ER309 符合:YB/T5092 H12Cr24Ni13Si
不銹鋼焊絲 相當:AWS A5.9 ER309
In accordance with:YB/T5092 H12Cr24Ni13Si
Be equivalent to:AWS A5.9 ER309
ISO 14343-A-G 22 12 H
說明:ER309焊絲主要成分是22Cr-12Ni。配用SJ601不銹鋼堿性燒結焊劑,其焊縫金屬具有良好的力學性能,抗裂性能、抗晶間腐蝕性能,具有不增Si、不增C,且Cr、Ni燒損小等特點。因合金含量高,耐高溫性良好。
用途:常用于碳鋼與不銹鋼異種材料焊接或應用于韌性較差的馬氏體、珠光體不銹鋼焊接。如石油化工、火力發電站等行業。
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.
