  2. ASTM A500 - Wikipedia

    en.wikipedia.org/wiki/ASTM_A500

    ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly specified in the US for hollow structural sections, but the more stringent CSA G40.21 is preferred in Canada.

    A hypoeutectoid carbon steel (carbon composition smaller than the eutectoid one) is heated to approximately 30 to 50 °C (54 to 90 °F) above the austenictic temperature (A 3), whereas a hypereutectoid steel is heated to a temperature above the eutectoid one (A 1) for a certain number of hours; this ensures all the ferrite transforms into ...

    en.wikipedia.org/wiki/Area_density

    Fabric "weight" is often specified as mass per unit area, grams per square meter (gsm) or ounces per square yard. It is also sometimes specified in ounces per yard in a standard width for the particular cloth. One gram per square meter equals 0.0295 ounces per square yard; one ounce per square yard equals 33.9 grams per square meter.

  9. Steel - Wikipedia

    The carbon content of steel is between 0.02% and 2.14% by weight for plain carbon steel (iron-carbon alloys). Too little carbon content leaves (pure) iron quite soft, ductile, and weak. Carbon contents higher than those of steel make a brittle alloy commonly called pig iron.
