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.

 

ASTM 9260 has high strength, good elasticity and good performance of temper resistance. It is easy to decarburize and graphitize, and the hardenability is not high. It is the main kind of spring steel, and widely used to manufacture all kinds of springs, such as leaf springs, coil springs of automobiles, locomotives, and tractors; cylinder safety valve springs, and some important springs operating under high stress, which have serious wear and tear.

 

APPLICATIONS

 

Alloy Steel 9260 is used in a number of different products and industries including:

  • Airplanes
  • Military weaponry
  • Rail transportation
  • Bridges
  • Machine tools
  • Knives and swords

PROCESSING

 

FORGING


A recommendation for general applications is 1925 – 1560ºF (1050-850ºC) and for springs 1650 – 1560ºF (900 – 850ºC.) Parts should be slow cooled after forging or transferred to an equalization treatment.

 

HEAT TREATMENT


Annealing: To produce a structure of coarse to fine spheroidite, parts should be austenitized at 1400ºF (760ºC) and cooled to 1300ºF (705º) at a rate of 10ºF/hr., or alternately cooled to 1225ºF (660ºC) and held for 10 hours as an iso-anneal.

 

Normalizing: 1650ºF (900ºC) and air cool. This will be an important treatment for this grade.

 

Hardening: Austenitize at 1525-1580ºF (830-860ºC) and water quench.

 

Tempering: 880-970ºF (470-520ºC)

 

Machinability: Parts could be machined following a spheroidize anneal

 

Weldability: The grade would not normally be welded.
