Composite surfacing repair of ZGMn17 super high manganese steel hammer

The composition characteristics and welding performance of the ultra-high manganese steel hammerhead with the material of ZGMn1 7 were analyzed. The surfacing welding repair test showed that the composite surfacing welding process of “base metal + intermediate transition layer + wear layer” should adopt H1Cr2. The 1Ni1 0Mn6 welding wire is supplemented by a reasonable welding process surfacing welding layer, which can successfully repair and repair the ultra-high manganese steel hammer.

Mini Steel Tape Measure

1. Features of tape measure

Gift rulers are used for advertising and promotion. They are divided into Steel tape (steel tape) and leather tape (PVC plastic fiber tape). They are usually cute and compact. Tape measures are also called measuring tools. Eighty-five percent of the world's tape measures are exported from China.

2, the characteristics of the tape measure

(1) The tape measure is too deformed and will not fail

Why didn't it fail? The spring in the tape measure is very long, and its range from completely relaxed to fully tightened is very large. The entire stroke of the tape measure includes it, and there is a margin at both ends, so the tape measure will not fail.

(2) Pull one meter long and pull two meters long, there is no difference in tension

The spring of the tape measure is very thin, and the amount of deformation when it is tightened is also small, so the reaction force is very small, and the force change is not felt when the rule is pulled.
