High Ductility Brittle Crack Arrest Wear-Resistant Steel

High Ductility Brittle Crack Arrest Wear-Resistant Steel

Quick Detail:

While ensuring unchanged wear resistance, NM450Tuf products have an impact force of up to 110J at -20°C. The low-temperature toughness is more than 2 times that of wear-resistant steel of the same level, 4 times more than the national standard requirements. It can serve in the -60°C environment and has excellent wear resistance. And the service life is doubled without increasing the cost of welding and other processing techniques.

The main materials are NM400Tuf, NM450Tuf, and NM500Tuf

High ductility brittle crack arrest wear-resistant steel is a steel developed to solve the problem of cracking in U-shaped dump truck carriages. "Crack-arresting steel" refers to steel with good fracture toughness and the ability to inhibit the propagation of brittle cracks, and has the ability to prevent cracks from expanding at high speeds. . When there are potential defects or cracks in components, the crack arresting steel can prevent the expansion of cracks within a small range and prevent major accidents under the action of dynamic load and impact load.
