Is It Normal For The Wear-resistant Composite Panel To Crack

- Apr 04, 2019-

1. Cause of formation: necessary to release welding stress;

2, crack specifications: a shallow interval of 10-15 mm, there is a dense transverse crack;

3, no crack: not high chromium cast iron alloy, wear resistance can not talk about;

4, small interval: insufficient stress release, resulting in peeling of the surfacing alloy layer;

5, the interval or crack is too large: affecting the wear resistance of the alloy, may cause spalling;

6. Crack inspection standard: The range of large transverse cracks in the range of 100×100 mm: 8-10 channels;
