Blue tempered spring steel can be permanently bent by exceeding the yield strength. Bending causes tensile stress on the outside of the bend. You can reach the tensile strength of the steel if you bend with too small an inside radius. In other words, the part will crack or break. So the key is to bend with the largest possible inside radius.
Spring steel is a name given to a wide range of steels used in the manufacture of springs, prominently in automotive and industrial suspension applications. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength.
Yield strength is an important parameter which we are capable of calibrating to a precise degree thanks to our experience combining chemical composition, cold rolling and heat treatment. When it comes to spring steels, we are able to manufacture various high-performance materials with yield strengths (Rp0.2) of up to 2,800 MPa (406 ksi).
Engineering Materials. Spring Steel Review. Spring steel. is generally classified as a low alloy, medium carbon steel or high carbon steel with a very high yield strength.. This allows the shaped materialto return to their original shape despite significant bending or twisting.

Forming and Tempering spring steel 2005. Hi, I work Clydesdales Horses. Many pieces of old equipment come with broken Spring tines, as these are not available today I wish to have a go at making them myself. I have a forge and play fairly successfully but have no knowledge of spring steel or how to temper it. Hoping you can help. Regards , harden and temper yield strength spring steel
Spring steel in the hardened and tempered condition is used mainly for the production of flat springs, blades and saws, and is it very difficult to form. If you require spring steel for forming before heat treatment, we stock a range of steels in annealed condition as well.
The austenitic stainless spring steel strips like 301 and 302 are temper rolled for light springs versus the martensitic spring steels, such as the 420 stainless strips, that are heat treatable for high hardness and toughness and are typically used for hardened tools.
Tempering is used to precisely balance the mechanical properties of the metal, such as shear strength, yield strength, hardness, ductility and tensile strength, to achieve any number of a combination of properties, making the steel useful for a wide variety of applications. Tools such as hammers and wrenches require good resistance to abrasion , harden and temper yield strength spring steel
In its full hard condition, type 301 has a tensile strength of 185,000 PSI minimum, and a minimum yield strength of 140,000 PSI. The combination of hardness and toughness make it ideal for springs. 301 Full Hard Tempered Stainless Steel Sheet & Coil - AMS 5519
The steel is very hard, but very brittle. By tempering steel, the atoms are allowed to rearrange into a more stable position. The hardness of steel is sacrificed for ductility (the materials ability to stretch or deform). The end result is a material with increased strength and toughness.
Spring steels are known for their high yield strength, which allows objects made of spring steel to return to their original shape after significant bending or twisting. Mead Metals Inc. offers tempered spring steel in multiple grades, sizes, and quantities to meet your needs. Typical Yield for Minimum Lot Charge: 10-12# Sourced From: India
Type 410 stainless steel in its cold rolled, hardened and tempered condition is used in countless applications similar to Cold Rolled High Carbon Spring Steel Strip but with the advantages inherent in being stainless and at moderate cost. Its formability is good for its yield strength and hardness range.
in improved fatigue strength. Hardening Austenitizing followed by quenching and tempering is used on a variety of high carbon steels and high carbon alloy steels to develop higher hardness (Fig. 3). The spring steel is heated above the materials upper critical temperature (Ac3) so that the crystal structure will convert to austenite (-iron).
Specializing in long production runs, Blue Blade Steel is one of the few hardening and tempering mills in the world able to provide you with the highest quality, customized high carbon pre-tempered spring steel that we harden and temper to strip steel tolerances! Always here to help you, our engineering and metallurgical team offers , harden and temper yield strength spring steel

Type 302 stainless steel wire is a general purpose stainless alloy typically composed of 18% chromium and 8% nickel. It is the most widely used stainless spring wire because of its high corrosion resistance properties and good tensile strength.
O1 Tool Steel. O1 Tool Steel is the original oil-hardening, non-shrinking tool steel that can be hardened to the Rockwell C 65 range from a low austenitizing temperature. O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance.
AISI 1095 carbon steel can be hardened at 899C (1650F). It is then quenched in oil followed by tempering. The cutting edge of cutting tools can be hardened by heating and quenching in order to maintain the toughness of the steel. Forging. AISI 1095 carbon steel can be forged at 955 to 1177C (1750 to 2150F).
Maintaining the superior properties of 188 stainless, SUS631 is the most common precipitation hardening stainless steel that can be hardened through heat treatment. It can be subjected to a variety of heat treatment processes to suit working and applications from the softest solution heat treatment to a hard full-hardened finish.
Hardening and tempering spring steel,spring steel heat treatment Heat treatment-Hardening and tempering process can improve the steel hardness and toughness. Forever is China professional , harden and temper yield strength spring steel
A large field of application for carbon steel is helical springs. The wire is first hardened by patenting and then drawn to the required strength. Thin section carbon-steel springs can be quenched and tempered too. The hardness of spring should match its dimensions. In principles, smaller the dimensions of the spring, the higher are the hardness.
HIGH TENSILE STEEL AISI 4140 AISI 4140 Chrome - Moly High Tensile Steel, generally supplied hardened and tempered to Condition T in sections up to 100mm, with a tensile strength of 850 1000 MPa and aiming for this strength range in larger sections. It offers a very good balance of strength, toughness and wear-resistance.

General Motors use 5160 in their leaf and coil springs this is a chromium steel with .6% carbon and works in heavy applications but is tough to forge when working on a reduced scale. The process of making a spring consists of: Forging, Filing, Polishing, Heat-treatment in the form of hardening and tempering, and a final polishing prior to fitting.
The difference between annealing and tempering comes down to how it is treated. Annealing involves heating steel to a specified temperature and then cooling at a very slow and controlled rate, whereas tempering involves heating the metal to a precise temperature below the critical point, and is often done in air, vacuum or inert atmospheres.
