Product Overview

Description

Stellite 12	Meet GB	EDCoCr-B-03
Cobalt base 12 surfacing electrode	Very AWS	ECoCr-B

Description: D812 is titanium-calcium type coating, continuous casting Stellite 12 alloy welding wire as the core overlaying electrode. Can Be AC and DC dual-use, suitable for the use of DC reverse, electrode welding positive. Stable arc, good slag covering, beautiful molding. Stellite 12 alloy has good corrosion and wear resistance in a wide temperature range below 800 ° C, although it has moderate hardness in co-based alloys. The surfacing layer can be machined.

Usage: it is used for surfacing welding of high temperature and high pressure valve, sawtooth of wood, various cutting edge of chemical industry and hot finishing roll.

Mechanical properties of deposited metal (reference values)

Room temperature hardness HRC	High temperature hardness — series HV
	500℃	600℃	700℃	800℃
44-50	380	320	305	285

Notes: 1. The electrode shall be baked at 150 ° C for 1 hour before welding. 2. Small current and short arc surfacing are suitable to avoid increasing the penetration of base metal and reducing the properties of surfacing alloy.

3.According to the type of base metal and the size of workpiece, the preheating temperature of 350-500 ° C and the interlayer temperature of 350 ° C can be selected for surfacing welding.

4.According to the working condition, generally choose the workpiece after welding 600-750 ° C, heat preservation 1-2 hours later slowly cooling with the furnace, or will be placed in the dry and preheated sand or ash slowly cooling
