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(fā)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 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.

注意事項：

1. 焊接線能量的大小將直接影響到焊縫的力學性能。用戶根據實際情況調整線能量，重要結構盡可能采用小的線能量。

2. 焊接區(qū)域因嚴格去除油、銹、水分等雜質。

3. 以上焊接參數僅供參考。

Cautions and operations points ：

1. The energy of the bonding wire directly affect the mechanical properties of the welding line .Consumers should adjust the energy of the bonding wire according to actual conditions. The important structures should use as small energy of the bonding wire as possible.

2. The welding area should be strictly removed of oil, rust, moisture and other impurities.

3. The welding parameters above are for reference only.
