High Temperature 310S Stainless Steel Sintering Mesh Tray For Powder Metallurgy Vacuum Furnace

Powder Metallurgy Sintering Mesh Tray, also called sinter mesh basket or heat treatment loading tray, is high-temperature resistant tooling matched for PM sintering process. It is integrally formed with woven 310S / 309S heat-resistant stainless steel mesh with reinforced wrapped edge welding.

It is placed inside vacuum sintering furnaces, mesh belt furnaces and box furnaces to carry powder compacts, cemented carbide, automotive PM gears and metal green parts during high-temperature sintering.

The hollow mesh structure enables full penetration of heat and protective atmosphere to guarantee even sintering quality. Special heat-resistant steel avoids softening, warping and oxidation scaling at 1100–1350°C, supporting repeated cyclic use, essential consumable for mass powder metallurgy production lines.

1.Mesh Surface: Plain woven high-temperature metal wire mesh with uniform holes for optimal heat and gas flow

2.Reinforced Edge: Solid stainless steel round tube fully wrapped frame, anti-deformation under load, no mesh cut during stacking

3.Welding Craft: Full seamless welding, no cracking or wire shedding under long high-temperature operation

4.Standard Material Options:

1. 310S (2520): Max temp 1350℃, best anti-oxidation, top choice for vacuum sintering
2. 309S (2320): Max temp 1200℃, cost-effective for atmosphere sintering
3. 304: For low-temperature degreasing and temporary part transfer

1.Uniform Sintering & Higher Yield: Hollow mesh design allows full circulation of H₂/N₂ protective gas, minimal temperature difference inside compacts, less cracking and dimensional tolerance defects

2.High Temp Durability & Low Consumption: 310S resists oxidation and thermal fatigue, reusable thousands of cycles. 60% lighter than cast iron trays to cut furnace power consumption

3.Lightweight & High Productivity: Easy manual loading/unloading, multi-layer stackable design to boost single batch sinter output

4.Zero Contamination To Parts: Integrated seamless welding prevents wire breakage and metal debris, eliminate black spot reject defects on PM products

5.Full Customization: Custom length width height mesh hole size frame thickness reinforced edge and handle style available

6.Simple Maintenance: Sinter residue easily cleaned by air blow or water washing, no carbon powder leftover to pollute subsequent batches

Q1: How to choose between 310S and 309S mesh trays?

A: Choose 310S for vacuum sintering over 1250℃ and long service life; select 309S for atmosphere sintering below 1200℃ to cut procurement cost.

Q2: Will the tray warp under high temperature?

A: Full wrapped thick tube edge + full welding structure effectively prevent warping under rated single-layer load; reinforced double frame design available for heavy loading.

Q3: Will fine powder leak out through mesh holes?

A: Custom dense small-aperture mesh or double-layer composite mesh to stop fine powder leakage and furnace contamination.
