AISI S5 Shock Resistant Tool steel
DESCRIPTION
An electric furnace, high quality shock resisting steel. Developed originally to meet the need for a shock-resisting steel which combines great ductility with high hardness.
ADVANTAGES
-
Maximum shock-resistance for hardness under Rockwell C-59
-
Good wear-resistance
-
Hardens in either oil or water

SILICON ……………………1.85 MOLYBDENUM ………0.50
VANADIUM ………………..0.25
HEAT TREATMENT
FORGING ………………………………..1850°F to 1950°F, stop at 1650°F and cool slowly
NORMALIZING ………………………...Do not normalize
ANNEALING ……………………………1450°F, furnace cool. Brinell 229
HARDENING ……………………………1625°F oil-quenched; 1550°F, water quench to 150°F
TEMPERING ……………………………...400°F to 650°F, Rockwell C-61-57
MACHINABILITY
Machines without great difficulty when annealed to a maximum of 229 Brinell. Has a rating of 65 as compared with a one percent carbon Tool steel which has a rating of 100.
TEMPERING RESULTS
Normal tempering procedure is to hold at temperature for at least 1 hour for each inch of greatest thickness. Tempering temperatures will normally be between 400 and 650F, depending on the service desired. The resulting Rockwell C hardness for oil-and water-quenching and tempering from 300 to 1300F by 100-degree intervals are as follows:
| Hardness Rockwell C | ||
| Tempering Temperatures °F |
Oil-quenched 1600°F |
Water-quenched 1600°F |
| 300 | 63 | 63 |
| 400 | 61 | 61 |
| 500 | 60.5 | 60 |
| 600 | 59 | 59 |
| 700 | 57.5 | 57.5 |
| 800 | 53 | 53.5 |
| 900 | 51 | 51 |
| 1000 | 49 | 48 |
| 1100 | 47 | 45 |
| 1200 | 40.50 | 40 |
| 1300 | 33.50 | 30 |
Results may be used as a guide in tempering tools to desired hardness. However, since ¾-in. diameter specimens were used in the test, tools of heavy section or mass may be several points lower in Rockwell hardness a given treatment.

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.
