Open Arc Wire Teromatec Oa3205 1.60mm 15.0 Kg

Mechanical properties

• High chromium manganese austenitic alloy for wear.
• Preventive coating of carbon steels, low or high alloy steels and 14% manganese steels.
• Maximum resistance to heavy impact and compression.
• High resistance to cracking and plastic deformation.
• Rapid work hardening characteristics.
• Machineable, rust free deposits.
• Easy slag removal.
• Low metal / metal friction coefficient.
• Maximum service temperature 300°C.
• Core de-oxidisers tolerate air currents or draught effects.
• Relatively thick, wide overlays possible in single pass.
• No enforced stop – starts increase welding duty cycles.
• Superior electrode efficiency due to low flux to metal ratio.
• Variable electrode stick out capability improves control over heat input, dilution, deposition rate, visibility and access in tight spaces.

For buttering layers prior to harder overlays and wear-preventive coating of crane rollers, crusher cylinders, shovel buckets, mobile crane rails, rail points, coupling of rolling mill extensions, shovel teeth, hammers etc.

Preheating
Preheating depends on the steel’s Carbon Equivalent, the work piece size, thickness and geometry.

Note that 12-14% Mn steels should never be preheated and the work piece temperature during welding should be kept below 250°C.
