RD-138 (6686在线)
Cement grinding rolls, grinding discs, extrusion rolls, crusher rotors priming/transition layer surfacing
Product details:
RD-138
——————————————————————————————————————————————
Cement grinding rolls, grinding discs, extrusion rolls, crusher rotors priming/transition layer surfacing
Material Characteristics
The post-weld material is an extremely tough, crack-resistant cladding material with high extrusion stress, austenitic in nature, and characterized by hardening (work hardening) when impacted. | |
1.Microstructure: Austenitic chromium-manganese steel;Alloy Type:C-Cr-Mn-Fe | 2.Processing performance: only support sanding |
3.Cutting performance: does not support flame cutting | 4.Surfacing thickness: supports multi-layer surfacing |
Applications
Typically used as an overlay transition and priming layer to facilitate overlaying of harder overlay materials: e.g. transition/priming layer for overlaying of grinding rolls, grinding discs, extrusion rolls, crusher rotors; also used in the manufacture or repair of crane wheels, rope pulleys, wire-drawing discs, etc... |

Welding Precautions
1 6686平台. When using RD-138 welding wire, do not use inert gas, and pay attention to control the current and voltage according to the recommended surfacing parameters. 2 6686手机版. Oscillating and straight line welding can be, can be overlaid with multiple layers, the performance of the alloy layer and the dilution rate of the overlaid welding. 3 6686注册. Each layer of weld should be cleaned up after welding slag before welding the next layer, and so on. |
