NXF ASTM B574 ASTM B619 Alloy C-4 / UNS N06455/ W.Nr.2.4610 DN6-1200 Pipe Fittings Hex Head Plug
Product Description
Alloy C-4 is an austenitic nickel-molybdenum-chromium alloy with a low carbon, silicon, and iron content. This alloy has a significantly lower tendency to form precipitation in the temperature range between 650 and 1,040 °C(1,202 - 1,904 °F), improving its resistance to inter-crystalline corrosion. When machined perfectly, no knife line attack occurs in the heat-affected zones of awelding edge. Alloy C-4 is characterized by: Very good resistance in a broad field of corrosive media, in particular under strongly oxidizing conditions. Excellent resistance to pitting, crevice and stress corrosion.Hex head plug internal and external thread joint used to connect the screw head and matching handle supporting tools, hexagonal head internal and external thread joint is also called Bushing (Bushing), generally by the hexagonal bar cutting and forging processing, the use of thread types are many, it is connected to two sections of diameter is not the same as the internal and external thread fittings, in the pipeline connection has an irreplaceable role.
