Sep 09, 2017 · HOW TO AVOID STEEL HEAT TREATMENT PROBLEMS. Tool selection should occur based on the metal's hardenability and shape. vacuum furnaces, proper hardening, quenching,
Vacuum heat treatment offers an alternative method to traditional salt-bath and controlled-atmosphere furnace hardening techniques for high strength steels, such as AISI 4340M and 300M. However, heat treaters must be prudent when choosing between oil and gas quenching for vacuum hardening of high strength steels, because each process has its advantages and
High Pressure Gas Quenching Fu. it is applied for vacuum quenching high alloy steel such as high speed tool steel,mould st.<
The strength and toughness are excellent when heat treatment is appropriate, and the high temperature tempering hardness can reach 62 ~ 63 HRC. The toughness of DC53 is more prominent in cold-working die steel. The tools manufactured with DC53 rarely appear cracks and cracks, which greatly improves the service life.
Heat treatment consists of heating the metal near or above its critical temperature, held for a particular time at that finally cooling the metal in some medium which may be air, water, brine or molten salts. The heat treatment process includes annealing, case hardening, tempering, normalizing and quenching, nitriding, cyaniding etc.
Vacuum heat treatment furnace is used for high-pressure gas quenching of high-speed steel, tool and die steel, superalloy, martensitic stainless steel, titanium alloy and other materials. It can also be used for annealing of magnetic materials. Optimum design of gas quenching system and electronic control system can reduce workpiece deformation.
Advances in vacuum furnace technology, particularly in the area of high gas pressure quenching, produce microstructures with the type and distribution of carbides throughout the matrix equivalent to those microstructures traditionally limited to salt bath heat treating.
A high pressure gas quenching technology is the best heat treating solution for circulation and numismatic coining dies. Process optimization and control make it possible to achieve

Vector high pressure gas quenching furnaces are the ideal solution for heat treating. Vector is a vacuum furnace with a round graphite or all-metal hot zone. These furnaces can be used for most standard hardening, tempering, annealing, solution heat treating, brazing and sintering.
In order to prevent cracking, gas quenching and high temperature tempering are recommended to reduce heat treatment stress or to pre-process the mould embryo cavity. Heat Treatment of SKD-11 Quenching: Preheat 700-750 C, then heat to 1000-1050 C and cool in static air.
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.<
The high speed steels are quenched in oil or gas under pressure, down from tempera- tures of up to 1250 oC and then tempered within 500-600 oC. A properly performed heat treatment is decisive for the mechanical and functional properties of tools and the economy of their application.
Horizontal Twin Chamber Vacuum High Pressure Gas Quenching Furnace. It is used for vertical gas quenching of materials like tool steel, die steel, high speed steel, super high strength steel, etc. The heating chamber is separated with the quenching chamber, which saves much energy and has good cooling. read more; HIP and Gas Quenching Furnace. It is used for HIP and rapid cooling gas quench treatment of various metal, copper base, iron base powder, friction resistant material ceramic
Heat treating 101: An Introduction to Heat Treating Procedures What happens, why it's done and how it benefits steel applications. Whether you're looking for a material with wear resistance for a long service life, the ability to resist cracking following impact or a range of other characteristics, heat treating can draw out these qualities for optimal results and performance.
Vertical bottom loading gas quenching furnace is used for vertical gas quenching of materials of tool steel, die steel, high speed steel, super high strength steel, etc. It is specially applied for vacuum gas quenching of large size easy deforming products like long rod type parts, axle parts, plate type parts, etc.
Jun 14, 2019 · These vacuum furnaces are equipped with either gas (pressure) quenching or oil quenching, the latter taking place in a separate chamber. Typical Specifications Vertical vacuum furnaces with gas pressure quenching capability (Fig 1) typically operate in the temperature range of 538°C – 1315°C (1000°F – 2400°F).
Heat is applied to the part being hardened, using an oxy- acetylene (or similar gas) flame on the surface of the steel being hardened and heating the surface above the upper critical temperature before quenching the steel in a spray of water. The result is a hard surface layer ranging from 0.050" to 0.250" deep.

Nov 07, 2011 · Quenching requires forced gas cooling, and newer equipment often uses high pressures that can significantly enhance the quality of the heat treatment. Subsequent tempering usually requires multiple steps (double or triple draws) that lock the desired changes into the tool steel.
