Alloy 330 Nuts

Alloy 330 (1.4864) nuts are specifically designed for high temperature furnace applications such as vacuum furnaces, heat treating and brazing applications. The most prized trait of alloy 330 is its ability perform under cyclic conditions of temperature extremes from heating and cooling; as well as in alternate carburizing and oxidizing atmospheres. An austenitic, nickel-chromium-iron-silicon alloy, 330 nuts also offer industry a low coefficient of expansion, excellent ductility, and high strength.

Alloy 20 Nuts

Also known as Carpenter 20 and 20CB-3, Alloy 20 nuts offer users a combination of nickel, chromium, molybdenum, and copper which provides good general corrosion resistance. Alloy 20 (2.4660) nuts are best suited for mid-range corrosion use – better than steel alloys but not at the level of high performance nickel based alloys like Hastelloy C276. Alloy 20 is a nickel alloy that was specifically designed to withstand the harsh environment of hot sulfuric acid but also performs well in a variety of other acids. Alloy 20 nuts are an ideal choice when you don’t need the corrosion resistance power and price-tag of high performance nickel alloys like Hastelloy C276; but you need something that will give you more protection than 316 stainless steel or even a Super Duplex 2507 stainless steel.

A286 Nuts

A286 (1.4980) nuts, also known as Alloy 660 nuts are stainless steel alloy which contains iron, nickel and chromium. A286 nuts are known for their high strength, creep resistance and oxidation resistance at elevated temperatures once age hardened.  As a result, A286 / Alloy 660 nuts provide high levels of strength from room temperature up to about 1300°F (700°C).
A286 nuts are also mildly corrosion resistant. While they should not be used for strong acid environments, they provide excellent oxidation resistance up to 1500°F (815°C) in conditions that would typically be found in high temperature exhaust streams.

AL6XN Nuts

Originally developed to combat sea water corrosion, AL6XN has expanded its role as being good mid-range corrosion resistant alloy. AL6XN nuts are a low carbon, high purity, nitrogen-bearing "super-austenitic" stainless alloy. Also considered a 6Moly alloy, AL6XN nuts are similar in chemistry and capabilities to Alloy 926 and SMO 254. With a higher nickel and molybdenum content than Duplex 2205 and Super Duplex 2507, it delivers better corrosion resistance while giving a more cost effective alternative to nickel super alloys like Inconel or Hastelloy in moderately corrosive conditions.

17-4 PH Nuts

17-4 PH nuts are made from a precipitation hardened stainless steel most known for its exceptional strength and its ability to maintain its mechanical properties to 600°F. Compared to 316 stainless steel, 17-4 PH nuts yield strength is up over 4 times greater. When compared to Duplex 2205 nuts, the yield strength of 17-4 PH can be up to 2-½ times greater.
17-4 nuts are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties

Tantalum Screws

Tantalum screws are best known for its unmatched corrosion resistance and chemical inertness. Tantalum screws have a similar corrosion resistance to that of glass, but all of the typical mechanical and electrical properties of a metal.
Tantalum screws are also extremely stable at high temperatures, since tantalum has a melting point around 3000°C. High temperature applications require vaccum or inert gas since tantalum may embrittle when used in oxygen rich environments above 250°C.  Tantalum screws are also one of the most bio-compatible metals available and is also radio-opaque due to its high density (16.68 g/cm3).
All tantalum screws are available in commercially pure tantalum and tantalum 2.5% tungsten (Ta-2.5%W).

MP35N Screws

MP35N (2.4999) screws are known for their extraordinary strength and are the strongest screws we offer at RAYCHIN. MP35N screws owe their extraordinary strength to a unique alloy combination of nickel, cobalt, chrome and molybdenum and have ultimate tensile strengths that range from 227 ksi to 294 ksi (with age hardening).
Beyond the strength of MP35N screws, they are also exhibit good corrosion resistance and can resist most mineral acids, hydrogen sulfide, seawater and salt spray environments.
MP35N screws are also resistant to high temperature oxidation and could operate in environments up to 800°F and still maintain much of its strength.

Inconel Screws

Inconel® screws, like Inconel 600, 601,625,686,718 & 725 screws, are a family of nickel-chromium-molybdenum alloys used for their high strength at elevated temperatures and good corrosion resistance. Because of its high thermal stability, Inconel can be used in service temperatures ranging from cryogenic to 2200°F (982°C). The high alloy content of Inconel screws enable it to withstand a wide variety of severe corrosive environments. In mild environments, such as the atmosphere, sea water, neutral salts, and alkaline media, there is almost no attack to Inconel screws. In more severe corrosive environments the combination of nickel and chromium provides resistance to oxidizing chemicals, whereas the high nickel and molybdenum contents supply resistance to nonoxidizing environments.
