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.

A threaded elbow (also known as a buckle elbow) is a pipe fitting that changes the direction of a pipe in a piping system. According to the Angle, there are 45° and 90°, and other abnormal Angle elbows such as 60° are also included according to the engineering needs. The materials of screw elbow are cast iron, stainless steel, alloy steel, calcined cast iron, carbon steel, non-ferrous metals and plastics. The threaded elbow is composed of a screw, a bending part, etc., which is characterized by a threaded groove on the screw. In the pipeline system, the threaded elbow is a pipe fitting that changes the direction of the pipeline.
