This part of JIS B 1054 specifies the mechanical properties of bolts, screws and studs made of austenitic, martensitic and ferritic grades of corrosion-resistant stainless steels when tested over an ambient temperature range of 15 degree C to 25 degree C. Properties will vary at higher or lower temperatures. It applies to bolts, screws and studs - with nominal thread diameter (d) up to and including 39 mm; - of triangular ISO metric threads with diameters and pitches in accordance with JIS B 0205 and JIS B 0207; - of any shape. It does not apply to screws with special properties such as weldability. This part of JIS B 1054 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 part of JIS B 1054 is a classification into property classes of corrosion-resistant stainless steel fasteners. Some materials can be used at temperatures down to - 200 degree C, some can be used at temperatures up to + 800 degree C in air. Information on the influence of temperature on mechanical properties is found in annex F. Corrosion and oxidation performances and mechanical properties for use at elevated or sub-zero temperatures must be the subject of agreement between user and 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 fasteners are normally non-magnetic in the annealed condition; after cold working, some magnetic properties may be evident (see annex H).
