 Z116 Z117 high-vanadium cast iron welding rod price 45 yuan / kg 
 Details: Description: Z116, Z117 is a low-carbon steel welding core, low-hydrogen type electrode of vanadium alloy cast iron. Weld metal ferrite to form a collective and vanadium carbide dispersion-like organization, with good crack resistance, the welding using DCRP. 
 Purpose: The electrode can be used to repair defects in cast iron, such as the cylinder body, rack gear boxes, etc., but also high-strength cast iron welding and cast iron milling. Weldment may be preheated, can be machined after welding. But the processing performance than Z308, Z408. 
 Chemical Composition of Deposited Metal (%) C ≤ 0.25 Mn ≤ 1.5 S ≤ 0.70i S ≤ 0.04 P ≤ 0.04 V8-13 Fe I 
 Reference Current (A) φ2.5 * 60-80 φ3.2 * 80-110 φ4.0 * 120-140 
 Note: 1, Z116 DCRP welding rod as far as possible, the situation in the absence of DC power, AC power can be applied, but the high number of no-load voltage requirements. The electrode performance, use and Z117 are the same. 2, the welding current as the use of small multi-layer welding. 3, before welding electrodes should be baked at 300 ℃ for 1h.
