31、506-1:2009) has been prepared by Technical Committee ISO/TC 2 “Fasteners” in Introduction 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 a
32、nd low-alloy steel fasteners. Ferritic and austenitic stainless steels are strengthened only by cold working 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 pro
33、perty classes and the test procedures for mechanical properties. The latter differ from the carbon steel and low-alloy steel fastener test procedures with regard to the measurement of the stress at 0,2 % permanent strain (yield stress) and ductility (total elongation after fracture). DIN EN ISO 3506
34、-1:2010-04 EN ISO 3506-1:2009 (E) 4 1 Scope This part of ISO 3506 specifies the mechanical properties of bolts, screws and studs 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. Propertie
35、s vary at higher or lower temperatures. This part of ISO 3506 applies to bolts, screws and studs with nominal thread diameter d u 39 mm, of triangular ISO metric threads with diameters and pitches in accordance with ISO 68-1, ISO 261 and ISO 262, and of any shape. It does not apply to screws with sp
36、ecial properties, such as weldability. 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 39 mm), provided that all applicable mechanical and physical requirements of the property classes are met. This part of ISO 3506 does not
37、define corrosion or oxidation resistance in particular environments. However, some information on materials for particular environments is given in Annex E. Regarding definitions of corrosion and corrosion resistance, see ISO 8044. The aim of this part of ISO 3506 is the classification of corrosion-
38、resistant stainless steel fasteners1)into property classes. Some materials can be used at temperatures down to 200 C, while 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 F. Corrosion and oxidation perform
39、ances 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 G shows how the risk of intergranular corrosion at elevated temperatures depends on the carbon content. All austenitic stainless steel fa
40、steners are normally non-magnetic in the annealed condition; after cold working, some magnetic properties can be evident (see Annex H). 1) The term “fasteners” is used when bolts, screws and studs are considered all together.
