DESCRIPTION
A special analysis of Alloy steel which is heat treated by oil-quenching and tempering to develop a balance of mechanical properties. Has every requisite for brake die service-high wear-resistance, adequate toughness, high resistance to impact, and good machinability. In addition, the bars are stress-relieved before the final gag straightening, to insure a minimum of residual stresses.

CARBON ……0.51 MANGANES ………0.87
CHROMIUM …0.95 MOLYBDENUM ……0.20
ADVANTAGES
-
Heat treated, ready to use, needs no further hardening
-
Heat treated to the right hardness for maximum wear and toughness
-
Machines easily without warping-due to strain-relief treatment
-
Machines to a smooth surface without grinding
-
Hardened to between 248-293 Brinell – the correct hardness for most uses
-
High carbon content insures greater resistance to wear
-
Small areas can be flame hardened for better wear.
DISTORTIONAL PROPERTIES
As free from residual stresses as possible due to the method of heat treating. Machining an equal amount evenly from each side of the brake die will result in minimum deformation and warping.
COMPRESSIVE STRENGTH
To obtain values for this property, specimens were taken from large and small sections, machined oversize, heat treated and finished by grinding to 0.505 in. diameter x 0.750 in. long. The specimens were checked for hardness and were then compressed between hardened steel plates. the specimens tested showed a hardness of 269 Brinell and indicated that both small and large sections developed compressive strength in excess of 100,000 psi, adequate compressive strength to meet the maximum demand of heavy duty brake-die service.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
