Doshi Nickel Alloys

Generally, the maximum carbon content in 310 grade stainless steel is about 0.25%, but a low carbon variety, also known as Grade 310S, available in the market contains about a maximum of 0.08% carbon. Alloy 310S Fasteners are easily fabricated due to the lower carbon content in comparison to its alloy counterpart.

Monel K500 Fasteners are made of an alloy of nickel that combines the outstanding corrosion resistance and tensile strength of Monel 400. This nickel alloy is also known as Alloy K500. These different qualities of Monel K500 Fasteners are the product of an age-hardening process in which aluminium and titanium are added to a base of nickel and copper and then precipitated throughout the matrix. This process takes place over several years. This procedure results in nearly three times the yield strength of the K500 (110 ksi compared to 45 KSI) and approximately double the tensile strength of the 400 (160 ksi compared to 83 KSI) °F.

The Fasteners are ideal for use in environments where there is a presence of sour gas. Stronger than alloy 400, alloy K500 maintains this strength even when exposed to corrosive conditions. The only exception to this rule is that Fasteners made of Monel K500 may be more susceptible to stress corrosion cracking in specific environments than those made of Monel 400. In addition, seawater that is either not moving or moves very slowly can cause a disturbance, followed by cratering; however, the cratering rate typically slows down after the initial assault

Monel 400 Bolts and Nuts are made up of a nickel copper alloy that exhibits an extreme corrosion resistance, especially to acidic conditions. The material is also strong and hard and it is used to produce bolts and nuts that are applied for high temperature services. Navstar Steel is a leading manufacturer and supplier of the Monel 400 Bolts and Nuts in various dimensions and types. There are carbon, aluminum, manganese, silicon, iron, sulfur and 63% nickel and 28% copper in the composition. This composition brings the melting point of the material high.

Ti Gr2 heavy hex nuts are having very high impact toughness and are weldable readily.

The elements namely palladium, molybdenum, ruthenium, and nickel are added to Ti nuts for obtaining a good corrosion resistance ability especially in a little bit reducing atmosphere wherein titanium might face some issues because of insufficient condition for the formation of the essential protective oxide film onto the surface of the metal.

Hastelloy C276 Fasteners is a type of alloy fastener that is widely used in many industries due to its exceptional corrosion resistance properties. It is made from nickel-chromium-molybdenum and has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F. Hastelloy C276 Fasteners are also resistant to the formation of grain boundary precipitates in the weld heat-affected zone, making them suitable for most chemical process applications in welded conditions. Due to these outstanding characteristics, Hastelloy C276 Fasteners have become increasingly popular among manufacturers who need reliable fastening solutions with superior corrosion protection capabilities.

They are also aesthetically pleasing and robust fasteners, with high corrosion resistance. Aluminium is not magnetic, so is ideal for use in electronics and sensitive applications.
Aluminum screws and fixings are available from stock, or on short lead times

Copper Nickel 70/30 Fasteners are made up of a material composition of 88.6% copper, lead, manganese, iron, zinc and 9% nickel in the composition. Micro Metals is a leading manufacturer and supplier of the Cupro Nickel 70/30 Bolts And Nuts in various dimensions and standards. The material has good strength and mechanical properties.

The minimum yield strength of the material is 241MPa and the minimum tensile strength is 551MPa with the elongation rate of 30%. The material is also heavy with 8.1 grams per centimeter cube of density. The UNS C71500 Hex bolts are made under a specification ASME SB 151 or SB 152. The length of the fasteners varies up to 5 meters with the sizes ranging from M4 to M100. The WNR 2.9882 Studs and other fasteners could be hot forged or cold forged. There are different types of fasteners such as nuts, bolts, screws, sockets, hex set screws and so on.

Each different type of the fasteners have different application purposes and are used in different industrial application set ups. Most applications include chemical, petroleum, oil and gas, refinery and other high corrosive condition applications. One of the prominent uses is seen in the marine and sea water applications.
