This document specifies the mechanical and physical properties of bolts, screws and studs, with
coarse pitch thread and fine pitch thread, made of corrosion-resistant stainless steels, when tested at
the ambient temperature range of 10 °C to 35 °C. It specifies property classes in relation to austenitic,
martensitic, ferritic and duplex (austenitic-ferritic) steel grades for fasteners.
The term “fasteners” is used in this document when bolts, screws and studs are considered all together.
ISO 3506-6 provides general rules and additional technical information on suitable stainless steels and
their properties.
Fasteners conforming to the requirements of this document are evaluated at the ambient temperature
specified in paragraph 1. It is possible that they do not retain the specified mechanical and physical
properties at elevated and/or lower temperatures.
NOTE 1 Fasteners conforming to the requirements of this document are used without restriction in
applications ranging from –20 °C to +150 °C; however, fasteners conforming to this document are also used for
applications outside this range down to –196 °C and up to +300 °C. For more details, see Annex A and ISO 3506-6.
Outside the temperature range of –20 °C to +150 °C, it is the responsibility of the user to determine the
appropriate choice for a given application in consultation with an experienced fastener metallurgist
and by taking into account e.g. stainless steel composition, duration of exposure at elevated or low
temperature, the effect of the temperature on the fasteners mechanical properties and clamped parts,
and the corrosive service environment of the bolted joint.
NOTE 2 ISO 3506-5 is developed in order to assist in the selection of appropriate stainless steel grades and
property classes intended for use at temperatures up to +800 °C.
This document applies to bolts, screws and studs:
— with ISO metric thread in accordance with ISO 68-1,
— with diameter/pitch combinations in accordance with ISO 261 and ISO 262,
— with coarse pitch thread M1,6 to M39, and fine pitch thread M8×1 to M39×3,
— with thread tolerances in accordance with ISO 965-1 and ISO 965-2,
— with specified property classes, and
— of any shape.
Stainless steel grades and property classes can be used for sizes outside the diameter limits of this
document (i.e. for d < 1,6 mm or d > 39 mm), provided that all applicable chemical, mechanical and
physical requirements are met.
Certain bolts, screws and studs might not fulfil the tensile or torsional requirements of this document
because of the geometry of their head or unthreaded shank, thus resulting in reduced loadability (e.g.
when shear area in the head is less than the stress area in the thread; see 8.2.2).
This document does not apply to set screws and similar threaded fasteners not under tensile stress
(see ISO 3506-3).
It does not specify requirements for functional properties such as:
— torque/clamp force properties,
— shear strength,
— fatigue resistance, or
— weldability.

The material standards for steel bars and wire rod can exclude the application of one or other of the surface quality classes of this document. They can also cover requirements for surface quality which deviate from this document. In these cases the requirements of the material standard prevail.

This document specifies requirements for the following grades of wrought tool steels:
a) non-alloy cold-work tool steels;
b) alloy cold-work tool steels;
c) alloy hot-work tool steels;
d) high-speed tool steels.
If not stated otherwise, this document applies to all types of hot-rolled, forged, cold-drawn or cold-rolled products or products produced by powder metallurgy, which are supplied in one of the surface and heat-treatment conditions given in 6.2 and Table 1.
NOTE Tables 2, 4, 6 and 8 cover only those steels which have gained certain international importance, which does not mean, however, that they are available in all industrial countries. In addition, a number of other steels for tools are specified in regional, national or company standards.
Where the heat resistance of the tools is of particular importance, as for example in the case of tools for hot forming glass, the material selection is based on ISO 4955.

ISO 683-4:2016 gives the technical delivery requirements for semi-finished products (e.g. blooms, billets, slabs), bars and wire rod, manufactured from the free-cutting steels listed in Table 2 and supplied in one of the treatment conditions given for the different types of products in Table 1, rows 2 to 4.
It covers three groups of free-cutting steels for mechanical purposes as listed in Table 2, namely
a) not intended for heat treatment,
b) suitable for case-hardening, and
c) suitable for quenching and tempering.
Free-cutting steels are often used as bright bars. For these products, refer to ISO 683‑18.
In special cases, variations in these technical delivery requirements or additions to them can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex B).
In addition to ISO 683-4:2016, the general technical delivery requirements of ISO 404 are applicable.

This document specifies a potentiometric or visual titration method for the determination of manganese content in alloyed steels. The method is applicable to manganese mass fractions between 2 % and 25 %. Vanadium and cerium interfere with the determination. If the mass fraction of cerium in the sample is less than 0,01 %, or the mass fraction of vanadium in the sample is less than 0,005 %, the interference is negligible, otherwise theoretical corrections are necessary.

This document specifies technical delivery requirements for the surface quality of round bars, squares, hexagons and wire rod in the hot rolled condition with nominal dimensions dN from 5 mm to 200 mm. This document is applicable to bright products and tool steels, if agreed at the time of enquiry and order between manufacturer and purchaser. By agreement between manufacturer and purchaser, this document can also be applied to other special profiles. This document is particularly applicable to steels for engineering and structural applications. This document does not include any requirements for the permissible depth of surface decarburization. NOTE The determination of depth of surface decarburization is presented in ISO 3887. The material standards for steel bars and wire rod can exclude the application of one or other of the surface quality classes of this document.

ISO 17781:2017 specifies quality control testing methods and test conditions for the characterization of microstructure in relation to relevant properties in ferritic/austenitic (duplex) stainless steel components supplied in the solution annealed condition and fabrication welds in the as welded condition.
ISO 17781:2017 supplements the relevant product and fabrication standards with respect to destructive testing methods including sampling of test specimens, test conditions and test acceptance criteria to show freedom from deleterious intermetallic phases and precipitates in duplex stainless steels. In addition, this document specifies the documentation of testing and test results by the testing laboratory.
NOTE 1 This document is based upon experience with duplex stainless steels in offshore oil and gas industry applications including topside and subsea hydrocarbon service, sea water service, as well as structural use.
NOTE 2 The austenite spacing is relevant to the susceptibility of duplex stainless steels to hydrogen-induced stress cracking (HISC) in subsea applications where cathodic protection is applied. This falls outside the scope of this document. Reference is made to DNV/GL RP-F112[4].
