Shale Shaker Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for separating drilled cuttings from drilling mud on shale shakers with API-rated multi-layer screens, so the mud can be recycled downhole. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Shale Shaker Screen Is Used
- Onshore & offshore drilling: primary solids control.
- Horizontal directional drilling: mud recycling.
- Mining & geothermal: drilling fluid recovery.
- Mud cleaners: desilter underflow screens.
Ordering Shale Shaker Screen in 304 Stainless Steel
- API designation: API 60–200 per API RP 13C cut point and conductance.
- Shaker model: Frame type and dimensions must match the shaker.
- Construction: Composite or steel frame, hook strip or pretensioned.
Mistakes to Avoid with Shale Shaker Screen
- Using too coarse a screen, loading the mud with fines.
- Pressure-washing panels from the wrong side.
