Stainless Steel Weld Tee usually uses better tap materials. Adding special alloy elements to ordinary high-speed tool steel can significantly improve the wear resistance and toughness of the tap.
Coating titanium nitride coating on the tap thread surface can significantly improve the wear resistance, heat resistance and lubricity of the tap. Appropriately increase the tap rake angle. However, it should be noted that if the tap rake angle is too large, it is easy to cause tap edge collapse and multi-edge tapped threads when the tool is withdrawn. Appropriately increase the amount of tap back relief.
However, it should be noted that if the amount of back relief is too large, it is easy to cause chips to be stuffed into the tap back angle when the tool is withdrawn, and the tapped thread finish is poor. Reasonably select the tool heat treatment method to take into account the hardness and toughness of the tap.
