We know that in industrial production, copper screws need to be heat treated. So, how do you know how to heat copper screws? This is also a skill we need to master. Next, let’s take a look at the specific answer to this question together. 1. Screws We often use a variety of materials and types of screws in our lives. 2. What are the common materials of copper screws? a.Low Carbon Steel: Carbon steel Carbon steel is divided into low carbon steel, medium carbon steel, high carbon steel and alloy steel. b. SS-304: Stainless Steel 304 and 316 belong to stainless steel c. SS-302: Stainless Steel 302: Good structural toughness d. Aluminum 5052: Aluminum alloy 5052 d. Brass: Brass e. Bronze: Bronze f . UNS C11000 Copper: Antimony Copper Copper Screw Heat Treatment 3. How to operate copper screw heat treatment? Kehua summed it up for everyone as follows. 1. Spheroidizing (softening) annealing countersunk head screws 2. Peeling and descaling cold heading steel wire rods to remove iron oxide plates The drawing process has two purposes, one is to change the size of the raw material; the other is to obtain the basic mechanical properties of the fastener through deformation and strengthening 4. Cold forging Usually, the forming of the bolt head adopts cold heading plastic processing, which is the same as cutting processing. Compared with 5. Thread processing bolt threads are generally cold processed, so that the thread blank within a certain diameter range passes through the rubbing (rolling) wire plate (die), and the thread is formed by the pressure of the wire plate (rolling die) 6. Heat treatment of high-strength fasteners According to technical requirements, quenching and tempering treatment should be carried out. The purpose of heat treatment and tempering is to improve the comprehensive mechanical properties of fasteners to meet the specified tensile strength value and yield ratio of the product. The operation method of copper screw heat treatment is as described above. After reading it, have you added another skill? I hope the above content can help you better understand the heat treatment process.
