Leigong Open Arc 1.6mm Manganese Hardfacing Wire Similar To AP-O
1.Chemical composition and hardness Type C Mn Si Cr Ni Mo Hardness
LZ276 ≤0.8% 12.0-16.0% ≤1.30% 12.0-16.0% ≤2.0% ≤2.0% ≥HB210

2.Properties
1) Hardfacing metal property:work harden, toughness and wear resistance.
2) Weldability: stable welding arc, good performance, lower spatter, high-usage.
3) Suitable base metal:carbon steel, low alloy steel.
4) Hardfacing thickness: no limit.
5) Anti-cracking ability:no crack checking.
6) Machining:Tunning, milling and grinding after hardfacing.
7) Diameter and package:1.6mm, 15kg/spool;2.4mm/2.8mm, 25kg/coil, 250kg/drum.
3.Application
Applied in buffer layer hardfacing,component supporting  high impact,high manganese steel,railway switch,conveyor screw,blades,hammer.
4.Optimum welding procedure parameters Diameter Current Voltage Stickout
1.6mm 250A-300A 26V-30V 16-24
2.4mm 300A-350A 26V-30V 30-35
2.8mm 320A-350A 28V-30V 30-40

5.Notes
1. Remove fatigue layer, oil and rust.
2. Stored in cool and dry place, use up within three days once opened.
