Alloy Steel 5160H, also known as AISI 5160H or SAE 5160, it is a high carbon chromium spring steel. 5160 is very common alloy and has been used in spring manufacturing for more than 100 years. 5160H is typically utilized in spring applications where larger material diameters are required. Its most common use is in material diameters greater than 0.625” (15.88 mm), although the material can be obtained in sizes as small as 0.375” (9.5 mm).

Applications of AISI 5160 Carbon Steel

Because of its availability and cost-effectiveness, AISI 5160H steel is utilized for a very large variety of applications. AISI 5160H steel is most commonly used for springs in railroad and automotive suspensions because of its strength and ductility and fatigue properties.
Industries using springs manufactured from AISI 5160 steel include:
1.Agriculture
2.Automotive
3.Mining
4.Oil & Gas
5.Power Plants
6.Railroad
7.Transportation Equipment
Coiling Technologies Inc. uses AISI 5160 steel to make different types of springs used in a wide range of industrial applications. The high tensile strength of AISI 5160 is often implemented in applications with smaller cross-sections under significant stress.
