A709 Grade 50W steel is a standard specification for structural steel in bridges with weathering capabilities. With a corrosion index of 6.0 or higher, ASTM A709-50W has substantially better atmosphere corrosion resistance than carbon steels even with the addition of copper.
A36 steel plate is a popular steel plate grade used for a variety of structural applications, including buildings. Available for heavy steel plate applications in up to 18 thickness.

Engineering Bits & Bytes Days are STEM curriculum enrichment experiences held on the NC State Centennial campus for students in elementary, middle and high school grades 3 12. These are half-day events held once a semester and include age- and grade-appropriate hands-on engineering activities and often a tour of Hunt Library. Keeping tabs on current ASTM specifications ARE YOU The preferred material specification for round HSS is ASTM A500 Grade C (F y = 46 ksi, Fu = 62 ksi). Note that a new standard, ASTM A1085 (see sidebar New (and Recently New) Things), seeks to replace it. The availability and cost effective-ness of round HSS in grades other than ASTM A500 Grade C should be confirmed prior to specification.
A batch size of about 40 kg is recommended for a production-scale mill (about 50 cm diameter and 150 cm length). The compound recipe contains 100 phr E-60C precompound, 30 phr MT black, 6 phr calcium hydroxide, and 3 phr magnesium oxide. The clean mill is cooled to about 25°C Science HowStuffWorksScience explains and demystifies the world through the objective of gathering and analyzing data.
