Alloy 20 Fasteners Manufacturer

Global Steel is a leading manufacturer and supplier of Alloy 20 Fasteners. It provides a comprehensive range of Alloy 20 Fasteners, all of which are manufactured in accordance with globally recognized standards. Because of our extensive expertise and experience in this business, we are able to sell our products at a reasonable price range as one of India’s most renowned stockists of Alloy 20 fasteners.

Alloy 20 Fasteners belong to the austenitic type and have elements like nickel, chromium, and iron in their composition. These Alloy 20 fasteners have great corrosion resistance ability. It is a niobium stabilized grade and is highly resistant to reducing conditions containing rough chemicals like sulfuric acid. This alloy 20 fastener is highly resistant to inter-granular attacks at elevated temperatures.

Our fasteners are reliable for any corrosive or acidic environments such as nitric, phosphoric, and aqueous salt solutions. Alloy 20 fasteners are a perfect solution for chloride containing environment as they offer exceptional resistance to stress corrosion and pitting. These fasteners are highly resistant to crevice corrosion and aqueous corrosion.

Due to outstanding mechanical properties and chemical composition, these fasteners can easily withstand elevated temperatures and pressure applications. These fasteners have great formability and welding ability. We manufacture these fasteners in standard as well as custom-made specifications. These fasteners go through several tests to ensure that our clients get products made of good quality. These fasteners are highly durable, robust, dimensionally precise, and anti-corrosive.

These Alloy 20 fasteners have amazing features and are used in a variety of industries and industrial applications. Some of the industries that these fasteners are used in are the power generation industry, chemical processing, oil and gas industry, and many more.

What is the difference between Alloy 20 and 316 stainless steel Fasteners?

Alloy 20 and 316 stainless steel fasteners differ in their composition and properties. Alloy 20 contains more nickel, chromium, and molybdenum than 316 stainless steel, making it more resistant to corrosion, especially in acidic environments. It is also stronger and more durable than 316 stainless steel. 316 stainless steel, on the other hand, is a general-purpose, cost-effective alloy that is widely used for its corrosion resistance and good mechanical properties. The choice between the two depends on the specific application and environmental conditions.

What is the hardness of Alloy 20 fasteners?

The hardness of Alloy 20 fasteners can vary depending on the specific type of fastener and its manufacturing process. Generally, the alloy has a maximum hardness of around 217 Brinell hardness (HB) in the annealed condition, which can increase to a maximum of 96 HRB (Rockwell B hardness) in the cold-worked condition. However, the exact hardness of Alloy 20 fasteners depends on the application’s specific requirements and the manufacturing process used.

What is the maximum temperature limit for Alloy 20 Fasteners?

Alloy 20 fasteners have a maximum recommended temperature limit of around 925°C (1700°F). Operating above this temperature may lead to a reduction in mechanical properties, including strength & toughness. It is crucial to consider the specific temperature requirements and consult the manufacturer’s specifications for the appropriate selection of Alloy 20 fasteners.
