1. What is a high temperature alloy?<\/p>\n\n\n\n

High-temperature alloys broadly refer to a type of alloy that is more resistant to high temperature than ordinary metal materials, and usually refers to a type of alloy with a long-term use temperature higher than 500\u2103. However, the commonly referred to as high-temperature alloy refers to a special type of alloy, such as the deformed high-temperature alloys such as GH2132, GH3128, GH3030, GH4169, etc., as well as cast high-temperature alloys, powder metallurgy high-temperature alloys, dispersion-strengthening high-temperature alloys, and intermetallic compound high-temperature materials.<\/p>\n\n\n\n

2. What are high-temperature alloy welding wires and high-temperature alloy wires?<\/p>\n\n\n\n

The high-temperature alloy wire used for welding refers to melted cold drawing wires such as arc welding and gas protective welding.<\/p>\n\n\n\n

3. What are the reference technical standards for welding wires used for welding?<\/p>\n\n\n\n

Sample sampling method and allowable chemical composition deviation for GB\/T222 steel<\/p>\n\n\n\n

Chemical analysis method of GB\/T223 steel and alloy<\/p>\n\n\n\n

General provisions on GB\/T2103 wire acceptance, packaging, marking and quality certificates, etc.<\/p>\n\n\n\n

GB\/T14992 Classification and grade of high-temperature alloys and intermetallic compounds high-temperature alloy materials<\/p>\n\n\n\n

GJB5307 Alloy Chemical Components Alloys for Aerospace<\/p>\n\n\n\n

4. What is the difference in the smelting process of high-temperature alloy welding wire?<\/p>\n\n\n\n

Generally, smelting is carried out in the following ways:<\/p>\n\n\n\n

Electric arc furnace<\/p>\n\n\n\n

Electric arc furnace + electroslag remelting<\/p>\n\n\n\n

Arc furnace + vacuum self-consumption remelting<\/p>\n\n\n\n

Double vacuum process<\/p>\n\n\n\n

Non-vacuum induction furnace + vacuum self-consumption remelting<\/p>\n\n\n\n

Non-vacuum induction furnace + electroslag remelting<\/p>\n\n\n\n

More than a dozen different processes<\/p>\n\n\n\n

5. Shanghai AVIC Group’s high-temperature alloy welding wire is usually supplied in a straight wire or a disc wire. There are a large amount of stocks, GH4169 welding wire, GH3128 welding wire, GH3030 welding wire, GH2132 welding wire, etc.<\/p>\n\n\n\n

6. What are the supply statuses of high-temperature alloy welding wire?<\/p>\n\n\n\n

Usually there are: cold pull state (hard state), semi-hard state, bright solid solution delivery, bright return delivery, solid solution + pickling state delivery<\/p>\n\n\n\n
