UNIT WEIGHT OF ISMC

Some times during our Execution,  we suppose encounter the odd size sections like ISMC 250 X 82. We will execute the job but will be claimed ISMC 250 X 80 weight. Self had a same experience in my early days. To avoid this by others self listed the section weight of Channels below

                                                       1) ISMC 75 X 40 -7.14

2) ISMC 100 X 50-9.56

3) ISMC 125 X 65-13.10
4) ISMC 125 X 66-13.70
5) ISMC 150 X 75-16.80
6) ISMC 150 X 76-17.70
7) ISMC 175 X 75-19.60
8) ISMC 175 X 77-21.70
9) ISMC 200 X 75-22.30

10) ISMC 200 X 76-24.30

11) ISMC 225 X 80-26.10

12) ISMC 225 X 83-30.70
13) ISMC 250 X 80-30.60

14) ISMC 250 X 82-34.60

15) ISMC 250 X 84-38.10
16) ISMC 300 X 90-36.30
17) ISMC 300 X 92-41.50
18) ISMC 300 X 94-46.20
19) ISMC 350 X100-42.70
20) ISMC 400 X 100-50.10

CAR A/C

Do You Know? Do not turn on A/C immediately as soon as you enter Your .... CAR!

Please open the windows after you enter your car and do not turn ON the air-conditioning immediately. According to a research done, the car dashboard, sofa, air freshener emits Benzene, a Cancer causing toxin (carcinogen- take note of the heated plastic smell in your car). In addition to causing cancer, it poisons your bones, causes anemia, and reduces white blood cells. Prolonged exposure will cause Leukemia, increasing the risk of cancer may also cause miscarriage.

Acceptable Benzene level indoors is 50 mg per sq. ft. A car parked indoors with the windows closed will contain 400-800 mg of Benzene. If parked outdoors under the sun at a temperature above 60 degrees F, the Benzene level goes up to 2000-4000 mg, 40 times the acceptable level... & the people inside the car will inevitably inhale an excess amount of the toxins.

It is recommended that you open the windows and door to give time for the interior to air out before you enter. Benzene is a toxin that affects your kidney and liver, and is very difficult for your body to expel this toxic stuff.

Steel Type and Uses

There are five major classifications of steels: carbon steel, alloy steel, high-strength low-alloy steel, stainless steel and tool steel.

Carbon steels are the most common, containing various amounts of carbon, produce everything from machines to bedsprings to bobby pins.

Alloy steels have definite amounts of vanadium, molybdenum, manganese, silicon and cooper. Alloy steels produce gears, carving knives and even roller skates.

Stainless steels have chromium, nickel amongst other alloy elements which sustains their color and reaction to rust. Stainless steel products include pipes, space capsules, surgical equipment to kitchen equipment.

Last but not least, tool steels have tungsten, molybdenum amongst other alloy elements. These elements create the strength and ability of the tool steel products, which include parts for manufacturing operations as well as machinery.

The varying amounts of carbon, amongst other elements in each of the types of steel create a variety in densities or specific gravities. (Specific gravity or relative density is the ratio of a material's density to that of water.)

Stainless steels are the most dense, coming in at 8000 kg/m3. Though the densities vary, the density of steel is about 7700 kg/m3. The density of steel are measured in g/cm3, kg/m3, kg/L and lb/f3, with kg/m3 being the more commonly used measurement.
 
Below list shows Density (g/cm3) with in bracket
1.Low Alloy & Alloy Steels (7.60)
2.Stainless Steels MIM-316L (7.80)
3.Stainless Steels 304 L (7.75)
4.Soft Magnetic Alloys MIM-430L (7.50)
5.Soft Magnetic Alloys MIM-Fe-50%Ni (7.70)
6.Controlled Expansion Alloy Kovar (F-15 Alloy) (8.00)

Henry Bessemer created the Bessemer process in 1856 to manufacture steel cheaply.
