CHARACTERISTICS
Although less alloyed than the conventional High Carbon High Chromium qualities, this steel has similar non-distorting properties and is easier to machine. It still maintains good resistance to abraision and combines this with excellent toughness.
Colour Code: DARK BLUE.

TYPICAL APPLICATIONS

•	Thread rolling dies	•	Shear blades
•	Knurling tools	•	Cold stamping dies
•	Gauges	•	Coining tools
•	Engraving rollers	•	Heading die inserts
•	Impact extrusion punches and dies	•	Swaging rolls and dies.
•	Heavy duty press and blanking tools

HEAT TREATMENT graph

FORGING
Commence at 1000^oC. Re-heat as necessary to avoid working below 900^oC.

ANNEALING
Soak thoroughly at 840/850^oC. Cool in furnace not faster than 20^oC per hour.

STRESS RELIEVING
Heat uniformly to 650^oC max. Allow to equalise and remove from furnace. Cool in still air to room temperature.

HARDENING & TEMPERING
Thoroughly warm Tools or Components before charging

HEATING & SOAKING
(a) Salt Bath Procedure
Charge Tools into Pre-heater chamber at 300/400^oC and soak thoroughly up to 1 hour per inch of ruling section. Remove to Neutral Salt Bath operating at 700/750^oC and maintain at this temperature for 15 minutes per inch of ruling section. Raise heat of Salt Bath to 950/970^oC and allow sufficient time to equalise but do not soak for more than a few minutes.

(b) Open Furnace Procedure
Charge Tools into muffle furnace working at 300/400^oC and soak thoroughly, preferably 1 hour per inch of ruling section. Raise heat as rapidly as possible to 950/970^oC and allow sufficient time to equalise but do not soak for more than a few minutes.

QUENCHING
(1) Quench in oil - ALTERNATIVELY
(2) Quench in Martempering Salt Bath at 540^oC. Allow to equalise and cool in still air.
Tools should be tempered immediately whilst still hand warm.

TEMPERING
Temper to your requirements according to the tempering graph - soaking at temperature for 1 hour per inch ruling section or 2 hours whichever is longer. A second temper is recommended as being beneficial. This steel should respod to hardening by the Vacuum furnace, gas quench process.
