DIN EN ISO 3506-3:2010-04 EN ISO 3506-3:2009 (E) 3 This document (EN ISO 3506-3:2009) has been prepared by Technical Committee ISO/TC 2 “Fasteners” in Introduction

30、In the preparation of this part of ISO 3506, special attention has been given to the fundamentally different property characteristics of the stainless steel fastener grades compared with those of carbon steel and low-alloy steel fasteners. Austenitic stainless steels are strengthened only by cold wo

31、rking and consequently the components do not have as homogeneous local material properties as hardened and tempered parts. These special features have been recognized in the elaboration of the hardness classes and the test procedures for mechanical properties. DIN EN ISO 3506-3:2010-04 EN ISO 3506-3

32、:2009 (E) 4 1 Scope This part of ISO 3506 specifies the mechanical properties of set screws and similar fasteners not under tensile stress made of austenitic stainless steel, when tested over an ambient temperature range of 10 C to 35 C. Properties vary at higher or lower temperatures. This part of

33、ISO 3506 applies to set screws and similar fasteners: with nominal thread diameter 1,6 mm u d u 24 mm; of triangular ISO metric threads with diameters and pitches in accordance with ISO 68-1, ISO 261 and ISO 262; of any shape. It does not apply to screws with special properties, such as weldability.

34、 NOTE The designation system of this part of ISO 3506 can be used for sizes outside the limits given in this clause (e.g. d 24 mm), provided that all applicable mechanical and physical requirements of the hardness classes are met. This part of ISO 3506 does not define corrosion or oxidation resistan

35、ce in particular environments. The aim of this part of ISO 3506 is the classification of corrosion-resistant stainless steel fasteners into hardness classes. Corrosion and oxidation performances and mechanical properties for use at elevated or sub-zero temperatures can be agreed on between the user

36、and the manufacturer in each particular case. Annex D 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 b

The designation of the material consis

43、ts of two blocks, which are separated by a hyphen. The first block designates the steel grade and the second block, the hardness class. The designation of the steel grade (first block) consists of the letter A for austenitic steel, which indicates the group of steel and a digit, which indicates a ra

44、nge of chemical compositions within this steel group (see Table 2). The designation of the hardness class (second block) consists of two digits representing 1/10 of the minimum Vickers hardness and the letter H, referring to hardness (see Table 1).
