Technical instructions for the treatment of carbon

Carbon steel elbow is a common pipe connection, with flexible bending direction, wide Angle range, simple production process and so on. When using carbon steel head, in order to improve its service life and performance, a series of processing techniques are required. This paper will introduce the treatment technology of carbon steel elbow in detail, including heat treatment, anti-corrosion treatment and surface treatment.

First, heat treatment technology

Heat treatment is the process of heating and cooling carbon steel elbows with the aim of changing their microstructure and mechanical properties. Common heat treatment methods include annealing, normalizing, quenching and tempering.

1. Annealing treatment: the carbon steel elbow is heated to a certain temperature, and slowly cooled after holding for a period of time. Annealing can eliminate the internal stress, improve plasticity and toughness, and improve the impact toughness and plasticity of the elbow.

2. Normalizing treatment: heat the carbon steel elbow to the critical temperature, and cool it quickly after holding for a period of time. Normalizing can improve the hardness and strength of carbon steel elbow, which is suitable for occasions with high strength requirements.
