D256
SZESHANG
831110
1. Description
D256 is a surfacing electrode made from high-manganese steel with a low-hydrogen potassium coating. It is suitable for both AC and DC welding (for AC, the no-load voltage should not be lower than 70V). For surfacing welding, it is recommended to use a small current and narrow welding passes. After welding, the red-hot material should be hammered or water-quenched to minimize cracking tendencies. The resulting surfacing metal is austenitic high manganese steel, known for its work-hardening properties, toughness, and wear resistance.
D256 is ideal for surfacing welding on various components, including:
Crushers
High manganese rails
Buckets
Bulldozers
Pre-welding Preparation: Bake the electrode at 300-350ºC for 1 hour before use.
Worn Parts Treatment: Before surfacing worn high manganese steel parts, remove the fatigue layer or treat it with water toughness. Alternatively, use a chromium manganese steel electrode (e.g., D277).
Ventilation: Due to significant yellow smoke produced during surfacing welding, ensure adequate ventilation and operate in a well-ventilated area.
2.5mm x 300mm: 5kg per inner box + plastic bag
3.2mm x 350mm: 5kg per inner box + plastic bag
4.0mm x 400mm: 5kg per inner box + plastic bag
ISO 9001

The slag produced is full and compact when hardened, making it easy to remove.
TYPICAL OPERATING PROCEDURES: (AC,DC)
| Diameter (mm) | 3.2 | 4.0 | 5.0 |
| Current (A) | 70-90 | 100-140 | 150-180 |
| Items | C | Mn | Si | Others |
| Requirements | ≤1.10 | 11.00-16.00 | ≤1.30 | ≤5.00 |
Q1: Can I have a sample for testing?
A: Yes, we can support free sample.
Q2: Can I add my logo on the boxes/cartons?
A: Yes, OEM and ODM are available from us,for the MOQ for OEM/ODM talk with us please.
Q3: What are the benefits of being a distributor?
A: Special discount Marketing protection.
Q4: Do you have inspection procedures for welding wires and welding electrode?
A: 100% self-inspection before packing. We provide Quality Certification for every order.
Q5: Can we mix itmes in one 20FT container?
A: Yes,welding wire and welding electrode can mix them in one container.
Q6: Can I have a visit to your factory before the order?
A: Sure, welcome your visit of factory, or we can have a online meeting for factory inspection.
Q7: What is the lead time for samples and mass production?
A: Samples can be ready within 3-5 working days. For mass production, it usually takes 15-25 working days, depending on the order quantity and customization requirements.
Q8: What payment terms do you accept?
A: We accept T/T (30% deposit in advance, 70% balance against B/L copy), L/C at sight, and Western Union for small orders. Other terms can be negotiated for long-term cooperation.
