Additionally, Duplex 2205 is the most widely used duplex grade on the market. Duplex 2205 alloy is a nitrogen-enhanced duplex stainless steel alloy. The effect of nitrogen is to significantly increase the corrosion resistance of the alloy; especially in the as-welded condition.

Super Duplex 2507 stud bolts (EN 1.4410) are made of a stainless steel alloy containing 25% chromium, 4% molybdenum, and 7% nickel. Duplex 2507 is known for its high strength and excellent localized corrosion resistance to chloride.

Alloy-20 is a “super” stainless steel designed for excellent resistance to acid attack. Its nickel, chromium, molybdenum and copper content contributes to its overall resistance to chloride stress corrosion cracking and general pitting attack. It is virtually immune to chloride stress corrosion cracking. It is often found in chemical mixers and fertilizer manufacturing equipment. In general, it is an economical alternative to alloy C276 and other materials with a higher nickel content.

316 stainless steel bolts are made of corrosion-resistant and strong austenitic stainless steel. The material is composed of chromium, nickel, molybdenum and other elements. This provides a high yield strength of 205MPa and a minimum tensile strength of up to 515MPa for 316 stainless steel bolts and nuts.

Inconel 625 is a nickel-chromium-molybdenum alloy with added niobium that works with molybdenum to strengthen the alloy’s matrix for excellent strength and toughness.

Monel alloys are a group of alloys consisting mainly of nickel and copper with trace amounts of iron, manganese, carbon and silicon. ASTM B865-04 K500 Monel Fastener is a precipitation-hardening nickel-copper alloy. One of the advantages of using alloy UNS N05500 bolts is that the alloy combines the excellent corrosion resistance of Monel 400 alloy with the additional properties of increased tensile strength and hardness.

Stainless steel washers are more corrosion resistant than steel washers and are almost as strong. 18 – 8 and 17 – 7 PH stainless steel gaskets can be used in wet, wet and washdown environments, but will corrode if exposed to salt water or chemicals.

ASTM A1082 specification alloy S31803 fasteners have higher pitting and crevice corrosion than stainless steel alloy 316. Due to its higher corrosion resistance, alloy grade UNS S31803 is able to exhibit better fatigue strength than other commonly used austenitic stainless steel grades in environments containing corrosive media.

The alloy is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

It is resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy 200 and 201 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions.

UNS S32205 nuts (also known as S31803) are manufactured from high-grade duplex 2205 stainless steel. Since this material is composed of at least 22% chromium, 6% nickel and 3% molybdenum it can withstand several unique types of environmental inflexibilities that other metals cannot such as corrosion, cracking, erosion, pitting and more. Super duplex stainless steel 2205 nuts also provide twice the mechanical strength compared to standard stainless steel.

Bolts made from Alloy 926 are a super austenitic molybdenum stainless steel with comparable corrosion resistance to Super Duplex 2507, but with slightly lower strength and cost. Chemically nearly identical to 6-molybdenum alloys AL6XN and SMO 254, alloy 926 is commonly used in paper mills, desalination and mild acid environments.

A193 B7 threaded rods are also known as hex bolts. It has threads on both ends and it is a relatively long rod.

Zeron 100?contains 25% chromium and 7% nickel and 3.6% molybdenum along with copper and tungsten additions. Zeron 100 has a 50¨C50 austenitic¨Cferritic structure. It also has greater resistance to chloride pitting, crevice corrosion and stress corrosion cracking than exhibited by the standard 300 series stainless steels.

UNS S31803 Bolt is a threaded fastener with external threads. Generally, like screws, alloy S31803 bolts tend to use a variety of head designs.

Inconel 625 locknuts are known for their tight tolerances and precise dimensions. Inconel 625 nylon nut is a nickel-based superalloy with high strength properties and high temperature resistance.

Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. This grade offers higher resistance to corrosion

Duplex 2205 alloy is composed of high chromium and low or moderate nickel conutenut.

In addition to good corrosion resistance and high tensile strength, Duplex 2205 Hex Bolts also have high surface toughness. This and the passive oxide layer formed by the addition of chromium is the reason why 2205 duplex stainless steel fasteners are used in the marine industry.

High carbon steel bolts have a carbon content between 0.60 – 1.25%. High carbon steel alloys have manganese content in the range of 0.30 – 0.90%. Of all three grades, high carbon steel threaded rod has the highest hardness and toughness while exhibiting the lowest ductility. The high wear resistance comes from the fact that these screws are almost always hardened and tempered.

Offering the industry an improved stainless steel corrosion solution, Duplex 2205 Bolts have good sulfide corrosion resistance, as well as chloride pitting and crevice corrosion superior to 317L. The combination of chromium, molybdenum and nitrogen provides Duplex 2205 bolts with good chloride pitting and crevice corrosion protection, which makes them useful in marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.

ASTM A193 B7 is a chromium molybdenum alloy steel. B7 achieves its strength through a heat treatment process that is quenched and tempered at 1150 degrees Fahrenheit.

The ASTM A194 specification covers carbon, alloy and stainless steel bolts for high pressure and/or high temperature service.

Also known as Alloy 625, Inconel 625 hex bolts are known for their ability to retain their strength and resist heat ¨C both in and out of corrosive environments. The presence of nickel and chromium make Inconel 625 hex bolts corrosion, oxidation and carburization resistant. The molybdenum delivers excellent fatigue strength and resistance to stress, pitting and crevice corrosion cracking even when exposed to chloride ions.
