	Which materials are used for making the dies in open die forging? Where can I find a database of these materials' mechanical and thermal properties? How are the dies made? I'm a mech freshman and I'm just reading about open-die forging as a special interest. P.S.- Which kind of die is used to compress which metal?

	In my forge shop, most open-die, (cogging), dies are made of chromoly. In extreme cases, inconel. A wealth of information here: AMS_Handbook and here: Chromoly_Die_Stock To answer your questions would require volumes. Read up a bit and I would be more than happy to help you with your inquiries. __________________ I go into every human encounter expecting to be framed for a crime I didn't commit. Dilbert, 2013

	Dear DeltaS, Material Selection for Hot Forging dies & Toolings, is generally done by considering the following two main factors that are imposed on the Dies : 1. Type of Loads. 2. Temperatures. Factors to be considered before deciding the Tool Materials are as follows : 1. Type of Forging Equipment. 2. Material to be forged. 3. Part size & shape. 4. Type of Lubrication. 5. Quantity to be forged. 6. Rate of Production. Further important factors about Die Material are as follows: 1. Hardenability. 2. Wear resistance. 3. Resistance to plastic deformation. 4. toughness. 5. Resistance to shock loading. 6. Resistance to Thermal & mechanical fatigue. Low alloy steels such as 6 F2 are commonly used for die blocks while forging carbon steel parts And H11 or H12 or H13 for die blocks & die inserts with die steel hardness range 40 to 47 HRc for alloy & stainless steel parts. I agree with Bricktop about ASM Handbook. We use it regularly. It is one of best source books created by experts. As Mech Freshman, you may consider to become a member of ASM International chapter in your area. Good Luck. Rangasamy __________________ Let noble thoughts come to us from every side.
