Screw Conveyor Flight (high chrome)

Why High Chrome Material for Screw Flights?

In a shot blasting environment, the screw conveyor flight is constantly scoured by steel shot, grit, sand, and other abrasive media. Mild steel or standard carbon steel flights wear out quickly, leading to frequent replacements and machine downtime.

High chrome (high chromium white iron) offers significantly better resistance to abrasive wear. The hard carbides in the microstructure provide a durable wearing surface that extends the interval between change-outs. For maintenance teams and plant engineers, this means less frequent shutdowns, lower spare parts consumption, and more consistent media conveying.

Compatibility and Fitment

This screw conveyor flight is intended as a replacement spare part for various shot blasting and abrasive recovery systems. It is not a universal component. Flight outer diameter, inner diameter (bore), pitch, thickness, and hand (right-hand or left-hand) must match your existing screw conveyor.

To help us quote the correct flight, please share the following with your enquiry:

• Machine make and model (if known)
• Flight outer diameter (OD) and inner diameter (ID)
• Pitch and thickness
• Hand of flight (right-hand or left-hand)
• Quantity required

SPA2Z does not publish a generic interchange list because screw conveyor dimensions vary between OEMs and machine generations. We verify compatibility case by case based on the details you provide.

Wear Life and Replacement Frequency

The actual service life of a high chrome screw conveyor flight depends on several operating factors: type and hardness of abrasive media, media flow rate, conveyor speed, and hours of operation per day. High chrome flights typically outlast standard carbon steel flights by a factor of 2x to 4x in dry abrasive conveying applications, but this is a field estimate and not a guaranteed lifespan.

We recommend keeping a spare flight set on your shelf if your shot blasting operation runs continuously or if downtime is costly. Regular inspection of flight edge thickness helps plan replacements before failure.
