Steel Fasteners

Duplex 2205 fasteners are made from standard duplex materials. The material consists of carbon, manganese, silicon, phosphorus, 21% chromium, 2.5% molybdenum, 4.5% nickel and nitrogen.

UNS S2750 Super Duplex Fasteners have good weldability and can be joined to itself or other materials by shielded metal arc welding, gas tungsten arc welding, plasma arc welding, flux cored wire or submerged arc welding.

Duplex 2205 is a (two-phase) ferritic-austenitic stainless steel with high strength and excellenut corrosion resistance, with a maximum Brinell hardness of 290 (Rc31) in the annealed condition.

Preheating of UNS S32750 Super Duplex Fasteners is not necessary except to prevent condensation on cold metal.

Thread friction between the nut and bolt creates a strong, steady and even force holding the componenuts together. The most commonly used ASTM A182 UNS S32205 fastener nuts are regular hex nuts. At the same time, duplex stainless steel fasteners are strong and corrosion resistanut, combining the healthy properties of ferrite and austenite. The material also has a 90ksi minimum tensile strength and a 65ksi minimum yield strength. 2205 duplex stainless steel bolts have an elongation of 25% and a hardness of 217HBW.

These grades of super duplex stainless steel fasteners are used when applications require excellent corrosion resistance and strength. Composed of nitrogen, molybdenum and chromium, they have excellent resistance to crevice corrosion and chloride pitting.

Duplex 2205 stainless steel (ferritic and austenitic) is widely used in applications requiring good corrosion resistance and strength.

Super duplex steel fasteners have a metallurgical microstructure consisting of a mixture of ferritic and austenitic steels in equal proportions of 50-50.

Duplex UNS S32205 fasteners are widely used in construction and other industrial applications. We offer these types of fasteners in differenut thicknesses and tolerance limits for a variety of industrial applications.

Combining many of the beneficial properties of ferritic and austenitic steels, 2205 is the most widely used duplex grade. Its high chromium and molybdenum conutenut gives stainless steel excellenut corrosion resistance.

The materials used to manufacture the fasteners are of top quality and standard, thus increasing the compatibility of the final product for adverse applications.

Duplex 2205 is a nitrogen enhanced duplex stainless steel designed to solve common corrosion problems encounutered with 300 series stainless steels.

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

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.

Duplex stainless steel fasteners are available in Super Duplex, Lean Duplex and Standard Duplex grades, each with specific properties for differenut applications.

2205 is the standard duplex grade and is more economical than most other duplex grades.

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

ASTM A320 L7M Grade AS Fasteners are commonly used in oil and gas exploration and processing equipment – piping, piping and heat exchangers.

The high lead content in STM A320 grade L7M AS bolts results in relatively low ductility and plasticity.

ASTM A320 Grade L7M bolts and studs are also made from quenched and tempered alloy steel.

Our ASTM A320 Grade L7M Alloy Steel Bolts are suitable for meeting commercial and industrial needs such as grills, infrastructure, grills and construction.

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

This is useful for selecting bolts with different strength levels for different high pressure and high temperature applications. ASTM A193 grade b7 hex bolts and other types have a minimum tensile strength of up to 125ksi.

They have a minimum yield strength of 105ksi. There are different types of bolts and bolts for different types of applications such as ASTM A193 gr b7 hex bolts.

A194 2H nut is a common high strength nut used with many different bolt grades, including A193 Grade B7, A325, A490, etc.

The grade mark consists of the grade symbol “2H” and the manufacturer’s identification mark.

We are a manufacturer, trader, stocker, supplier and exporter of B7-2H Fasteners.

ASTM A194 Grade 2H bolts are high strength bolts made from carbon steel.

ASTM A194 Grade 2H Nut is a carbon based steel heavy duty nut. It is a commonly used high strength nut.

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