SAFDUR 800 E. MMA Electrodes Hardfacing

Transcription

1 SAFDUR 800 E SAFDUR 800 E is a basic-graphite coated high-efficiency MMA electrode with ~200% metal recovery depositing a hyper-eutectic chromium hard alloy with special alloying elements. Specially developed for resistance to mineral abrasion at higher temperatures <650 C, typical applications include surfacing against mineral abrasion at higher temperatures e,g in the steelmaking industry, production of construction materials and cement plants. Used for hard facing carbon steels and low alloy steels against abrasion by mineral particles and but exhibits limited resistance to impact and shock therefore number of layers should be limited to 3. The deposit is only machinable by grinding. Smooth, regular weld beads are deposited with only minimum penetration. The hardness cracks which typically appear in this weld metal are not detrimental to resistance against mineral abrasion. When welding crack sensitive base materials a buffer layer is required using 307 type MMA electrode. Flat welding position only. Shall be used in DC+ or AC mode.

2 SAFER R 400 SAFER R 400 is a thin rutile coated MMA electrode for hardfacing applications, which is very easy to use. Used for surfacing against sliding impact, e.g. slideways, shock, e.g. cams and rolling impact, e.g. rotors. Typical applications are civil works and agricultural equipment such as crane parts, rails, slideways, rope pulleys, track-supporting rollers of crawler-type vehicles, wheel flanges, stud links and others. Weld metal hardness of ~ HV1 0 in the as-welded condition, it can reach 400 HV after water-quenching. Deposit a maximum of 3 layers. Excellent weldability in all position except Vertical Down. Shall be used in DC- or AC mode. EN 14700: E Fe1 8555: E1-UM-300 C Mn Si Cr Fe All weld metal Rem. If necessary: C for 1 hour, 5 times max HV10 AC; DC- PA PB PC PD PE PF Packaging data Diam.

3 SAFER R 600 SAFER R 600 is a semi-thick basic coated rutile MMA electrode which is easy to use for hardfacing carbon steels and low alloy steels. Weld metal can be ground. Preheating up to 400 C is always necessary, specially for large workpieces. Very good resistance to medium impacts. Examples: civil works and mining equipment, shovel teeth, buckets, crawler shoes. Deposit a maximum of 3 layers. A tough buffer layer is only required in the case of very crack sensitive base metal. EN 14700: E Fe2 8555: E 2-UM-60 C Mn Si Cr Fe All weld metal Rem HV Materials Surfacing of all wear parts when a specific rigidity in service is required as well as a high hardness level with good abrasion resistance under medium impacts. Some applications: Civil works and mining equipment, mechanical shovels, buckets, crawler shoes, The SAFER R 400 electrode can be used as underlayer. If necessary: C for 2 hours, 5 times max.

4 SAFMANGA SAFMANGA is a basic coated austenitic manganese steel MMA electrode for wear resisting hard facing deposits. Weld metal will increase in hardness by cold-working (approx HB), it is therefore particularly suitable for components which are subjected mainly to wear, caused by heavy impact and shock. During welding, the workpieces should not become too hot and, if necessary, be allowed to cool down. When welding large workpieces made of austenitic manganese steel, such as crusher jaw plates, it is advisable to weld in a water bath. High welding currents and wide-weave beads must be avoided. When building up several layers, it is recommended that a buffer layer is deposited with STARINOX When welding austenitic manganese steel joints, e.g , it is preferable to use STARINOX electrodes. Suitable for hardfacing of wear resisting parts such as crusher jaw plates, crusher cones, pulverising hammers, beating arms and similar components.

5 SUPERSAFOR 60 SUPERSAFOR 60 is a thick rutile coated high-efficiency MMA electrode, 160% recovery, the weld microstructure is a hypereutectic stainless chromium hard alloy. Used for hard facing against abrasion by mineral particles not resistant to impact and shock, the deposit is only machinable by grinding. Smooth, regular weld beads are deposited with only minimum penetration. The hardness cracks which typically appear in this weld metal are not detrimental to resistance against mineral abrasion. When welding sensitive base materials a buffer layer deposited with STARINOX is required. Typical applications include hard facing subject to mineral abrasion, e.g. by sand, gravel, coal, soil, clay and related minerals used in ceramics, cement and concrete building materials and mining.
