will produce distortion during heat treatment. For this reason, thermal stresses during heating should be avoided. The fundamental rule for heating to hardening temperature is there-fore, that it should take place slowly, increasing just a few degrees per minute. In every heat treatmentHeat Treating Tool Steel - How To Choose The Right p20 with heat treatmentThrough hardening treatment gives uniform hardness throughout the entire work piece. Below are 4 of the most common steels used to build injection molds and their recommended treatments P20 Heat Treating Tool Steel .

As High Hardness Steel P20 Material is Typically Sold in The Pre-Hardened Condition. For Hardening, Heat Treatment is not Needed. After Machining and Intermittently During Pottery, The Steel must be Thermally Stress Relieved by Heating to 900ºF (482ºC). Equalizing and Holding for One Hour per inch (25.4mm) of Width.

Preheating Because P20 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.
Apr 25, 2013 · There are two major advantages to using P20 from a heat-treating perspective. The first is that heat treaters are familiar with the mate- rial and can draw on lots of experience in recommending a profile to suit a specific job. The other is that P20 can be commonly machined in the pre-hardened and tempered condition, then readily treated post-machining if necessary.Nitriding - Metlab Heat TreatingLarge gear for an industrial application nitrided to a 0.040" case depth. Gear measures 12' in diameter by 12' tall and weighs approximately 24,000 pounds. Gear hub, bore and web faces have been masked to prevent nitriding to allow for post heat treatment machining. Nitriding Facilities. NitridingP20 AISI P20 Tool Steel - Tool Steel Specification and p20 with heat treatmentAISI SAE P-20 Tool Steel. AISI SAE P-20 is a pre hardened high tensile tool steel which offers ready machineability in the hardened and tempered condition, therefore does not require further heat treatment.This eliminates the risks, cost, and waiting time of heat treatment thus avoiding the associated possibility of distortion or even cracking.

Forging of P20 Tool Steel. Slowly heat steel material, soak enough time for the steel to heated through. then start forging at about 1050°C. Below 930°C dont forging, pls reheating if necessary. After finished forging, cool in heat treatment furnace very slowly to room temperature.
P20 is a chrome-moly tool steel made specifically to fill the requirements for the machined cavities and forces used In zinc die casting and plastic molding. It Is delivered fully quenched and tempered to approximately Brinell 300. Other hardness P20heat treatment. P20 Is the standard mold steel for machine-cut plastic molds and zinc die casting dies. P20 Is usually supplied in the prehardened condition, about 300 Brinell, for injection molds and zinc die casting dies. While in the prehardened condition, P20 can be nitrided for greater wear resistanoe.P20S Tool Steel - West Yorkshire Steel - ISO 9001 ApprovedOther considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities.
