Stainless steel 235MA fasteners are mass produced in strong specialty metals. Stainless steel is a metal that is in high demand in all industries. The metal is very strong and durable, proving its usefulness. 253 ma fasteners are made with high quality raw materials from reputable factories. Proper oversight from a team of experts will help effectively ensure that the 253 ma fasteners meet all your desired applications.

ASTM A193 Grade B7 specification covers the requirements for high strength alloy steel bolting materials for high temperature or high pressure service and other special purpose applications. It is a standard specification that defines typical chemical composition, mechanical properties, hardness requirements, preferential heat treatment, product marking, certification, and other requirements for bolted connections used in pressure vessel service, valves, flanges, and fittings. ASTM A193 defines SI (metric) and inch-pound units.

ASTM A320 L7 Stud Bolts are designed for low temperature performance. These fasteners are commonly used in valves, flanges, fittings and pressure vessels. The ASTM specification recommends a minimum impact value of 20-ft-lbf -150F for ASTM A320 L7 studs.

Inconel 718 is a high strength, corrosion resistant nickel-chromium material that can be used in temperatures from -423¡ã to 1300¡ãF. Inconel 718 age hardening alloy can be easily fabricated, even into complex parts. The welding characteristics of Inconel 718, especially its resistance to post-weld cracking, are excellent.

Duplex 2205 stainless steel (ferritic and austenitic) is widely used in applications requiring good corrosion resistance and strength. Grade S31803 stainless steel was modified several times, resulting in UNS S32205, which was recognized in 1996. This grade provides higher corrosion resistance If we do not stock Duplex 2205 fasteners (imperial or metric), we can manufacture these to your specifications.

Welding of this alloy is similar to that of the C-22 alloy. Gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) are commonly used to weld C-276 alloys.

It is recommended that the alloy be welded in the solution annealed condition with C-276 filler metal.

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.

Duplex nuts S31803 also have good fatigue and corrosion resistance in most environmenutal conditions.

As an austenitic and nickel-based alloy, Alloy 926 nuts are ductile over a wide temperature range from low temperatures to over 1000 degrees Fahrenheit (538 degrees Celsius). Machinability is typical of nickel-based alloys, with alloy 926 bolts that can be easily welded and formed using a variety of techniques.

The high molybdenum content imparts resistance to localized corrosion such as pitting.

The alloy 20 stainless steel flat washer has a plain finish. The flat washer provides a bearing surface for fastener load distribution or is used as a spacer between components. Alloy 20 stainless steel is strong and provides better corrosion resistance in aggressive chemical environments than 316 stainless steel. The material may be slightly magnetic.

Inconel 718 is a molybdenum, chromium and nickel based alloy developed to resist a wide range of severely corrosive atmospheres, crevice corrosion and pitting corrosion.

INCONEL alloy C-276 is designated as UNS N10276 and Werkstoff Nr. 2.4819. It is listed in NACE MR0175 for oil and gas service.

Fasteners vary in size, shape, grade and specification. The most commonly used fasteners are bolts and nuts. Carbon steel washers are also commonly used to tightly mate nuts with bolt heads and mating surfaces.

UNS S32750 or DIN W.Nr. 1.4410, Duplex 2507 is a super duplex stainless steel conutaining 25% chromium, 4% molybdenum and 7% nickel, designed for demanding applications requiring exceptional strength and corrosion resistance, such as chemical Process, petrochemical and seawater equipmenut.

Inconel 625 bolts can be used in a variety of corrosive environments due to their ability to prevent stress corrosion, crevice corrosion and pitting corrosion. In mild applications such as atmospheric, fresh or salt water, neutral salts and alkaline media are almost completely tolerated. In more severe cases, nickel and chromium content provides resistance to oxidizing chemicals. Inconel 625 bolts are also resistant to non-oxidizing environments.

A194 2H Heavy Duty Hex bolts are designed for high strength, high temperature or high pressure applications and are usually available in a plain finish.

All our stainless steel bolts and nuts have no minimum order quantities, you can order as little as one bolt or nut. If you still can’t find what you are looking for, please contact us.

Inconel 600 Bolts can also be easily formed, machined and welded. The minimum tensile strength of fasteners can reach 825MPa, and the minimum yield strength can reach 620MPa. The strongest are cold-worked round fasteners.

Since Inconel uses nickel as its primary alloying agent, the use of Inconel 718 fasteners at elevated temperatures has no negative effect on the application or the equipment being used.

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

ASTM A193 Grade B7M bolts and studs have the same chemical composition as Grade B7 (quenched and tempered medium carbon alloy steel) but have lower strength requirements requiring 100% hardness testing on all fasteners manufactured in the batch. Grade B7M bolts are resistant to chloride, sulfide and hydrogen stress corrosion cracking (SCC) and are often used in sour gas service.

Hastelloy X is extremely resistant to stress corrosion cracking in petrochemical applications. All product forms are excellent in forming and welding.

2205 dual-phase steel fasteners have some excellenut mechanical properties, which may be due to the balanced austenitic and ferritic microstructures in the alloy.

ASTM A479 Duplex Steel UNS S32205 Spring Washers have excellent weldability and can be joined by most common welding methods such as metal arc welding, plasma arc welding, submerged arc welding and gas tungsten arc welding. ASME SA 479 Duplex Steel UNS S31803 Square Washer is a ferritic, austenitic 22% chromium, two phase, 3% molybdenum and 5-6% nickel alloy steel.

Hastelloy Nickel Alloy B2 is a very chemically resistant alloy with high resistance to pitting and stress corrosion cracking in the heat affected zone.

Inconel 600 Bolts are composed of Chromium, Nickel and Molybdenum. This makes these bolts superior to stainless and carbon steel bolts. The lengths of these bolts are between 3mm and 200mm. Inconel 600 Hex Bolts are highly resistant to corrosion and oxidation. These bolts are designed to handle extreme temperatures and high pressures.
