4130 and 4140 Heat Treatments - Industrial Heating

Jun 08, 2011 · For 4140 steel, the recommended heat treatment [1] consists of heating to austenitizing temperature, typically 1570°F (855°C), followed by oil quenching. Tempering (reheating after quenching) will achieve the desired hardness range. From available data for an oil quenched, ½-inch-diameter round part, you will need to temper at (approximately 4130 and 4140 Heat Treatments - Industrial HeatingJun 08, 2011 · For 4140 steel, the recommended heat treatment [1] consists of heating to austenitizing temperature, typically 1570°F (855°C), followed by oil quenching.

Holes and threads in tool steel vs. heat treatment

Oct 10, 2012 · We heat treat an average of 25 pcs per week of all variety of tool steel (usually vacuum heat treated). The simple answer is there is no gaurantee. Small parts (1sq in) very little change (.0001 -.0002) . The larger the part and the more machining on it, the more distortion. Holes and threads in tool steel vs. heat treatmentOct 10, 2012 · We heat treat an average of 25 pcs per week of all variety of tool steel (usually vacuum heat treated). The simple answer is there is no gaurantee. Small parts (1sq in) very little change (.0001 -.0002) . The larger the part and the more machining on it, the more distortion. How to Harden 4140 Steel eHowStep 1. Heat the steel to 1,675 degrees Fahrenheit in a heat treat furnace or forge and hold it at that temperature for approximately 30 minutes per inch of length to normalize the steel. Normalizing removes any stresses within the steel that could create cracks when hardened. How to Heat Treat A-2 Tool Steel HunkerThis means it hardens rapidly compared to other tool steels, making heat treatment potentially difficult. Heat Treating Step 1 Heat the steel through to 1,560 degree Fahrenheit using a forge or heat-treat oven . Once thoroughly heated, slowly cool in the furnace by dropping the temperature 20 degrees per hour to 1,200 degrees. This relieves any

A2 is also an air-hardening tool steel but includes less than half the chromium (4.75 5.50%) and a bit less carbon (0.95 1.05%) than D2. Its highly wear-resistant and moderately tough. Like D2, it is incredibly resistant to distortion during heat treating and is moderately machinable and grindable.

S7 Shock-Resisting Tool Steel is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes it a candidate for a wide variety of tooling applications.

Heat Treating 4140 steel FAQ :anvilfire How-to.

1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use. 3) Tempering recommendations from the ASM heat treaters guide for 4140-4142 is a minimum of 400°F.
