High carbon steel (0.90-1.20% carbon), cold-rolled and heat treated to high hardness before coiling, results in very high tensile strength with an elastic limit about 90% of the tensile strength and hardness of 48-52 HRC. Clock-spring steel wire is used for brush holders, clock and motor springs and other flat springs for high stresses.
AISI SAE 1095 carbon steel can be made into steel billets, steel powder, which can be used as tool steel, blade steel, spring steel. 1095 high carbon steel uses mainly include chef knife, kitchen knife, pocket knife, Bowie knife, hunting knife, doctor blade, wear parts, various springs, ploughshares, and brake discs.
Place the steel into a heat treat oven or forge and raise the temperature to between 1,550 degrees Fahrenheit and 1,650 degrees Fahrenheit. Allow the steel to remain in the oven for a "soak" time of at least 30 minutes. Allow more soak time for more massive pieces of steel.
How to Heat Treat Spring Steel Definition of Heat Treating Springs: Wire springs are placed in an oven or furnace for a certain time and temperature to relieve stress as well as to temper the spring wire to give the spring its elasticity and memory .
This specification deals with the general requirements for round carbon spring steel wire coils intended for the manufacture of mechanical springs and wire forms that are heat treated after fabrication. Heat treatment processes include austenitizing, quenching and tempering.
Assuming a plain high carbon steel like 1095 you would heat until non-magnetic and then 50F more to 1480F. Then quench in warm water. Temper immediately (as soon as possible) at a minimum of 450F for up to 2 hours to obtain Rockwell 57-58.
The only heat treatments you can do on Mild Steel is anneal, normalize or stress relieve you cannot harden and temper it which is probably what your thinking of to get your spring. You need a spring steel for your application so you can improve the mechanical properties by heat treatment.
The purpose of heat treating is to bring steel to a hardened state. The correct hardness depends on the application of the steel being treated. Knives need to be hard enough to hold an sharp edge through continuous mechanical abrasion, yet be soft (flexible) enough to stand up to forceful use without breaking.
Spring Steel. Each type of spring steel, such as our blue tempered and polished strip, 4130 heat treatable strip, and 1095 carbon spring steel, conforms completely to its AISI and ASTM Standards of excellence. Other spring materials that we carry include 301 stainless strip, both the tempered and annealed 410 stainless strip and many more, heat treatment high carbon spring steel
ASTM SAE AISI 1045 steel is one of the commonly used medium carbon steels with an average carbon content of 0.45%, medium tensile properties, good strength, toughness and wear resistance. It can be treated by annealing, flame treatment or induction hardening.
Carbon steels which can successfully undergo heat-treatment have a carbon content in the range of 0.301.70% by weight. Trace impurities of various other elements can have a significant effect on the quality of the resulting steel.
Considered a high-carbon alloy steel. As quenched hardness of 58 to 63 HRC. Used for a variety of spring applications, notably flat springs. Often uses Austempering as a method of heat-treating. Forging max heat 2200 degrees F. Do not forge below 1600 degrees F. Normalizing - heat to 1600 F and cool in air.
For high carbon steel, it needs to be heated up to 200C (400F), held at this temperature for an hour and then left to cool back down to room temperature. This is then repeated another two times for a total of three heat cycles.
When high carbon spring steels are used for manufacturing, it is a standard requirement that the product is heat treated and quenched to a hardness level that allows the product to flex without deforming. Heat treating and oil quenching are commonly used for the hardening process, but an Austemper heat treating process is typically the best practice for eliminating heat treat deformation.
Cryo Treatment: Cryotreatment, soaking steel after hardening but before tempering at temperaturesat least minus -90F (dry ice range) to minus -290F (liquid nitrogen range) foreight hours.
It added carbon creates a carbon rich martensite with plenty of free carbide for good abrasion resistance. The downside of the extra carbon is that it requires more care in the heat treatment, avoid lamellar annealing and overheating. Recommended Working Sequence For 1095 Forging: heat to 2100F (1150C).

Double high temperature tempering preceding quenching increases the resistance to bending and the impact strength of case hardened samples of 18Kh2N4VA steel. 5. Treatment at very low temperature increases the hardness and the wear resistance but decreases the impact strength and in most cases decreases the resistance to bending of steels with , heat treatment high carbon spring steel
Heat Treatment Processes. Hardening. Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
Out of all high carbon spring steels, AISI 1074/1075 is by far the most common and affordable. AISI 1074/1075 exhibits excellent spring properties, making it the number one choice for most of the custom flat springs, custom sheet metal stampings, and custom metal clips we produce for our customers.
1074 Spring Steels are tempered spring steels that looks and acts much like blue tempered steels with heat treatment ranging from 1400-1650 degrees F. Go to Navigation Go to Content Were Here To Help, Give Us A Call | 800-323-0740
in talking about the 10XX's, more carbon is better, because it's a simple steel, as you say,, proper methods for heat treating is Key, if not with more carbon it should make it more forgiving HT wise for those that don't do a good job in the HT .
The machinability rate of AISI 1075 carbon steel is 50. Forming. AISI 1075 carbon steel can be formed using conventional techniques. Welding. AISI 1075 carbon steel can be welded using all welding methods. It is pre-heated at 260 to 315C (500 to 600F) and post-heated at 649 to 788C (1200 to 1450F) to prevent cracking. Heat Treatment , heat treatment high carbon spring steel
Very few metals react to heat treatment in the same manner, or to the same extent, that carbon steel does, and carbon-steel heat-treating behavior can vary radically depending on alloying elements. Steel can be softened to a very malleable state through annealing, or it can be hardened to a state nearly as rigid and brittle as glass by quenching.
