Products Description
As a core load-bearing component in vacuum heat treatment equipment, the 310S Vacuum Furnace Charging Basket is specially designed to adapt to the harsh working conditions of vacuum furnaces, such as high temperature, high pressure, no volatiles, and no oxide scale pollution. It integrates excellent high-temperature resistance, corrosion resistance, and structural stability, providing a reliable solution for the safe loading, transportation, and heat treatment of workpieces in various high-end industrial fields.
The 310S Vacuum Furnace Charging Basket takes 310S (0Cr25Ni20) austenitic heat-resistant stainless steel as the core material, which is the preferred material for vacuum furnace tooling due to its unique component advantages and excellent performance characteristics. 310S stainless steel contains 24.0%-26.0% chromium and 19.0%-22.0% nickel, with a carbon content of no more than 0.08%. This high nickel-chromium composition forms a dense Cr₂O₃ passivation film on the surface, ensuring that there is no volatile matter in the high-temperature vacuum environment and no oxide scale peeling, which effectively avoids contamination of the vacuum chamber and heating elements, and also prevents workpiece rework caused by oxide scale adhesion. At the same time, the full austenitic structure of 310S stainless steel endows the charging basket with excellent high-temperature creep resistance and thermal fatigue resistance, which can stably operate continuously at 1150℃, with a maximum service temperature of up to 1200℃, and no deformation or cracking even under frequent cold and heat cycles.




Core Product Attributes & Technical Parameters
The product is constructed from 310S stainless steel with a typical chemical composition of 24%-26% chromium (Cr) and 19%-22% nickel (Ni), plus a low carbon content (≤0.08%). This composition forms the basis of its superior performance. Key technical parameters are tailored to industrial needs:
Working Temperature Range
Continuous operation at 900-1150℃, with a maximum tolerance up to 1200℃, suitable for quenching, solution treatment, annealing and other high-temperature processes.
Pressure Adaptability
Compatible with high-pressure gas quenching conditions up to 20 bar, maintaining structural integrity under extreme pressure.
Mechanical Properties
Tensile strength ≥520 MPa, yield strength ≥205 MPa, elongation ≥40%, and creep resistance of 120 MPa at 800℃, ensuring no deformation under heavy load.
Surface Quality
Mechanical polishing to Ra≤0.8μm, with pickling and passivation treatment to eliminate welding scale, avoiding workpiece and furnace contamination.
Distinctive Features & Competitive Advantages
Compared with ordinary stainless steel fixtures, the 310S Vacuum Furnace Charging Basket boasts unique advantages tailored to harsh vacuum heat treatment environments:
Excellent High-Temperature Stability
The high Cr-Ni content forms a dense Cr₂O₃ passivation film on the surface, reducing oxidation rate to 2.5mm/year at 1000℃, significantly reducing oxide scale peeling and furnace pollution.
01
Superior Thermal Fatigue Resistance
It withstands repeated heating and cooling cycles without cracking, doubling service life compared to 304/316 stainless steel fixtures, thus lowering replacement and maintenance costs.
02
Optimized Structural Design
Adopting frame-type grid structure with reasonable mesh spacing, it ensures uniform vacuum distribution and air circulation, promoting consistent workpiece heating. Reinforcing ribs are added at key load-bearing positions to enhance structural rigidity.
03
Clean & Pollution-Free Performance
No volatile impurities at high temperatures, and the polished surface prevents workpiece scratches and contamination, meeting the requirements of precision component processing.
