Main causes of subsurface bubble formation in Q345C carbon steel material

The main applications of normalizing are as follows:① For low carbon steel, Q345C carbon steel material. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.

This kind of steel Q345C carbon steel material is generally used in the quenched and tempered state, and can also be used in the normalized state, and is suitable for manufacturing parts that work under higher stress and wear conditions. When the diameter of the workpiece is less than 60mm, the performance of 45mn2 structural steel is equivalent to that of 40Cr steel. 45mn2 structural steel is used in parts under higher stress and wear conditions, such as universal joint shafts, axles, connecting rod covers, friction discs, worms, gears, gear shafts and other quenched and tempered or normalized parts.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for Q345C carbon steel material various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several Q345C carbon steel material after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
