Raajratna Metal Industries Limited Usmanpura, Ahmedabad, Gujarat

The MIG Wires are supplied in Bright as well as in Matte finish and the wire is specially cleaned to avoid weld contamination. MIG wires can be supplied in plastic spools & metallic baskets. The wires have suitable cast helix to ensure perfect “pay-off”.

The Stainless Steel Spring wires can be supplied in ½ hard, ¾ hard & full hard conditions as well. We are using drawing lubricants from CONDAT and also of Japanese origin.

Raajratna manufactures clean & layer wound wire for submerged arc welding from 1.60 mm (0.062″) to 5.00 mm (0.187″) in various grades in bright as well as in matte finish. The wires tensile strength, helix and cast diameter is engineered to precise tolerance to ensure perfect “Pay-Off”.

Elongation : Aj = 100 mm marked before tension measured after tension to fracture measuring point 2.5 x diameter from fracture. A10 = Diameter x 10 marked before tension measured after tension to frature measured across fracture. Approval: We can also supply Stainless Steel rebars/coils as per ASTM A 955 / 1259 & EN standards. We are applying for German approved for Stainless steel rebars / Coils as per DIN 488 standard.   The grade of reinforcement steel will depend upon type of corrosive atmosphere For moderate atmosphere high yield reinforcement steel like 1.4301 (304) can be used. For more severe corrosive atmospheres 1.4401 (316), 1.4429 (316LN), 1.4436 (316) & 1.457 ( 316Ti) can be used. For high aggressive atmospheres duplex steel 1.4362, 1.4462 (2205) is recommended.
