Heavy Engineering Rolling Mill Parts Casting Foundry

TDC Alloys is an ISO 9001:2015 certified Rolling Mill Parts Casting Manufacturer in Ahmedabad, providing certified cast parts engineered to withstand extreme shock loads and continuous rolling pressure across steel plants in Ahmedabad.

Our foundry pours heavy rolling mill castings from 10 kg up to 3,000 kg per piece. Using medium-frequency induction melting and 28-element optical spectrometry, we cast mill stand housings, bearing roll chocks, mill drive pinions, wobbler couplings, and flying shear bodies throughout Ahmedabad.

Rolling Mill Metallurgy & Alloy Standards

As a specialized Rolling Mill Parts Casting Manufacturer in Ahmedabad, 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.

Mechanical Properties & Material Performance

Our programmable solution heat treatment, stress-relieving, and normalizing cycles optimize metallurgical properties for heavy mill duty:
