标准范围
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.
