JTH-700

JTH-700

Characteristics and Applications:
JT-H700 deposits a self-hardening martensite structure. it is  suitable for pump impeller, cutter blades, agitator propeller, sugar cane hammers and bulldozing parts.
Notes on usage:
1.Dry the electrodes at 80-120℃ for 60 minutes before use.

2.Clean up the contaminations on the steel.

3.Take the back-step method to prevent blowhole at the arc starting.

4.Preheat the plates and keep the inter-pass temperature above 200℃ to prevent cracking.

5.Using low hydrogen electrode for buffer layer on difficult-to-weld steels.
