ER309          符合：YB/T5092 H12Cr24Ni13Si

不銹鋼焊絲                           相當(dāng)：AWS A5.9 ER309

      ISO 14343-A-G 22 12 H

                                   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(jié)焊劑，其焊縫金屬具有良好的力學(xué)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(yīng)用于韌性較差的馬氏體、珠光體不銹鋼焊接。如石油化工、火力電站等行業(yè)。

Instructions：The ER309 welding stick consists mainly of 22Cr-12Ni. It coordinates with the stainless steel alkaline sintered flux SJ601. It’s welding line bl 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.
