AISI P20 Mold Tool Steel Thermal Properties

Equal grade for P20 and 1.2311

Heat treatment:

Stress Relieving

Preheating: Because mold steel P20 steel plate is sold in a pre-hardened condition, hardening heat treatment is not necessary. After machining and intermittently during service, the steel must be thermally stress relieved by heating to 900ºF (482ºC), equalizing and holding for one hour per inch (25.4mm) of thickness, and cooling in air to ambient temperature.

In those rare circumstances where the AISI steel P20 must be re-hardened, the steel must first be annealed prior to hardening.

Hardening

Critical Temperature: Ac1: 1405ºF (763ºC)

Preheating of P20 metal: Heat at a rate not exceeding 400ºF per hour (222ºC per hour) to 1150-1250ºF (621-677ºC) and equalize.

Austenitizing (High Heat)

Heat rapidly from the preheat to 1550ºF (843°C). Soak for 30 minutes for first inch (25.4mm) of thickness, plus 15 minutes for each additional inch (25.4mm).

Quenching

Pressurized gas, or interrupted oil to 150-125ºF (66-51ºC).

For oil, quench until black, at about 900°F (482°C), then cool in still air to 150-125°F (66-51°C).

Tempering

P20 tool steels are tempered at 482-593°C (900 to 1100°F) for a Rockwell C hardness of 37 to 28.

Annealing

Annealing for AISI P20 tool steels takes place at 760-788°C (1400 to 1450°F) and then the steels are cooled slowly in the furnace at a temperature less than 4°C (40°F) per hour.

.Material Production technical Process

6.Additional service- the manufacturing company also provides some additional services like tempered, quenching, annealing, coating, sandblasting, and painting.

7.Testing Detail- After the manufacturing process, this grade of steel plate is strictly sent to various quality measurement tests in order to confirm the end product quality. Following tests are performed such as ultrasonic examination, Impact test, HIC test, simulated post weld heat treatment(PWHT), third party inspection such as SGS test etc.

8.Packing detail- it is last but necessary part of manufacturing, as the product is shipped worldwide, so proper care is necessary in order to avoid any of damage during the transit. When product qualifies all above mention test then it is sent to packing. Packaging includes seaworthy packing or as per the buyer demand. Packing also includes batch no and heat number so that it can be tracked.
