I. What is the exit line for small-cap stocks
Annealing wire is a metal wire that has undergone an annealing process, just like giving the metal a 'SPA' treatment. By heating to a specific temperature and then slowly cooling, internal stress is eliminated, making the wire softer and more malleable. This process is often used in situations where subsequent bending and stamping processing is required, such as the production of springs and precision parts.
Ii. Secrets of the Materials of 0.8 and 08 Retirement Wires
The meanings of the numbers: Both 0.8 and 08 indicate that the diameter of the wire is 0.8 millimeters, but the writing habits are different
Common materials: Mostly low-carbon steel or stainless steel. The former is low in cost and easy to process, while the latter has strong corrosion resistance
Performance features: After annealing, the hardness is approximately HV120-150, the tensile strength is 400-500 mpa, and the elongation can reach over 20%
Iii. Guidelines for Selecting Annealing Lines and Quenching Lines
Should annealing or quenching be chosen for No. 8 (about 4mm) wire? The key lies in the purpose:
Annealing line: Suitable for processing that requires plastic deformation, such as weaving and winding
Quenching line: It is used in scenarios that require high hardness, such as cutting tools
Mixed process: Some special wires are first annealed and then quenched for strengthening, taking into account both formability and final strength
