How to distinguish between high chromium alloy and low chromium alloy in slurry pump components?

To distinguish between high chromium alloy and low chromium alloy in slurry pump components:

Price: Compare prices from different suppliers. If the price is significantly lower, it is unlikely to be high chromium alloy.

Hardness: High chromium alloy typically has a hardness of HRC ≥ 56. This is a relatively simple and practical method for differentiation.

Chemical Composition: High chromium alloy has a chromium content greater than or equal to 26%, while low chromium alloy has a chromium content of 20% or below.

Service Life: Low chromium alloy has a much lower wear resistance compared to high chromium alloy.

Please note that these methods are general guidelines and it is advisable to refer to specific material specifications and technical data provided by the manufacturer for accurate differentiation.
