65mn spring steel strip is a kind of high carbon spring steel with good mechanical properties and high hardenability. It can be used to make various springs, such as coil springs, leaf springs, blade springs and disc springs. 65mn spring steel strip has high strength, elasticity and wear resistance, and can withstand high working stress and fatigue load. 65mn spring steel strip is widely used in machinery, automobile, railway, mining, construction and other industries.

     According to the chemical composition of 65mn spring steel strip, it contains about 0.62-0.70% carbon, 0.90-1.20% manganese, less than 0.25% silicon, less than 0.35% phosphorus, less than 0.25% sulfur and less than 0.25% nickel. The main alloying element is manganese, which improves the hardenability and toughness of the steel. However, 65mn spring steel strip also has some disadvantages, such as overheat sensitivity and temper brittleness. Therefore, it should be quenched and tempered properly to avoid cracks and reduce brittleness. 

      The specification of 65mn spring steel strip can vary according to different standards and applications. Generally, the thickness ranges from 0.03mm to 3mm, and the width ranges from 12.7mm to 1250mm. The surface of 65mn spring steel strip can be polished, blue, yellow or bright according to different requirements. The hardness of 65mn spring steel strip can be adjusted by heat treatment or cold rolling. The typical hardness after quenching and tempering is about HRC40-52.

 65mn spring steel strip is a high-quality material for making various kinds of springs. It has excellent performance and wide application range. However, it also requires careful processing and maintenance to ensure its durability and reliability.
