Monel 500 Square Rods
The chemical composition of Monel 500 Square Rods includes 63–70% nickel and 28–34% copper, with small additions of iron, manganese, silicon, and columbium/tantalum. This unique composition imparts superior resistance to seawater, acids, and chloride stress cracking, making them suitable for aggressive chemical and marine environments. The alloy maintains stability at elevated temperatures, which makes it reliable for critical engineering components.
From a mechanical property perspective, Monel 500 Square Rods exhibit a tensile strength of 620–850 MPa and a yield strength of 345–585 MPa, along with elongation values of 20–35% and hardness ranging from 180–220 HB. These properties make the rods strong yet ductile, allowing them to be machined, fabricated, and welded without compromising structural integrity.
Monel 500 Square Rods are high-strength, corrosion-resistant nickel-copper alloy rods produced for demanding industrial applications. Manufactured, stocked, and exported by Rose Metal Industries, these rods cater to industries across Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and Andaman and Nicobar Islands.
