In the Terai region, the southern parts of Nepal, the customary units are those used elsewhere in South Asia: 1 katha = 20 dhur; 1 bigha = 20 katha; Hilly and mountainous regions. A different system is used in hilly regions: 1 paisa = 4 dam (daam) 1 ana (aana) = 4 paisa [2] 1 ropani = 16 ana; Conversions 1 ropani = 74 feet × 74 feet; 1 bigha ...
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: no minimum content is specified or required for chromium , cobalt , molybdenum , nickel , niobium , titanium , tungsten , vanadium , zirconium , or any other element to ...
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
A572 steel has five different grades: 42, 50, 55, ... A572 Steel Chemical Composition, ... A572 Grade Carbon Manganese Phosphorus Sulfur Silicon Grade 42: 0.21%: 1.35%:
In 2008, 2009, 2015 and 2016 output fell in the majority of steel-producing countries as a result of the global recession. In 2010 and 2017, it started to rise again. Crude steel production contracted in all regions in 2019 except in Asia and the Middle East. India is the 2nd leading producer of iron and steel industries. [citation needed]
4. Materials and Manufacture of ASTM A53 Pipes 4.1 The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric-furnace, or basic-oxygen. 4.2 If steels of different grades are sequentially strand cast, identification of the resultant transition material is required.
Nepal Bureau of Standards & Metrology (NBSM) is a department under the Ministry of Industry, Nepal. [1] The department was established in 1976 based on the Industrial policy (1974) with an aim to regulate and improve the quality of industrial production. The initial name of the department was Nepal Institute of Standards (NIS).
ASTM A500 defines four grades of carbon steel based primarily on material strength. [1] This is a standard set by the standards organization ASTM International , a voluntary standards development organization that sets technical standards for materials, products, systems, and services.
