Stainless Steel

We specialize in the processing of Stainless Steel Wires and Bars in Martensitic and Austenitic Steel to various popular grades and are more active in Grades like SS-410, SS-420 C, SS-440 C in Martensitic Steel and 303, 304/304 L in Austenitic Steel. We supply these steels in wire form from 4.00 mm to 22.00 mm dia and in bar form upto 50.00 mm dia in various tensile strengths for making of machine components of wires for redrawing.

Supreme is highly-regarded in the industry for its excellence in the production of Drawn Wire. We use a wide range of drawing lubricants depending on the type of wire to be drawn, reduction required, and other mechanical and physical properties required. Wire supplied by us is in the wide range of 2 mm to 28 mm dia. To provide crack and defect-free steel to the Auto and other engineering industries, drawn wires are straightened in de-coiling machines for further polishing and grinding / peeling to remove surface blemishes for close tolerance and better mechanical properties.
