Alloy 20 Fasteners Supplier

Alloy 20 Fasteners, or Carpenter 20 or “20Cb-3”, are corrosion-resistant fasteners made from nickel, chromium, and iron alloys. This type of fastener is popular for use in the chemical industry due to its superior corrosion resistance and strength. There are several types of Alloy 20 Stainless Steel Fasteners available. The most common type is a hex head bolt used in various applications such as construction and automotive. Hex head bolts can be found in standard sizes ranging from 1/4 to 2 inches. U-bolts are typically used in plumbing applications and have a larger diameter than hexhead bolts. Other types include carriage bolts, lag screws, eye bolts, and threaded rods.

Alloy 20 Fasteners are primarily used in industrial applications such as petrochemical plants, pharmaceutical plants, and oil refineries due to their superior corrosion resistance and strength. These types of fasteners are often used in high-temperature environments where other materials may not be able to withstand heat or pressure. They are also commonly used for marine applications since they can resist saltwater corrosion better than other materials. We offer various kinds of Fasteners like Monel 400 Fasteners, SMO 254 Fasteners, etc.

The primary benefit of astm b473 alloy 20 Fastener is that they offer superior corrosion resistance compared to other materials, such as stainless steel or carbon steel. That makes them ideal for use in corrosive environments such as chemical plants or areas near salt water where other materials may not last long enough before needing replacement. They also have good mechanical properties, so they can handle higher temperatures than other materials without becoming brittle or weak. These fasteners don’t require special plating or coating so they can be installed quickly with minimal effort. 

Alloy 20 Fasteners offer many advantages over other types of material regarding strength, durability, and corrosion resistance. They are most commonly used in industrial applications where corrosive elements or high temperatures may be present. Still, they can also be useful for marine applications because they can resist saltwater corrosion better than other materials.

What are Hastelloy C276 Fasteners?

Alloy 20 Fasteners are commonly used in industries such as chemical processing, pharmaceuticals, food processing & power generation.

How do Alloy 20 Fasteners hold up in high-temperature environments?

Alloy 20 Fasteners have good resistance to high-temperature environments up to 1000°F (537°C) and retain their strength and toughness even at elevated temperatures.

Can Alloy 20 Fasteners be customized for specific applications?

Yes, Alloy 20 Fasteners can be customized for specific applications with varying sizes, dimensions & coatings to suit the requirements.
