INTRODUCTION
Spring steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic components. According to the performance requirements and service conditions, it can be divided into ordinary alloy spring steel and special alloy spring steel.
Spring steel has excellent comprehensive properties, excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), and accurate shape and size. The outstanding advantage of Alloy 5155 is that it has good hardenability. In addition, it has good heat-working performance, comprehensive mechanical properties and anti-decarburization performance as well.
APPLICATIONS
Usually used to make all kinds of important springs with large cross-section, such as large leaf springs and coil springs of automobiles and locomotives.
