Name of repair: High fierce steel turnout frog
Material: ZGMn13

Basic situation: The new high-strength steel frog is about 200HV. During the use of the wheel, the surface hardness gradually reaches 400HB. Before reaching the secondary hardness, the front end of the fork core is easily 0- The surface wear at 100mm is about 5mm. Make the front end of the fork core lower.

Repair requirements:

The hardness is 400HB, and the mechanical properties testing (strength, hardness, impact, metallography, bonding) is performed in accordance with national standards. The ideal thickness is 5MM (high manganese steel material has high carbon content, and carbides are precipitated under high temperature conditions. Metallurgical fusion and formation of brittle and hard structure).
