3、This translation has been made basecL on the original Japanese Industrial Standard established by the Minister of Economy, Trade and Industry through deliberations at the Japanese Industrial Standards Committee according to the proposa1 of establishing a Japanese Industrial Standard from The Japan R
4、esearch Institute for Screw Threads and Fasteners (JFRI)/the Japanese Standards Association (JSA), with a draft of Industrial Standard based on the provision of Article 12 Clause 1 of the Industrial Standardization Law. Consequently, JIS B 1054 : 1995 was withdrawn and replaced with Part 1, Part 2 a
5、nd Part 3 of JIS B 1054 : 2001. This Standard employs on the basis of IS0 3506-2 : 1997 Mechanical properties of corrosion-resistant stainless-steel fasteners-Part 2 : Nuts for the purpose of conforming to the International Standard. JIS B 1054 series consist of three parts with the title of Mechani

10、 2001 (IS0 3506-2 : 1997) Mechanical properties of corrosion-resistant stainless-steel fasteners- Part 2 : Nuts Introduction This Japanese Industrial Standard has been prepared based on the first edition of IS0 3506-2 Mechanical properties of corrosion-resistant stainless-steel fasteners-Part 2 : Nu
11、ts published in 1997 without modifying the technical contents. Portions underlined with dots are the matters not stated in the original Interna- tional Standard. 1 Scope This part of JIS B 1054 specifies the mechanical properties of nuts made of austenitic, martensitic and ferritic grades of corrosi
12、on-resistant stainless steels when tested over an ambient temperature range of 15 “C to 25 OC. Properties will vary at higher or lower temperatures. It applies to nuts with nominal thread diameters (d) up to and including 39 mm; of triangular IS0 metric threads with diameters (d) and pitches in acco
13、rdance with JIS B 0205 and JIS B 0207; of any shape; with width across flats as specified in JIS B 1002; with nominal heights greater than or equal to 0.5 d. It does not apply to nuts requiring properties such as - locking abilities; - weldability. This part of JIS B 1054 does not define corrosion o
14、r oxidation resistance in par- ticular environments. 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 tem- peratures down to -200 OC, some can be used at temperatures up to +800 O C in air. In
15、formation on the influence of temperature on mechanical properties is found in annex D. Corrosion and oxidation performances and mechanical properties for use at el- evated or sub-zero temperatures must be the subject of agreement between user and manufacturer in each particular case. Annex E shows
16、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 F). Remarks : The International Standar
17、d corresponding to this Standard is as fol- lows.
