Alloy 20 Forgings Manufacturer, Supplier

Robust Special Metals, based in Mumbai – India, needs no introduction. For many years, we have been one of the leading and most well-established suppliers, manufacturers, and exporters of Alloy 20 forging. With our expertise and commitment to quality, we are a trusted source in the industry.

Alloy 20, also known as Carpenter 20, is a type of superalloy developed primarily for harsh and corrosive applications. DIN 2.4660 chemical composition includes a mixture of nickel, chromium, and molybdenum, with small amounts of copper and iron. Compared to other stainless steels, it also has excellent mechanical properties, such as high tensile and yield strength, excellent corrosion resistance, good toughness, and superior resistance to stress corrosion cracking and pitting.

Alloy 20 Forging

Alloy 20 forging is widely used in multiple industries because of its remarkable strength and high corrosion resistance. To achieve ideal toughness and ductility, the optimal forging temperature for this alloy is between 2100 and 2250 degrees Fahrenheit. When machining Alloy 20, special tooling may be necessary due to its tendency to work harden. However, this alloy is weldable using techniques like TIG welding. It can be heat treated to enhance its mechanical properties, making it a versatile material for equipment such as valves, pumps, and heat exchangers.

Let's see why alloy 20 is best suited for forging.

Alloy 20 is an ideal alloy for forging due to various reasons. Firstly, it displays remarkable hot workability, making it easy to shape and deform during the forging process. Secondly, its good thermal stability enables it to withstand the high temperatures required for forging without compromising its structural integrity. Lastly, it’s excellent corrosion resistance and high mechanical strength make it a dependable option for forged components in challenging environments.


Chemical Processing

Alloy 20 forgings offer excellent acid corrosion resistance, making them ideal for chemical processing applications and environments with crevice corrosion and pitting.

Pollution Control

With resistance to sulfuric acid and high temperature endurance, Alloy 20 forgings are perfect for flue gas scrubbers and other pollution control equipment.

Oil and Gas Production

Resistant to sulphurous gases and chloride stress corrosion cracking, Alloy 20 forgings suit sour gas wells and offshore oil and gas platforms.

Nuclear Power

Alloy 20 forgings withstand radiation damage and chloride stress corrosion cracking, making them suitable for nuclear reactors.


Ideal for desalination plants, Alloy 20 forgings resist chloride stress corrosion cracking, pitting, and crevice corrosion.

At Robust Special Metals, we care for our customers and provide them with different Alloy 20 products to fulfil their project’s needs and requirements. We provide the best products and excellent customer service; hence, we have clients all over the globe.
