What are the properties of 65Mn steel?

65Mn  grade is a spring steel. This steel has excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), anti-elasticity reduction performance (ie, anti-elasticity reduction performance, also known as anti-relaxation performance), fatigue performance, hardenability Physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). In order to meet the above performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), and precise shape and size.
