60 minutes at temper temperature. Figure 2 (Strength vs. Tempering) This data generated in a laboratory shows the effect of tempering on strength for 1.25" and 2" wall tubing. Austenitized at 1625F (885C) and water quenched. Soak time of approximately 60 minutes at temper temperature.
Suggesting a high temper for a steel like 1045, thats like pearls on swine! temper at 450F. Don Hanson has it right get it hot put it in water, agitate, add a little soap and salt even if you want. I have made dozens of hammers and tooling from it it is probably my favorite steel, never had a problem with this method.
1045 has a low through hardening capability with sections up to around 60mm only generally recommended as suitable for through hardening and tempering. PMPA Designer's Guide: Heat Treatment When specifying heat treating or annealing on a drawing, it is preferable to note A standard chart is available which shows a correction factor.
1045 has a low through hardening capability with sections up to around 60mm only generally recommended as suitable for through hardening and tempering. It can however be successfully flame or induction hardened in the as rolled or normalised condition resulting in surface hardnesses of up to Rc 54 - Rc 60 depending upon quenching medium employed,
AISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot-rolled condition. AISI 1045 steel has a low through-hardening capability with only sections of around 60 mm in size being recommended as suitable for tempering and through-hardening.

I tempered mine by heating the drift and putting it in the eye till the colors ran to what I wanted, then quenched. The drift needed to be reheated several times so the tempering heat had a good long soak to do the job. Frosty Quote; Share this post , buy sm490b young's modulus Heat Treating 1045

MEDIUM TENSILE STEEL AISI 1045 AISI 1045 Medium Carbon, Medium Tensile Steel, supplied black as rolled, black as forged or normalised and bright drawn or smooth turned, offering good strength, toughness and wear resistance. Will through harden in sections up to 63mm with a tensile strength of 620 - 850 MPa. TYPICAL APPLICATIONS:
Tempering can further decrease the hardness, increasing the ductility to a point more like annealed steel. Tempering is often used on carbon steels, producing much the same results. The process, called "normalize and temper", is used frequently on steels such as 1045 carbon steel, or most other steels containing 0.35 to 0.55% carbon.
General characteristics of Carbon Steel 1045. C1045 is a medium carbon, medium tensile steel supplied as forged or normalized. This steel shows reasonable strength and toughness. C1045 will through harden to 2.5 (63mm) with a tensile strength of 66-120 Ksi (620-850 MPa) , buy sm490b young's modulus Tempering after normal hardening and oil or water quenching is , buy sm490b young's modulus

Atlas 1045 black round bar is supplied with max. dimensional tolerance on diameter of 1.5% (min. 0.4mm). Atlas 1045 cold drawn/turned round bar is supplied in tolerance h10 or h9. Atlas 1045 centreless ground round bar is supplied in tolerance h8 or better. Atlas 1045 square bar, hexagonal bar and flat bar are supplied in tolerance h11.
Lastly, a temper temperature of 700 F on an already substandard tap material (such as 1045)will be better described as "incomplete annealing" than much of a temper. I would venture a guess here, but I think the "improved plowshare steel" you speak of tempering at 700 F may barely be suitable as a plow point when treated as such.
Oil quenching--I have had good experience oil quenching 1045, even though 1045 is classified as water hardening steel. I used to heat a section of a part that was 1/4" thick with a torch, and once it was hot enough, tapped the part with a bar in my left hand, sliding the part down a chute to the quench oil bucket.

Tempering Temperatures All quenched parts require tempering to soften the martensite and reduce internal stresses caused by the quench. Desired hardness after tempering ranges from Rc 35 Rc 55 with lower hardness specified when improved machining is desired. The following chart may be used as a guideline for predicting final hardness.

incidental elements are at a minimum. Quenched-and-tempered properties are based on treating a .530 round for the hardening grades and a .565 round for the carburizing grades. These sizes are small enough to insure a thoroughly effective quench. Thus, the charts reflect typical values that may be expected of fully-hardened steels.
C1045 hot roll plate is a silicon killed medium carbon steel. In the as-rolled condition, higher carbon content imparts increased strength over low carbon steels, such as 1018. 1045 hot roll plate is often stress relieved, normalized, or annealed after burning shapes to size to allow for easier machining.
