The quality of springs hinges heavily on decarburization control.
Do you know why springs that endure constant compression, vibration and bending day in and day out rarely break? Spring steel is mainly alloyed with silicon, manganese and chromium, delivering far superior performance compared to ordinary steel.
Since it bears long-term impact, vibration and cyclic alternating tensile force, it must feature excellent elasticity, fatigue resistance and high toughness.
Springs specially used for precision instruments and electrical appliances also need additional high temperature resistance and corrosion resistance.
Steel mills mostly supply such materials in the form of wire rods, steel wires and flat steel, which are then processed into various coil springs and special-shaped flat springs.
This type of steel has extremely strict requirements on surface decarburization control; even slight decarburization will impair its elasticity and make it prone to fatigue fracture.
弹簧好不好，脱碳管控很重要
你知道天天反复受压、震动弯折的弹簧，为什么不容易断吗？ 弹簧钢核心含有硅、锰、铬合金元素，性能远超普通钢材。 长期承受冲击、震动、循环交变拉力，所以必须弹性好、抗疲劳、韧性强。 精密仪表、电器专用弹簧，还要额外耐高温、耐腐蚀。 钢厂出厂多为盘条、钢丝、扁钢，加工成各种螺旋弹簧、异形扁弹簧。 这种钢材对表面脱碳管控极严，稍有脱碳就会影响弹性、容易疲劳断裂。#模具钢 #模具 #steel
