We also call ASTM A335 pipe as ASME SA335 Chrome-Moly pipe, it is a type of seamless pipe could be used in high temperature environments of 540 – 750 °C. While Molybdenum increases the overall strength, resistance, elasticity, hardenability and overall quality, moly ensures that the material is more resistant to softening, restrains the growth of grains and lessens the chances of embrittlement.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the 20mm thickness 14Cr1MoR steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between 20mm thickness 14Cr1MoR steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. 20mm thickness 14Cr1MoR steel, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
After setting, the CNC system set the cutting head to move at the same time the laser also began to move, stop at the 20mm thickness 14Cr1MoR steel same time the laser also stopped, so that there will be a beam on the wood from wide to narrow, and from narrow to wide burning traces of the laser beam. The narrowest trace is taken as the focus position, and the distance between the board and the lens is the actual focus position of the laser beam.
