Spring steel refers to steel, ordinarily of the high carbon or alloy type, utilized within the manufacture of springs. The steel is handled by cold drawing, cold rolling, or heat treating to deliver it the flexible properties and yield quality required in springs. Spring steel is frequently utilized since of its high yield qualities, resistance to deformation, and its capacity to return to its unique shape. Our spring steel and spring steel strips are accessible as heat-treatable annealed, which permits the shaping to happen earlier to the heat treatment, or heat treated, where the steel is already solidified, tempered, or sprung. Our stock of annealed spring steel can be effectively shaped, tempered, heat treated, blanked or formed.

Unique Properties Of Spring Steel

We carries annealed spring steel in three varieties, which are distinguished based on their carbon content:

  1. AISI 1050 has the lowest carbon content, making it easily formable. It also can be heat treated in order to increase hardness.
  2. AISI 1074 and 1075 have a medium carbon content that’s been spheroidized to increase its formability, and can be heat treated.

AISI 1095 has the highest carbon content of the spring steels we carry. It can be heat treated, and also has the highest elasticity and fatigue values.

Frequently Asked Questions

Most frequent questions and answers

What is a spring steel coil?

The term “spring steel” refers to a broad spectrum of steel used in the production of various goods, such as springs, saw blades, and swords. These steels typically have a very high yield strength and are low-alloy manganese, medium- or high-carbon steels.

What is spring steel used for?

It is a typical material used to create products including springs, washers, saw blades, lock picks, antennae, and scrapers. Additionally, it’s frequently used to make coil springs for vehicles, landing gear for light aircraft, and components for lawn mowers.

Is spring steel stronger than mild steel?

“Spring steel” is a catch-all phrase for steel that has undergone processing to obtain a very high yield strength, typically but not necessarily through cold working. Because of this, it will be able to resist “taking a set” when you load it heavily—or at least far more so than mild steel.

What distinguishes spring steel from stainless steel?

Stainless steel, a material for general-purpose spring wire that can be cold drawn, is heat and corrosion resistant, magnetic, and spring-tempered. Compared to alloy or plain steels, alloy steels with 10% or more chromium offer higher corrosion resistance. Rainfall and austenitic hardening are frequently used in springs.

What kind of steel is used in coil springs?

Steel that is high in carbon
The most often used form of steel for the production of coil springs is high carbon steel. Available in 1045 and 1095 alloys, it is robust, long-lasting, and affordable.
