Hot spring in spring steel is an important material, spring steel is designed to manufacture all kinds of springs and elastic components or key performance requirements of the structural components similar.Hot spring 06Hot spring of spring steel material performance requirements:a, high elastic limit and yield ratio σe σs / σb, in order to ensure good elastic properties, which can not absorb large amounts of elastic plastic deformation;b, high fatigue limit, fatigue is one of the main failure mode of the spring, in addition to the fatigue properties of structural steel components of the outside, but mainly by the steel, metallurgical quality (such as non-metallic inclusions) and spring surface quality (such as decarbonization) effects;c, sufficient plasticity and toughness, in order to prevent the impact fracture;d, other properties, such as good heat treatment and plastic processing performance, under special conditions of heat or corrosion resistance requirements.Hot spring production process variedNow hot springs is still very broad range of applications, due to the lifting construction requirements, increase the difficulty of the job environment, and therefore part of the requirements for equipment and components are also very strict. Thermal springs belongs method of manufacturing a high temperature disc spring spring manufacturing technology in the field, the main component of the disc spring: 4Cr5MoSiV1 or 0Cr17Ni7Al. It consists of chromium, nickel, titanium, aluminum, tungsten, carbon, silicon, manganese, molybdenum, niobium, iron, copper material. Through the preparation of raw materials, the raw material into high-temperature vacuum furnace melting the solid, aging treatment, a nickel-based alloy material. Since many rare elements added, so it only has a high temperature resistance, corrosion resistance and many other advantages
