Qingyun Hongsheng Machinery Parts Co., Ltd. is one of the most reliable manufacturers and suppliers of 304 stainless steel heat treatment tray in China. We warmly welcome you to wholesale high quality 304 stainless steel heat treatment tray at low price from our factory. If you have any enquiry about quotation, please feel free to email us.
The 304 stainless steel heat treatment tray is an essential loading tool for medium and low-temperature heat treatment production lines. It is widely used for tempering, aging, annealing, nitriding, and soft nitriding processes. In mass heat treatment production, ordinary iron trays and low-quality stainless steel trays are prone to high-temperature deformation, oxidation, rust, peeling and slag falling. These defects lead to increased workpiece contamination, higher defective rates, frequent tray replacement and repeated equipment downtime, greatly raising factory consumable costs and time costs.
Products Description
We specialize in manufacturing high-quality 304 stainless steel heat treatment trays designed exclusively for working temperatures below 750°C. Made of genuine standard 304 stainless steel and constructed with full reinforced welding technology, our trays deliver excellent high-temperature resistance, oxidation resistance, corrosion resistance and thermal fatigue resistance. They can be recycled in furnace operations for a long time without bending deformation, slag shedding or workpiece contamination. With stable performance and prolonged service life, our trays serve as a cost-effective and customizable solution for mass production, cost reduction and global export trade.
Core Product Advantages
1. Genuine 304 Stainless Steel, Zero Workpiece Contamination
Adopting standard 0Cr18Ni9 stainless steel raw material with stable nickel and chromium composition, our trays feature outstanding high-temperature oxidation resistance. They withstand harsh furnace heat and humid workshop environments without rusting, peeling or generating oxide slag. Effectively avoiding surface defects such as stains, pinholes and impurities on precision hardware, auto parts and mechanical components, they fully meet the high cleanliness requirements of precision heat treatment production.
2. Stable Performance at 750°C, Excellent Thermal Fatigue Resistance
This 304 heat treatment tray supports long-term continuous operation at 750°C and can withstand short-term temperature spikes up to 850°C. Optimized for repeated heating and cooling cycles in medium and low-temperature processes, it resists bending, collapsing and cracking after long-term cyclic furnace use. Its service life is significantly longer than ordinary carbon steel trays and 201 stainless steel trays, effectively reducing frequent replacement costs and production downtime.
3. Full Reinforced Welding, Stable Loading & Uniform Heating
The entire tray is fully welded with thickened reinforced borders and full dense solder joints, eliminating hidden troubles such as virtual welding, desoldering and crack welding. Equipped with hollow grid and punching ventilation structures, the tray allows smooth hot air circulation inside the furnace. Workpieces are heated evenly, effectively solving common production problems including uneven hardness, inconsistent color difference and poor batch stability, ensuring reliable and consistent heat treatment quality.
4. Perfectly Matches Medium & Low-Temperature Processes, Higher Cost Performance
Most heat treatment factories mainly operate under 750°C medium and low-temperature processes. There is no need to purchase high-cost 2520 or 253MA high-temperature heat-resistant steel trays with redundant performance. Our 304 stainless steel trays fully meet the performance requirements of tempering, aging, annealing and nitriding production. While ensuring stable production and high yield rates, they greatly reduce tooling procurement costs and become the most economical choice for mass production lines.
5. Full Customization, Compatible with All Types of Heat Treatment Furnaces
We provide comprehensive non-standard customization services according to customers' furnace cavity size, equipment type, workpiece weight and placement method. Multiple shapes are available including square, round and basket types, together with grid hollow, perforated ventilation and thickened solid border structures. Plate thickness, hole size and outer frame dimensions can be adjusted freely to perfectly match box furnaces, pit furnaces, trolley furnaces and atmosphere protective furnaces.
6. Export Compliant, Supporting Global Trade Orders
As conventional industrial hardware consumables, 304 stainless steel heat treatment trays have no special export restrictions and support smooth customs clearance. We can provide complete material test reports, factory quality certificates and full specification documents for export procedures. Standard export packaging and sea/air transportation are supported. Our products are exported in bulk to Southeast Asia, the Middle East, Europe, Africa, South America and other global regions with stable quality and high customer repurchase rates.
Application Scenarios
✅ Recommended Working Conditions (Medium & Low Temperature Exclusive)
Aging hardening treatment of aluminum alloy and titanium alloy parts (500–700°C)
Tempering process of carbon steel, alloy steel and mold steel workpieces (500–650°C)
Low-temperature annealing and stress relief for hardware and mechanical parts
Nitriding, soft nitriding and atmosphere-protected low-temperature heat treatment
Batch standardized heat treatment for new energy accessories and precision components
❌ Non-Recommended Working Conditions (Professional Reminder)
Continuous high-temperature quenching and intensive carburizing above 900°C
Long-term high-temperature bearing operation for super-heavy workpieces
For ultra-high temperature, heavy-load and strong carburizing working conditions above 900°C, we recommend 253MA or 310S/2520 heat-resistant steel trays to avoid high-temperature deformation and equipment loss, ensuring long-term stable production.

Why Choose Our 304 Heat Treatment Trays?
Many low-cost trays on the market adopt thin plates, impure materials, sparse welding and rough craftsmanship, resulting in rapid deformation, cracking, peeling and rusting after short-term use, which increases rework costs and replacement frequency. We insist on using genuine 304 stainless steel raw materials, full-thickness plates and precision full welding technology. Every batch of trays undergoes strict factory inspection on flatness, bearing capacity and welding strength to eliminate quality risks from the source.
Direct factory supply without middleman markup, offering prominent cost performance
