On the Suitability of ASTM 532 IIB Cr White Cast Irons for Erosion-Corrosion and Abrasion-Corrosion Applications
Bibliographic record
Abstract
Abstract In this paper, two commercial Cr white cast irons, conforming to ASTM 532 IIB (15CrMo) and ASTM 532 IIIA (27Cr) respectively, have been studied under slurry jet erosion, Coriolis scouring erosion, slurry sliding abrasion and slurry pot erosion-corrosion conditions. The results show that 15CrMo performs considerably better than the 27Cr counterpart under most of the test conditions but is only slightly better in the erosion-corrosion test. Based on analyses of various components of tribo-corrosion synergy and the testing results, it is suggested that it may be beneficial to more broadly use the 15CrMo white cast irons to replace the ASTM 532 IIIA higher Cr alloy in erosion-corrosion/abrasion-corrosion applications where the intensity of damage due to mechanical effect (pure erosion/abrasion) is severe such as in the handling of thick slurries.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
