750C Vacuum Tempering Furnace
1. Structural characteristics of 750C vacuum tempering furnace The heating chamber mainly adopts an all-metal screen structure, with less deformation and small thermal inertia, suitable for low-temperature tempering Use, long life and easy maintenance. The nickel belt heater is adopted, which is ...
Vacuum Furnace Maintenance
Routine maintenance of vacuum furnace 1. Routine Maintenance of Equipment Including the replacement of the vacuum pump oil, the replacement of the vulnerable parts of the heating chamber, the replacement of the insulating parts, the replacement of the wearing parts of the vacuum furnace body, et...
SCM440 Heat Treatment Furnace
SCM440 is a commonly used steel grade for the production of high-strength fasteners. The product has the advantages of stable composition, low harmful elements, high steel purity, small decarburization layer, and few surface defects. It is easy to perform spheroidizing annealing and cold heading ...
Effect of Sintering Temperature on SIC/B4C Multiphase Ceramics
In the material design, the ratio of Al2O3/Er2O3 is close to 80:20, and domestic micron-level SIC powder is used, and the powder particle diameter is D50=1.5um. The Al2O3/Er2O3 powder is selected as the sintering aid, with a purity greater than 99.5%, and a mass fraction of the additive of 10%, i...
T4 Vacuum Hardening Furnace
T4 steel is a tungsten series general cobalt-containing high-speed steel. Compared with W18Cr4V, the red hardness and high temperature hardness are slightly higher, but the toughness is lower. After quenching, the surface hardness can reach 63-66HRC. 1. Features of T4 Steel The characteristics o...
17-4ph, h900 Oil Quenching Furnace
17-4PH is precipitation hardening steel, the implementation standard: ASTM A564/A564M-2013 1. 17-4ph Product Features 17-4PH alloy is a precipitation, hardening, martensitic stainless steel composed of copper, niobium/columb. This grade has high strength, strength (up to 3000 C/572o F) and corro...
20CrMo Heat Treatment Furnace
Alloy structural steel 20CrMo is a kind of steel with high hardenability, no temper brittleness, good weldability, low tendency to form cold cracks, good machinability and cold strain plasticity. 1. Chemical Composition (℅) C Si Cr Mn Mo 0.17～0.23 0.17～0.37 0.80～1.10 0.40～0.70 0.15～0.25...
Tools Steel Oil Quenching
Adding a certain type and quantity of alloying elements on the basis of carbon tool steel is called alloy tool steel. Compared with carbon tool steel, alloy tool steel has higher hardness and wear resistance, and also has better hardenability, red hardness and tempering stability. 1. Low Alloy Cu...
Stress Release Annealing Furnace
1. Principle of Stress Release Annealing The cold-deformed metal is heated at a temperature lower than the recrystallization temperature to remove internal stress, but still retains the effect of cold work hardening. This heat treatment is called stress relief annealing, or low temperature anneal...
Application of Computer Simulation Technology in Heat Treatment Process Equipment
The design of heat treatment equipment not only affects the quality of the workpiece after treatment, but also affects the service life and efficiency of heat treatment equipment.The traditional heat treatment process equipment design mostly relies on the experience data, the work quantity is lar...
