详情

LINCORE® 55熔敷金属为马氏体基体+残留奥氏体混合组织，洛氏硬度50-59 RHC，可抵抗金属间滚动/滑动磨损及中度磨料磨损；通过规范控制预热温度（推荐200-250℃）和层间温度（≤300℃），可实现多层堆焊无裂纹

产品特性

  • 熔敷层具有优异的抗金属间滚动/滑动磨损性能，同时可承受中度磨粒磨损
  • 适用于碳钢、低合金钢及高锰钢
  • 在遵守预热规范和层间温度控制的工艺条件下，堆焊层数不受限制

典型应用

  • 港口起重机行走轮
  • 离心式鼓风机叶片
  • 铁路轨道端部
  • 矿山料车导轨
  • 冶金轧机凸轮及辊道转台

焊接位置

  • 平焊及横焊

NOTES

Note
Cold parts should be warmed to at least 25°C (75°F). Higher preheat of 150 - 260°C (300 - 500°F) may be necessary on thick parts or heavy sections.
Interpass temperatures between 150°C (300°F) and 200°C (400°F) do not affect the hardness of Lincore® 55 significantly.
