we'd probably have one seriously strong, while still light, all around ass kickin new rifle to break through the coming years with.  You listening Magpul?  A little Titanium info |

Neither a countycomm titanium moneyclip nor a titanium Tissot T-Touch watch will set off metal detectors. This may surprise the TSA. Titanium rings apparently cannot be resized. The aforementioned Tissot weighs about the same as a much smaller stainless steel Doxa pilot. The Tissot being a gigantic hunk of gizmo, this is good. Titanium is brittle enough to surprise the heck out of a lot of people when it fails. |
Brittleness in any metal has alot to do with the heat treating. The temper needs to be right with the balance of the softer core for toughness and the harder outside for wear resistance. That's been a problem from what I've known of late manufacturing of titanium but has been worked out by more than few. The Army ran into similar problems from I know in development of titanium tank hatches. Army titanium hatches A factor of it's higher cost also has been related to the fact that there weren't many around that could machine and manufacture it properly. Investment and development should help that in time, but I feel the availability of it in elemental amount around the world and advantage it has in similar steel strength while lower weight merits it further progression of use in the future. |
| Alloys of Titanium with Nickel and Copper create "Shape Memory Alloys" |
 Ok... you owe me a new monitor. |
well if they did that, they would sell less parts, since it would last longer.... Ti barrel would be pretty sweet! |

First off its impossible to make general comments on "steel" because there are so many types of steels ( carbon steels, low alloys etc ) Titanium : titaniums claim to fame is actually not necessarily its strength ( more on that later ) but its weight and corrosion resistance. Titanium is about 40-45% lighter than carbon steels . Titanium is also extremely corrosion resistant ( acids / salts etc ) . This is one reason titanium alloys are used in medical implants ( dont want a rusty pin in you ) Titaniums Tensile / Yield Strength There is a common misconception that titanium is super strong. It may or may not be First off most Titanium is actually titanium alloys , similar to most aluminum you see is not pure aluminum but rather alloys of aluminum CP ( commercially pure ) titanium can be as low as 35 to 70 ksi TS . To put this into perspective, hardened aluminum would be about 45ksi to 70ksi , high strength steels may be from 70 to 120ksi. So really these are unimpressive when it comes to mechanical properties. Often this is used for surgical parts, heat exhangers, jewlery etc where high strength is not required Where Titanium is actually impressive is when its alloyed. Common "Alpha Alloys of Titanium " are 3Al-2.5V ( 3 aluminum 2.5 Vanadium ), 5Al-2.5Sn etc . This improves on strength and toughness of the CP aluminums. Strength levels are that of low alloy steels ( chrome moly, chrome nickle moly etc ). Typically 100 to 120ksi Often these products are found in aircraft parts, biclycle parts etc The next step are the "Alpha Beta alloys" of aluminum. Common examples are 6Al- 4V ( 6aluminum 4 vanadium ). Here the strengths are very impressive, reaching 180+ ksi . These titaniums are far stronger than most low alloy steels , yet retain good ductility and corrosion resistantce. Typically you see these in aerospace parts, chemical processing, surgical implantes etc Lastly we have the beta alloys such as 10V-2Fe-3Al where the strengh levels approach 190ksi . Needless to say, this is far stronger than typical non alloy steels For comparison, quenched and tempered plate such as T-1 is about 110ksi . Low alloy steels such as chrome moly ( SAE4130) would be about 100ksi . Chrome nickle molys ( 4350s ) however can approach 190ksi Conclusion Bottom line is some Titanium and alloys off titanium are no stronger than alloy steels. On the other hand some alloys of titanium are stronger than some alloy steels . All titanium alloys are lighter and significanlty more corrosion resistance. Some steels are very low in tensile strength ( 45ksi ) but some alloy steels exceed 190ksi Titanium is lighter ( 45% ) and always better corrosion resistance than steels and its alloys Titanium and its alloys are much harder to machine ( tendency to work harden ) and harder to weld ( need trailing gas / inert chambers etc ) than carbon steels and low alloys steels Were Titanium is not the best choice is extreme temperature ( high temp creep strength ) . There nickle alloys ( Inconel etc ) are a better choice. Example are turbine blades are typically nickle alloys |
Is anyone else confused?

from wiki... The Riddle of Steel is inspired by several references in the movie Conan the Barbarian, including a line of dialogue in which the villain, Thulsa Doom, asks the captured Conan, "What is the riddle of steel?" Doom answers this question by explaining to Conan that the true strength of steel is in the hand that wields it – in other words, it is the resolve and commitment we bring to a task, not the quality or quantity of tools we use in performing it, that is the most important factor in determining success. This theme strongly influenced the design of Riddle, most particularly in the implementation of Spiritual Attributes. |

I have 2 framing hammers. #1 24oz california framer with a steel head and an 18" wooden handle. I call it my pocket maul. The waffle is worn off. It cost me $24. #2 14oz california framer with a titanium head and an 18" wooden handle. I call it my cadillac. The waffle is still crisp and defined. It cost me $99. Both are exactly the same size. Both swing like barry bonds. The titanium one swings like barry on the juice. The 24oz steel one is alot heavier than the hammers most carpenters will carry. I think the titanium one wins hands down, flat out. |

Ti is used extensively in surgical reconstruction because it is the only metal that when the surface oxidizes, is fully biocompatible and does not trigger a foreign body response. It is used in plates, screws, rods, and having no ferrous content, will mot trigger a metal detector, nor prevent a person from getting an MRI. When Ti is combines with Nickel, it creates a shape memory metal, another totally cool material also extensively used in medicine. |
No, the resolve of the person to complete the task at hand is more important than the tools used to complete the task. If you have not seen the movie, just after this dialog he beckons one of his servants to come to him. Though she is on a cliff 100ft above them, she shows her resolve and jumps off the cliff, landing near him. Regardless of the lack of tools, she completed the task, that’s resolve. |
