ER308L不锈钢焊丝 H00Cr21Ni13

Zander stainless steel welding wires


ER308L                    
不锈钢焊丝
说明：ER308L焊丝主要成分是低C-18Cr-8Ni。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，抗晶间腐蚀性能、抗裂性良好；具有不增Si、不增C，且Cr、Ni烧损小等特点。
用途：广泛应用于石油化工等行业，如022Cr19Ni9（SU304L）等材料的焊接。
Instructions:  The ER308L welding stick consists mainly of low C-18Cr-8Ni. 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 widely used to weld materials in many industries like petrochemical industry, such as 022Cr19Ni9(SUS304L).

Cautions ：
Consumers should pay attention to the purity of the shielding gas .The recommended gas mixture ratio is Ar and 1~3%O2。The TIG should use pure Ar.
The gas flow rate is 20~25L/min.
The elongation length is 15~25mm.
The rust scale ,moisture,oil stain and dust in the welding position should be definitely cleaned.
When welding outdoors with over 1.5m/s wind speed ,appropriate wind proof measures should be taken ,in case of air vent .
The suggestions above are for reference only .The specific operation is subject to the actual situations. If necessary ,consumers should evaluate the technical qualification before determining the welding scheme.
