Alloy G-30 (UNS N06030) is a Ni-Cr-Fe corrosion-resistant alloy with alloying additions of molibdenum, tungsten, copper and niobium. Generally resistant to oxidizing environments, it's extremely resistant to phosphoric acid (P2O5) and thus used widely in the production of agrichemical fertilizers. It can be seen as a low-carbon variant of alloy G, with improved weldability (it's less prone to heat-affected zome carbide precipitation and hot-cracking), and ductility.Used in phosphoric acid plants, sulphuric acid service, nitric acid service, pickling operations, petrochemical operations, fertilizer manufacture, pesticide manufacture, gold extraction and nuclear waste processing.
Threaded elbows (also known as threaded elbows) are pipe fittings that change the direction of the pipeline in the pipeline system. According to the angle, there are 45° and 90° elbows. In addition, according to the needs of the project, there are also other abnormal angle elbows such as 60°. The materials of threaded elbows include cast iron, stainless steel, alloy steel, wrought iron, carbon steel, non-ferrous metals and plastics.
