Scope

This part of GB/T 3098 specifies the mechanical properties of nuts made of austenitic, martensitic and ferritic corrosion-resistant stainless steels when tested at an ambient temperature of 10°C to 35°C. It may perform differently at higher or lower temperatures. Nuts applicable to this section: - nominal thread diameter D ≤ 39 mm; - diameter and pitch comply with GB/T 192, GB/T 193 and GB/T 9144 common threads; - any shape; - - The width across sides complies with the provisions of GB/T 3104; - The nominal height m≥0.5D. This section does not apply to nuts with the following performance requirements: - locking performance; - weldability. This section does not specify corrosion resistance and oxidation resistance in special environments. However, some information about materials in special environments is given in Appendix D. For the definition of corrosion and corrosion resistance, see GB/T 10123. This part classifies corrosion-resistant stainless steel nuts according to their performance grades. Some materials can be used in air to a temperature of -200 ℃, while some materials can be used in air to a temperature of + 800 ℃. For information on the effect of temperature on mechanical properties, see Appendix E. Corrosion resistance, oxidation resistance and mechanical properties for use at high temperatures or below zero can be agreed between the user and the manufacturer for each particular occasion. Appendix F shows the influence of carbon content on intergranular corrosion under high temperature conditions. All austenitic stainless steel fasteners are usually non-magnetic in the solid solution state; after cold deformation, some will exhibit obvious magnetic properties (see Appendix G).
