Unifit Fastener is a reputable manufacturer and supplier of Monel washers in India and serves its clients in various cities. We are experts in making washers of different sizes, shapes, and specifications to the custom demands, and these are in compliance with the national and international standards of quality.
Monel is a low-carbon, low-iron, low-manganese and high-silicon, high-performance nickel-copper alloy, which is stronger than pure nickel. There are two main grades of Monel washers which we produce, Monel 400 washers and Monel K500 washers. The Monel 400 has a high level of resistance to corrosion caused by hydrochloric acid, saltwater and hydrofluoric acid, hence it is suitable for hydrocarbon processes, chemical equipment and offshore. It is also characterised by high tensile strength and melts at approximately 1300°C.
Monel K500 is a low-chromium alloy that is a blend of toughness, hardness, and corrosion resistance; hence, it is used in surgical equipment, jewellery, and as a sealing material in industry. The quenching and tempering process of it boosts machinability, mechanical strength and resistance to pitting.
Our Monel washers pass rigorous tests such as mechanical, hardness, flattening and strength tests, which means that they are reliable in both hot and cold conditions. We shall also provide various packaging services like wooden boxes, cartons, bundles or plastic wraps to deliver safely.
Select Unifit Fasteners in high-quality Monel 400 and K500 washers that ensure durability, performance and precision in harsh industrial applications.
Request QuoteMonel washers are high-performance fasteners somewhat made of nickel-copper alloys (such as Monel 400 and K500) that are noted to be of exceptional strength, toughness, and great corrosion resistance, particularly in the marine, chemical processing, and aerospace sectors that fail with standard steel. They share the weight and offer safe fastening of the heavy conditions, offering dependability and durability.

Request QuoteMonel is widely used in industries that require high corrosion resistance, strength, and durability. It is commonly applied in marine and offshore equipment, chemical processing plants, oil and gas systems, heat exchangers, valves, pumps, and fasteners. Monel performs exceptionally well in saltwater, acidic, and high-temperature environments, making it ideal for demanding industrial applications.
Monel is considered better than stainless steel in highly corrosive environments, especially where saltwater, hydrofluoric acid, or alkaline solutions are present. While stainless steel is more cost-effective and suitable for general use, Monel offers superior corrosion resistance, higher strength at elevated temperatures, and longer service life in harsh conditions.
Monel and titanium serve different purposes. Monel provides excellent strength and corrosion resistance in marine and chemical environments at a lower cost than titanium. Titanium is lighter and offers superior resistance to certain chemicals but is significantly more expensive. For cost-effective, high-strength, and corrosion-resistant applications, Monel is often the preferred choice.
The primary metal in Monel is nickel, typically making up 60–70% of the alloy, with copper as the secondary element. Small amounts of iron, manganese, and silicon are added to enhance strength, corrosion resistance, and mechanical performance.
