Status: active
Page Count: 36
ICS Code (Nuts): 21.060.20
scope:

This Standard specifies the mechanical properties of nuts made of austenitic, martensitic and ferritic steel grades of corrosion-resistant stainless steels, when tested over an ambient temperature range of 10°C to 35 °C. Properties vary at higher or lower temperatures.

This Standard applies to nuts:

- with nominal thread diameter D ≤ 39 mm;

- of ISO general purpose metric threads based on JIS B 0205-1 with diameters and pitches in accordance with JIS B 0205-2 and JIS B 0205-3;

- of any shape;

- with width across flats as specified in JIS B 1002 (except for those shaded);

- with nominal heights m ≥ 0.5D.

It does not apply to nuts requiring properties such as

- locking abilities, and

- weldability.

NOTE: The designation system of this Standard can be used for sizes outside the limits given in this clause (e.g. D> 39 mm), provided that all applicable mechanical and physical requirements of the property classes are met. This Standard does not define corrosion or oxidation resistance in particular environments. However, some information on materials for particular environments is given in Annex D. Regarding definitions of corrosion and corrosion resistance, see ISO 8044.

The aim of this Standard is the classification of corrosion-resistant stainless steel nuts into property classes. Some materials can be used at temperatures down to -200°C, some can be used at temperatures up to +800 °C in air. Information on the influence of temperature on mechanical properties is found in Annex E.

Corrosion and oxidation performances and mechanical properties for use at elevated or sub-zero temperatures can be agreed on between the user and the manufacturer in each particular case. Annex F shows how the risk of intergranular corrosion at elevated temperatures depends on the carbon content.

All austenitic stainless steel fasteners are normally non-magnetic in the annealed condition; after cold working, some magnetic properties can be evident (see Annex G).

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:

ISO 3506-2: 2009 Mechanical properties of corrosion-resistant stainless steel fasteners-Part 2: Nuts (IDT)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEC Guide 21-1.
