1   Scope This document specifies the mechanical and physical properties of bolts, screws, studs and nuts, with coarse pitch thread and fine pitch thread, made of corrosion-resistant stainless steels (i.e. martensitic stainless steels and precipitation hardening austenitic stainless steels ) and nickel alloys, intended for use at high temperatures up to 800 °C. Tests in accordance with Clause 9 are performed at the ambient temperature range of 10 °C to 35 °C, and other tests can be performed at higher temperatures, see Clause 10. NOTE Fasteners specified in this document are also suitable when used at low temperatures, typically down to -50 °C. For more information, see ISO 3506‑6. The term “fasteners” is used in this document when bolts, screws, studs and nuts are considered all together. ISO 3506‑6 provides general rules and additional technical information on suitable stainless steels and nickel alloys as well as their properties. This document applies to fasteners: — 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 M3 to M39, and fine pitch thread M8×...
