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.
90 degree socket welding elbow, hydraulic elbow is mainly made of forged steel material, the use of numerical control manufacturing process, processed into a high pressure joint applied in hydraulic pipe, because the application of high pressure, so also called high pressure pipe, hydraulic pipe. Socket welding elbow, 90 degree welding elbow, hydraulic elbow in chemical industry, mechanical and electrical, machinery manufacturing, shipbuilding, electric power, aerospace, automotive, petrochemical, hydraulic, pneumatic, textile, chemical fiber and other industries are widely used.
