It can be used to get a good scrub. And heat resistant. But the weld will be machined to make it difficult. If there is no heat action after welding.


Notes on usage:

1) Generally, the workpiece should be heated at 150 ° C or more before welding.
2) after welding If it can be heated at 600ºC, it will be better. To prevent cracking.
