Ragnar Welding Supplies is one of the leading manufacturers and distributors of duplex and super duplex steel MIG and TIG filler rods and welding wires with its headquarters in Jakarta, Indonesia. Our products are designed to be highly strong, resistant to corrosion, and also long lasting; hence, they are suitable in the harsh industrial environments. Ragnar Welding Supplies provides high quality, precision engineered consumables, used in the oil and gas, chemical processing, petrochemical and marine industries, and these products are of international quality. To deliver quality results, customer satisfaction is guaranteed, we offer welding systems that achieve uniform performance, high weldability and structural life, making us a reliable partner to professional welders and industrial customers everywhere in Indonesia and even further.
Duplex and super duplex steel MIG and TIG filler rod welding wires have balanced austenite and ferrite microstructure that is very strong and has great corrosion resistance. The common chemical make-up is 22-25% Cr, 4-7% Ni, 3-5% mo and 0.14-0.25% N, depending on grade. Tensile strength 750900 MPa, yield strength 500650 Mpa, and elongation 2025%. These consumables offer high levels of resistance to stress corrosion cracking, pitting, and crevice corrosion and this results in them being the most suitable in welding duplex and super duplex stainless steel in industrial, marine, and chemical applications where the resistance to stress corrosion cracking, pitting, and crevice corrosion is highly required.
Ragnar Welding Supplies Indonesia
At Ragnar Welding Supplies, we take pride in being one of Indonesia’s trusted suppliers of high-quality welding consumables. Our expertise lies in Duplex and Super Duplex Steel MIG and TIG Filler Metal, engineered for precision, durability, and resistance to corrosion.
