FW3103 20 ℃ 50 ~ 55HRC 
 600 ℃ 38 ~ 45HRC 
 800 ℃ 28 ~ 36HRC blade and high-temperature thermal shear valve sealing surface is welded. National patent product, the national key scientific and technological achievements to promote projects products. Suitable for high temperature metal abrasion conditions, can partially substitute GoGrW alloy. 
 FW3104 20 ℃ 58 ~ 62HRC 
 600 ℃ 40 ~ 48HRC 
 800 ℃ 30 ~ 38HRC steel making, coking, sintering, cement and other industries there is high temperature wear and tear of machinery and equipment. With the FW-3102 uses, often used to withstand the impact of large parts or parts of the pressure welding. National patent product, the national key scientific and technological achievements to promote projects products. For high temperature abrasive wear with a certain impact and larger particles, the larger point of erosion conditions. Maximum cladding layers: 3 layers, the maximum cladding thickness: 8mm; transition layer with the FW-2101 welding. Maximum working temperature 900 ℃.
