This section is GB/T Part of 163,098.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 3098.16-2000 "Mechanical properties of fasteners stainless steel set screws." Section compared with the GB/T 3098.16-2000 The main changes are as follows.

--- "At an ambient temperature of 15 ~ 25 °C", the words "at an ambient temperature of 10 °C ~ 35 °C" (see Chapter 1, 2000 edition Chapter 1);

--- The "hardness level" instead of "Performance Level" (see Chapter 1, Chapter 1 of the 2000 edition);

--- Added "set screws and similar fasteners according to GB/T 5267.4 passivation treatment, can increase marked 'P'" (see Figure 1);

--- Adjust the packaging and labeling requirements, the new "mark or label shall include producers and/or distributors trademark (or identification)" and "press GB/T 90.3 predetermined production lot "(see 3.2.4);

--- Adjust the surface finishing requirements, the new "special orders by set screws and similar fasteners manufactured, should additional signs and both for fasteners, also apply to the label. However, set screws and similar fasteners warehouse sent the additional flag is only applicable for the label "(see 3.3);

--- New "NOTE. Table 2 gives the chemical composition of the GB/T 3098.6-2014 chemical composition of Table 1 is consistent with the relevant group" (See Chapter 4).

The partial modification of the use of ISO 3506-3:2009 "Mechanical properties of corrosion-resistant stainless steel fasteners - Part 3. Set screws and similar Fasteners not under tensile stress "(English version), the main changes are as follows.

--- Name to "Mechanical properties of fasteners stainless steel set screws";

--- Normative reference document, instead of using our standards with international standards (see Chapter 2).

This part is proposed by China Machinery Industry Federation.

This part of the National Standardization Technical Committee fasteners (SAC/TC85) centralized.

Mechanical properties of fasteners stainless steel set screws

1 Scope

GB/T 3098 provisions of this section by the corrosion-resistant austenitic stainless steel, at an ambient temperature of 10 °C ~ 35 °C under the conditions of feed when the line test, the mechanical properties of tight set screws and similar fasteners not under tensile stress. At higher or lower temperatures, their performance may be different.

This section applies to set screws and similar fasteners.

--- Nominal thread diameter 1.6mm<=d<=24mm;

--- Diameter and pitch, etc. in line with the common thread GB/T 192, GB/T 193 and GB/T 9144 provisions;

--- Any shape.

This section does not apply to screws with special performance requirements, such as weldability.

NOTE. As long as the hardness level can meet all the technical requirements of the physical and mechanical, the system marks the provisions of this section may be used beyond the provisions of this chapter Specifications (Such as d > 24mm).

This section does not provide corrosion and oxidation under special circumstances.

Corrosion resistance, oxidation resistance and mechanical properties of high temperature or below zero use, either by the user according to the manufacturer with every special occasion Protocol. Appendix D shows the temperature under the relevant conditions, the carbon content of the risk of intergranular corrosion depends on the carbon content of the case.

This section is a corrosion-resistant stainless steel fasteners according to the hardness grade classification.

All austenitic stainless steel fasteners in a solid solution state, usually non-magnetic; after cold deformation, will show some obvious magnetism (See Appendix E).
