Product Description

Super Duplex Fasteners ISO4017 S32205 2205 Duplex Steel Hex Bolt Nut Washer

1. Product Overview
The product made from premium super duplex stainless steel UNS S3205 ( ASTM A182 F60), these full-thread stud bolts follow global industrial standards including ISO4017, serving as core fastening spare parts for high-pressure & heavy-corrosion industrial piping, pressure vessel flange connections.

Standard	Component	Description & Key Details
ISO 4017	Hexagon Head Screws (fully threaded)	A bolt or screw with a hexagon head, fully threaded from under the head to the end.
ISO 898-1	Mechanical Properties (for bolts/screws)	Defines strength grades (Property Classes) for carbon/alloy steel bolts/screws. For Duplex 2205, not a direct strength grade match, but provides the framework.
ISO 4032	Hexagon Nuts (Style 1)	Specifies "regular" hexagon nuts with metric coarse threads.
ISO 7089	Plain Washers (Normal Series)	Defines standard plain washers (replacing the older DIN 125 standard).

What This Means as a Complete Assembly

This combination of standards indicates a complete bolted joint designed for demanding applications:

The Bolt: An ISO 4017 fully-threaded hexagon head screw. If it's made of Duplex 2205, it will have the characteristic high strength and corrosion resistance of that material.
The Nut: An ISO 4032 hex nut, also made from Duplex 2205 to match the bolt's material and performance. Some manufacturers may use ISO 898-2 to specify nut property classes, ensuring compatibility with the bolt's strength.
The Washer: An ISO 7089 flat washer. When made of Duplex 2205, it provides a load-bearing surface that won't corrode or fail in aggressive environments.

Important Note on ISO 898-1 and Duplex 2205:While ISO 898-1 is commonly used for carbon and alloy steel fasteners,it does not define property classes for stainless steels like Duplex 2205. For stainless steel, the mechanical properties are typically governed by standards like ISO 3506. Therefore, a "2205 fastener" specified with ISO 898-1 likely uses the standard for its dimensional and general testing framework, while the material-specific Duplex 2205 properties (like its ~620 MPa tensile strength) are guaranteed by the material specification itself, often under UNS S32205 or S31803.
