Heat treatment of tool steels in vacuum furnaces with gas quench. Part 1. Process requirements and simulations. PhD. steels, while process simulators such as G-Quench Pro. ? enable designing of new treatment methods The high speed steels are quenched in oil or gas under pressure, down from tempera- tures of up?
Reliable supply of enrichment and quenching gas mediums expertise. Whether you are a manufacturer, metal fabricator or heat treatment expert, you need a reliable Vacuum furnaces. → Pit furnaces. → Rotary retort furnaces. All typical protective atmospheres, e.g.: → Nitrogen-methanol/endothermic gas atmospheres.
Variations in furnace type, load or part size, etc., may require varying allowances for parts to reach aim temperature. (4) Interrupted oil quench may be required for very large sections. (5) Although high speed steels may be air-hardened, a salt bath or other similar equipment is required to attain maximum hardness.
Bad habits have been, or will be, developed in heat treatment pro- .. M2 high speed steel. The size of the blocks tested were 1" × 1" × 1". (25mm × 25mm × 25mm). The test objective was to see what effect a variable soak time had on the heat treat .. If you are using an open atmosphere furnace, versus a vacuum con-.
For many years now, gas quenching has been the preferred process in the heat treatment of high-speed steels and hot and cold working tool steels. With the development of separate gas quenching chambers, it is often possible to replace oil quenching with high-pressure gas quenching using nitrogen or helium for heat?

discuss oil quenching in vacuum furnaces a technology that has been used for over 50 years and has both . Measuring the efficiency, or “speed” of an oil quench can be done one of two ways, by measuring the oil's hardenability of a steel is high enough to compensate for the slow cooling aspects of this medium .
and microstructures of water and oil-hardening grades of steel, there is relatively little or no available information on the 12” high hot zone with an integral 300 gallon oil quench tank was used for oil quenching. Nitrogen was used as the qu enchant in the. 1000 vacuum furnace, which was austenitic stainless steel.
