Rolling Mill Metallurgy & Alloy Standards
As a specialized Rolling Mill Parts Casting Manufacturer in Gujarat, TDC Alloys pours certified fatigue-resistant, high-impact, and wear-resistant alloys:
Adamite & Alloy Cast Steels (Cr-Ni-Mo Formulations)
Optimum combination of high tensile strength and moderate hardness (40 - 55 HRC) for roughing rolls, intermediate stands, mill pinions, and roll chocks.
High-Chromium White Cast Irons (ASTM A532 Class III 18% to 27% Cr)
Dense chromium carbide microstructure yielding 58 to 65 HRC for extreme abrasive wear resistance in wire rod finishing guides, mill aprons, and wear liners.
High-Strength Cast Steels (ASTM A148 Gr. 90-60, 105-85 & 130-115)
Superior fracture toughness and cyclic fatigue resistance under severe mill reversing shocks for mill stand housings, drive spindles, and wobblers.
Spheroidal Graphite (SG) Pearlitic Irons (EN-GJS-700-2 / 800-2)
High thermal fatigue endurance and vibration damping for structural section mill rolls, bearing chocks, and mill coupling boxes.
