About INCONEL-600
INCONEL® (nickel-chromium-iron) alloy 600 (UNS N06600/W.Nr. 2.4816) is a standard engineering material for applications which require resistance to corrosion and heat. The alloy also has excellent mechanical properties and presents the desirable combination of high strength and good workability. The limiting chemical composition of INCONEL alloy 600 is shown in Table 1. The high nickel content gives the alloy resistance to corrosion by many organic and inorganic compounds and also makes it virtually immune to chloride-ion stress-corrosion cracking. Chromium confers resistance to sulfur compounds and also provides resistance to oxidizing conditions at high temperatures or in corrosive solutions. The alloy is not precipitation hardenable; it is hardened and
strengthened only by cold work. The versatility of INCONEL alloy 600 has led to its use in a variety of applications involving temperatures from cryogenic to above 2000°F (1095°C). The alloy is used extensively in the chemical industry for its strength and corrosion resistance. Applications include heaters, stills, bubble towers and condensers for processing of fatty acids; evaporator tubes, tube sheets and flaking trays for the manufacture of sodium sulfide; and equipment for handling abietic acid in the manufacture of paper pulp. The alloy's strength and oxidation resistance at high temperatures make it useful for many applications in the heat-treating industry. It is used for retorts, muffles, roller hearths and other furnace components and for heat-treating baskets and trays. In the aeronautical field, INCONEL alloy 600 is used for a variety of engine and airframe components which must withstand high temperatures. Examples are lockwire, exhaust liners and turbine seals. INCONEL alloy 600 is used in the electronic field for such parts as cathode-ray tube spiders, thyratron grids, tube support members and springs.The alloy is a standard material of construction for nuclear reactors. It has excellent resistance to corrosion by high-purity water, and no indication of chloride-ion stress-corrosion cracking in reactor water systems has been detected. For nuclear applications, the alloy is produced to exacting specifications and is designated INCONEL alloy 600T.

How long does it take for moonlight to reach the earth?
Light travels through space at just over 186,000 miles per second. The moon is just under 250,000 miles from Earth, so light from the Moon's surface has to travel more than one second (about 1.3 seconds) to reach us.
The astronauts left reflecting mirrors on the moon. By shining a laser beam on those mirrors from Earth, and measuring the time (less than 3 seconds) it takes to see its reflection, the length of the round trip can be easily calculated to within a few inches!
Which planet rotates so fast that its day is only 10 hours long?
Both Jupiter and Saturn have days that last about 10 hours. Jupiter has a period of 0.410 earth days or about 9.84 hours and Saturn has a period of 0.426 earth days or about 10.224 hours.
