备注 ，一公斤为一口价的价格哦。
Sandvik 29.9 (Welding wire)
Sandvik 29.9 is a filler material suitable for joining dissimilar steels and for overlay welding of carbon and low-alloy steels, suited for MIG/MAG-, TIG-, plasma-arc and submerged-arc welding. It gives an ferritic-austenitic structure with a high ferrite content.
Even with considerable dilution by austenite forming elements such as nickel, the micro structure remains ferritic-austenitic and thus highly resistant to weld metal cracks and fissures. Sandvik 29.9 is available as wire and rods.
