Fig. 74 Microstructure (picral etch, 500 ) of AISI S7 tool steels with isothermal heat treatments. (a) Held at 704 C (1300 F) for 30 min (only a small amount of transformation before quenching). 7 Main Types of Tool Steels MetallurgyErosion resistance is increased by increasing the carbide content of the steels. Cobalt, when present, improves the resistance to erosion and heat checking during severe thermal shocks. Hot work tool steels, when tempered around 500°C are not allowed to attain hardness higher than 50-52 HRC, otherwise the impact strength becomes very low

Carbide Series - Grades - NTK Cutting Tools

The result of intensive reseach and development for improving carbide grades The NTK carbide grade series shows very stable performance under a wide range of conditions. NTK uses micro-grain carbide well balanced between wear resistance and toughness, as substrate.

A sudden increase in temperature of 1500/2000°F may cause tool steels to crack. Second, tool steels undergo a change in density or volume when they transform from the as-supplied annealed microstructure to the high temperature structure, austenite.

S7 is probably the most common steel used in the USA for plastic injection molds, or moulds for the rest of the world. This steel is relatively easy to machine, can be hardened to Rockwell 54-59, which is certainly hard enough for a mold. It is easy to polish to a high lustre, is easy to weld and is relatively tough.

How To Choose Material For Injection Molds, S7, P20, NAK

NAK 55 is a pre-hard tool steel which is easy to machine, hardened to 38-42 Rockwell, easy to weld and polishes nicely. NAK 80 is a pre-hard tool steel, somewhat harder and tougher than NAK 55. It can be polished to a high lustre finish, making it popular for medical and optical plastic parts. How To Choose Material For Injection Molds, S7, P20, NAK S7 is probably the most common steel used in the USA for plastic injection molds, or moulds for the rest of the world.

Advancements in production methods have helped improve steel quality and subsequent tool performance, including DC53 developed in the 1980s and the most recent generation that comprises less carbon and chromium and, hence, carbides. Fatigue strength tests show DC53 has a longer life by a factor of 10 times the life of D2, and the third S7 Steel Chemical composition, Metal Properties, Datasheet Tool & Die Steels Inc.
