ER316 符合:YB/T5092 2H08Cr19Ni12Mo2Si
不銹鋼焊絲 相當(dāng):AWS A5.9 ER316
ISO 14343-B-SS316
In accordance with:YB/T5902 2H08Cr19Ni12Mo2Si
Be equivalent to:AWS A5.9ER316
ISO 14343-B-SS316
說明: ER316 焊絲主要成分是18Cr-12Ni-2Mo。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)性能和抗晶間腐蝕性能,焊縫抗裂性良好;具有不增C,且Cr、Ni燒損小等特點(diǎn)。因合金含量高,耐腐蝕性能優(yōu)良。
用途: 長應(yīng)用于石油化工、化肥、尿素生產(chǎn)或儲(chǔ)存設(shè)備,如06Cr17Ni12Mo2(SUS316)等材料的焊接。
Instructions: The ER 316 welding stick consists mainly of 18Cr-12Ni-2Mo.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 low content of carbon, it has excellent inoxidability.
Use: It’s usually used to weld materials in petrochemical industry and production and storge facilities of fertilizer or urea, such as 06Cr17Ni12Mo2 (SUS316)

注意事項(xiàng):
保護(hù)氣體:注意保護(hù)氣體的純度,混合氣配比推薦Ar+1~3%O2。TIG采用純Ar。
氣體流量:20~25L/min。
干伸長度:15~25mm。
將焊接部位的銹層、濕氣、油污、灰塵等確實(shí)除凈。
室外焊接時(shí),當(dāng)風(fēng)速大于1.5m/s應(yīng)采取適當(dāng)?shù)姆里L(fēng)措施,以防發(fā)生氣孔。
以上建議僅供參考,在具體造作中以現(xiàn)場情況為準(zhǔn)。必要時(shí)先進(jìn)行工藝評(píng)定再確定焊接方案。 |
