60Si2Mn 0.5mm Spring Steel Sheet For Leaf Springs
60Si2Mn 0.5mm Spring Steel Sheet For Leaf Springs
Feature
-
Spring steel sheet refers to the steel that uses the elasticity in quenching and tempering state, and is specially used to make springs and elastic elements. By using the physical characteristics of materials, it can store and release energy through certain conversion methods, thus alleviating mechanical vibration and impact.
1). Material: 65Mn , 55Si2MnB, 60Si2Mn, 60Si2CrA, 55CrMnA , 60CrMnMoA , as per customer’s requirement
2). Packing: standard sea-worthy packing
3). Surface treatment: punched, welded, painted or as per customer’s requirement
4). Size: according to customer’s requirement
According to the chemical composition classification
According to GB/T 13304 standard, steel spring sheet is divided into non-alloy spring steel (carbon spring steel) and alloy spring steel according to its chemical composition.
①Carbon spring steel
②Alloy spring steel
In addition, some brands are selected as spring steels from other steels, such as high-quality carbon structural steel, carbon tool steel, high-speed tool steel and stainless steel.
Spring steel sheet has excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), elastic loss resistance (that is, elastic loss resistance, also known as relaxation resistance), fatigue performance, harden-ability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.).
In order to meet the above performance requirements, 0.5mm spring steel sheet also has excellent metallurgical quality (high purity and uniformity), good surface quality (strictly control surface defects and decarburization) and accurate shape and size.
60Si2Mn Spring steel sheet is used to manufacture medium and small section leaf springs, such as front and rear auxiliary leaf springs on automobiles; Manufacturing automobiles, tractors and other industries to manufacture leaf springs that work under large load and stress conditions.
For example, 55Si2MnB is a steel grade developed by China, and its harden-ability, comprehensive mechanical properties and fatigue properties are better than those of 60Si2Mn steel. It is mainly used to manufacture leaf springs of medium and small cars, and its application effect is good. It can also be used to make other leaf springs with medium cross-section size.
