供应不锈钢焊丝 ER309 |
ER309 符合:YB/T5092 H12Cr24Ni13Si
不锈钢焊丝 相当:AWS A5.9 ER309
In accordance with:YB/T5092 H12Cr24Ni13Si
Be equivalent to:AWS A5.9 ER309
ISO 14343-A-G 22 12 H
说明:ER309焊丝主要成分是22Cr-12Ni。配用SJ601不锈钢碱性烧结焊剂,其焊缝金属具有良好的力学性能,抗裂性能、抗晶间腐蚀性能,具有不增Si、不增C,且Cr、Ni烧损小等特点。因合金含量高,耐高温性良好。
用途:常用于碳钢与不锈钢异种材料焊接或应用于韧性较差的马氏体、珠光体不锈钢焊接。如石油化工、火力发电站等行业。
Instructions :The ER309 welding stick consists mainly of 22Cr-12Ni. It coordinates with the stainless steel alkaline sintered flux SJ601.It’s welding line metal has good mechanical properties and resistance ability to intergranular corrosion and crack .It would not increase Si or C and would burn little Cr and Ni. Due to a high content of alloy ,it has good high thermal resistance ability.
Use :It’s usually used to weld carbon steel and stainless dissimilar materials ,sometimes to weld martensite and pearlite steel with poor toughness ,in petrochemical industry ,fire power station and other industries.
