Moreover, under these conditions, the cold working defects such as hardeningÂ and cracking may occur in the product. This chart gives you the color of the steel and the corresponding temperature in Fahrenheit. Wrought ironÂ is best forged at a temperature little below 1,290Â°C. The forging steels with vanadium or tungsten can have relatively high temperatures at which the carbide fully dissolves, though the amount of carbide is pretty small over a wide range of temperature, so the carbide volume at 1000°C is probably a better indication of forgeability in that case. Do not forge below 1500°F (815°C). Fabrication Operations– and how the product is to be made is a third-level consideration. (using tests of 24 hours duration). Excessive temperature mayÂ result in the burning of the metal, which destroys the cohesion of the metal. Also, I am interested to make new things. their carbides dissolve at forging temperatures and those carbides will form again at lower temperature. of the metal. And the bottom picture shows the sword at around 1600 degrees … The finest carbides were achieved with a forging temperature of 1050°C (1925°F); carbides were larger with either higher or lower temperature: Image from [9] With low alloy steels like O1, 1095, 52100, W1, W2, 5160, etc. After finish forging a preliminary heat treatment is performed. There are two important steps in the heat treatment process, knife forging and tempering. Normalizing: Heating steel to a temperature 30-50°C above A3 or Acm in austenite field range, soaking it at that temperature and then cooling it in still air is normalizing.

This is very important to a blacksmith because it is how the smith knows what the temperature … In Yellow Death, C-276 alloy has not exhibited pitting, even at the maximum test temperature (150°C).The Critical Crevice When the heat takes on a white color, forging with high carbon steel can be difficult. A metal must be heated to a temperature at which it will possess high plastic properties toÂ carry out the forging process. Carbon and standard alloy steels are most commonly cold-forged. Furnace cool to 1200°F (650°C) at a rate not exceeding 50°F (28°C) per hour. “Viewing many sparks may make for great photos, but it makes for poor welding.” Following are the common heat treatment processes practiced in steel forging companies. A spatial preference query ranks objects based on the qualities of features in their spatial neighborhood. The forging process involved molding the knife at a critically high heat level (typically 900 - 2,000 degrees Fahrenheit) to improve its hardness. The metal work piece is heated to a proper temperature so thatÂ it gains required plastic properties before deformation, which are essential for satisfactoryÂ forging. Most farrier tools, like pritchels and forepunches, are made from high carbon steel and can be damaged at this temperature. InsufficientÂ temperature will not introduce sufficient plasticity in the metal. “Greater heat does not help welding,” Schantz says. The expanding metal will stretch the existing grains and, if the temperature is within the forging temperature region, will recrystallize and form new strain-free grains. Once you are done forging the knife you can move on to the tempering process in which you increase the knife's flexibility and sharpness at a lower temperature, typically between 390 - 800 degrees Fahrenheit.
