Steel Fasteners

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.

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

2205 Duplex nuts are the most widely used duplex stainless steel 2205 fasteners and feature a high yield strength that is twice that of standard austenitic stainless grades.

Duplex 2205 nuts and nuts are widely used in applications requiring good corrosion resistance and strength in marine and harsh environmenuts.

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.

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

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.

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.

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.

ASTM A194 bolts include metals such as manganese and silicon, with additions of phosphorus, sulfur, and carbon. ASTM A194 gr 2h bolts are suitable for high pressure or high temperature service, or both. Further machining is possible by centerless grinding or cold drawing.

ASTM A193 Grade B7 Heavy Duty Hex Head Bolts are high strength fasteners made from heat treated alloy steel AISI 4140/4142 quenched and tempered.

The ASTM A320 specification, originally approved in 1948, covers alloy steel and stainless steel bolting materials for low temperature service.

A193 B7 Cadmium Plated stud bolts are made of alloy steel for high temperature environments. ASTM standards cover alloy steel and stainless steel bolting materials; this specification covers fasteners for pressure vessels, valves, flanges, and fittings.
