Mechanical properties of corrosion-resistant stainless steel fasteners - Part 1: Bolts, screws and studs
 N JIS B 1054-1

Annotation

This Standard 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. Properties vary at higher or lower temperatures.

This Standard applies to bolts, screws and studs

- with nominal thread diameter ds39 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, and

- of any shape.

It does not apply to bolts, screws and studs with special properties, such as 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 E. Regarding definitions of corrosion and corrosion resistance, see ISO 8044.

The aim of this Standard is the classification of corrosion-resistant stainless steel fasteners 1) 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.
