Some of the important characteristics of materials are : strength, durability, flexibility, weight, resistance to heat and corrosion, ability to cast, welded or hardened, machinability, electrical conductivity, etc. [3] In contemporary design, sustainability is a key consideration in material selection.

ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.
Abrasion resistant steel is a high-carbon alloy steel that is produced to resist wear and stress. There are several grades of abrasion resistant steel, including ...
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.
DuPont made public in 1938 that their company had invented nylon. [1] This new invention was the first synthetic fiber, fabrics that are commonly used in textiles today. [2] In 1939, DuPont began marketing nylon monofilament fishing lines; however, braided Dacron lines remained the most used and popular fishing line for the next two decades, as early monofilament line was very stiff or "wiry ...

The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
Allowable Strength Design and Allowable Stress Design (ASD) are terms used by the American Institute of Steel Construction (AISC) in the 14th Edition of the Manual of Steel Construction. [ 1 ] [ 2 ]
