A steel Ballard is a  steel encased concrete poles about 3 Feet high and about 2 feet in diameter which large ship tie off too when in port.

First of all you would find the first part of you question in the manual. The second part is documented in the Manual of STEEL CONSTRUCTION "Allowable Stress Design" Ninth Edition. and the third part is called an M.T.R. This is the birth compasition of the metal used to make the beam which gives you the carbon hardness and rating of that beam. \nGood luck,\nChris

In 1962, Republic Steel of Cleveland approached the Steelers and suggested that they consider the Steelmark, the insignia used by the American Iron and Steel Institute (AISI), as a helmet logo to honor Pittsburgh's steel heritage. The Steelmark logo, a circle enclosing three hypocycloids (diamonds with inward-curving edges) and the word STEEL, was created by U.S. Steel Corp. (now known as USX Corp.) to educate consumers about the importance of steel in their daily lives. [blockquote]The colors were chosen to promote the attributes for steel: yellow lightens your work; orange brightens your leisure; and blue widens your world. The logo's meaning was later amended to represent the three materials used to produce steel: yellow for coal; orange for iron ore; and blue for steel scrap.[/blockquote

S690/WTP80C:\n\nS690 is a reference to a high-strength steel.\nWTP80C is a chemical composition for a Chinese-produced "equivalent" steel, would be my guess.\n\nComposition of WTP80C (quantities are in percent):\nCarbon < 0.18\nSilicon 0.15-0.35\nManganese 0.6 - 1.20\nPhosphorus < 0.30\nSulfur < 0.030\nCopper 0.15 - 0.50\nChromium 0.70 - 1.3\nMolybdenum < 0.60\nBoron < 0.006\nNickel ... unlisted

well, do you have access to a stone saw?  Look for crystalline structure inside of the object.  Also determine it's specific gravity, and you can look it up on the jpl web site.  First though is it metal, magnetic? Or a rock.

Try contact the ASTM Directly - it's one of their specs.\n\nA311/A311M-04 - Standard Specification for Cold-Drawn, Stress-Relieved Carbon Steel Bars Subject to Mechanical Property Requirements.\n\nwww.astm.org\n\nThanks!!! Morgan x :o)

Because steel is cheaper and mass produced.

The metal is corrosion-resistant. The catalytic properties of the six platinum family metals are outstanding (a mixture of hydrogen and oxygen explodes in the presence of platinum). For this catalytic property, platinum is used in catalytic converters, incorporated in automobile exhaust systems, as well as tips of spark plugs.\nPlatinum possesses remarkable resistance to chemical attack, excellent high-temperature characteristics, and stable electrical properties. All these properties have been exploited for industrial applications.

You should know, AS A STRUCTURAL ENGINEER, that steel has a melting point at about 2750 degrees farenheit.\n\nYou should know, AS A STRUCTURAL ENGINEER, that steel loses half of its strength at about 1100 dg farenheit, and at 1800 dg F it loses about 90% of its strength.\n\nJet fuel does not burn hot enough (800-1500 dg F) to MELT the steel, and the towers did not come down because the jet fuel melted the steel.  The jet fuel burned off in a matter of minutes, but it was the ignition source for other combustible material, that heated the steel enough to weaken it and cause the structural failure.  Official investigation reports that pockets of the rubble were burning at about 1832 dg Farenheit.\n\nAS A STRUCTURAL ENGINEER, you should also know that a "pancaking" EFFECT is the result of structural failure of the floor support system, and can be caused by many forms of structural catastrophe, including weakened support by fire, physical damage, etc.  The CAUSE of those things can be planes slicing through steel, fires, and yes demolition teams destroy support systems to bring down buildings as well.\n\nJust because the effect is the same doesn't mean the cause is the same.  Of course, you already knew that because YOU'RE A STRUCTURAL ENGINEER, right?\n\nAS A STRUCTURAL ENGINEER, you should know how the towers were constructed and study the report before you make conclusions agreeing with a conspiracy theory.\n\nDo your homework with facts, not conspirasites.  It will serve your career better.

Obviously, Cobalt, Iron & Nickel.But its the alloy Alnico used to make permanent magnets.

It's probably steel, since that offers a good combination of strength, light weight, and low price.  Have you tried a magnet on the metal parts of it?  \n\n If it's not steel, maybe it's stainless steel (which tends to be non-magnetic depending on the alloy) or aluminum, but those are quite a bit more expensive than regular sheet steel.

A steel is an alloy of iron (the base metal in a steel), carbon, Si,Mn, and some other elements. The melting point for each different alloy depends on its composition. In general, the melting point decreases with increasing the carbon concentration. For an eutectoidic steel (0.8%C) it is about 1450 degree Celsius, for a high-carbon steel is 1400 degree Celsius, and for low-carbon steel is 1490 degree Celsius. When u have added other elements in the steel, these temperatures can vary.
