Alloy 20 Bolts

What are Alloy 20 Bolts?

Alloy 20 bolts are made from an alloy containing nickel, chromium, molybdenum, copper and iron. This combination of metals makes them resistant to corrosion from a wide range of acids and chemicals. The high strength and durability makes Alloy 20 Bolts perfect for applications where strength is necessary but corrosion resistance is paramount.

UNS N08020 Bolts can be used in many different industries, including oil & gas exploration & production, chemical processing plants, water treatment plants, waste treatment plants, food processing operations, nuclear power stations and marine vessels. These fasteners can also be found in medical equipment as well as pumps and compressors. Alloy 20 Bolts have good tensile strength up to 1120MPa which makes them suitable for use in high stress applications such as petrochemical refineries and marine vessels. Finally, they offer superior thermal stability over other alloys making them ideal for use in extreme temperature environments such as power plants or nuclear facilities. There are several products available like 1.4980 Stud Bolts, 1.4980 Heavy Hex Nuts, etc.

The most significant benefit of using Alloy 20 Bolts is their ability to resist corrosion from a variety of acids and chemicals due to their composition – nickel-chromium-molybdenum-copper-iron alloys provide excellent protection against both general corrosion as well as pitting caused by chlorides.

Alloy 20 Bolts offer superior resistance to corrosion compared to other metals, including stainless steel. The alloy contains chromium, nickel, and molybdenum which makes it resistant to acids and caustic materials. This means that the bolts can be used in harsh environments where conventional steel would not be suitable—such as in chemical processing plants or in marine environments.

In addition to their excellent corrosion resistance, ASTM B472 UNS N08020 Bolts also have a high level of durability due to their strong tensile strength. This means that they can withstand significant amounts of wear and tear without breaking or becoming weakened over time. This makes them ideal for applications such as heavy-duty construction projects or industries that require long-term use of the same bolts.

Alloy 20 bolts are more cost-effective than traditional steel bolts because they require less maintenance and last longer than other metals. This is due to their high level of corrosion resistance and superior durability, which means that they need fewer repairs or replacements over time.

Types of Alloy 20 Bolts

There are two main types of alloy 20 bolts – hex head cap screws and socket head cap screws. Hex head cap screws have a hexagonal head that fits into a corresponding socket or wrench while socket head cap screws have an internal hexagonal recess which allows them to be tightened or loosened using an appropriate tool such as an Allen key or spanner wrench. Both types are available in metric sizes ranging from M5 (5mm) to M20 (20mm).

What are Alloy 20 Bolts?

Alloy 20 Bolts are high-performance fasteners made from a nickel-chromium-molybdenum alloy known as Carpenter 20 or UNS N08020. These bolts are designed to offer excellent corrosion resistance, mechanical strength, & durability in a range of harsh environments.

What are the benefits of using Alloy 20 Bolts?

The benefits of using Alloy 20 Bolts include excellent resistance to corrosion, pitting, & crevice corrosion in acidic & chloride-containing environments. Alloy 20 bolts are also highly resistant to stress corrosion cracking & have excellent mechanical properties, making them ideal for use in harsh industrial environments.

What are the applications of Alloy 20 Bolts?

Alloy 20 Bolts are widely used in applications that require high corrosion resistance, such as in chemical processing, pharmaceutical, & food processing industries. Alloy 20 bolts are also used in marine & offshore applications, heat exchangers, & other harsh environments.
