This part of GB/T 3098 specifies the mechanical and physical properties of the nuts with coarse thread and fine pitch thread made of carbon steel or alloy steel when tested at ambient temperature range of 10C to 35C. Nuts conforming to the requirements of this part may not retain the specified mechanical and physical properties at elevated and/or lower temperature.

This Part of GB/T 3098 specifies the materials, technical requirements and test methods of tapping screws. This Part is applicable to the tapping screws manufactured by carburizing carbon steel, thread specification of ST2.2~ST9.5; and thread conforms to the provisions of GB/T 5280.

This Part of GB/T 70 specifies the type and dimension, technical conditions and markings of hexagon socket button head screws with Thread Specification M3~M16, Property Class 08.8, 010.9, 012.9, 012.9, A2-70, A2-80, A3-70, A3-80, A4-70, A4-80, A5-70 and A5-80, Product Grade A, and the carrying capacity is reduced as per Table 3.

This Part of the GB/T 2449 specifies the requirements, sampling, test methods, inspection rules, marks, packaging, transportation, storage and safety of the liquid sulphur for industrial use. This Part is applicable to the liquid sulphur for industrial use produced from recycled petroleum refinery gas and natural gas. For the liquid sulphur for industrial use produced by using other processes, this Part may also be referred to for implementation.

This Part of GB/T 3098 specifies the mechanical properties of nuts made of austenitic, martensitic and ferritic steel grades of corrosion-resistant stainless steels, when tested over an ambient temperature range of 10 ~ 35 degree Celcius. Properties vary at higher or lower temperatures.

This Standard specifies the requirements, test methods, inspection rules, marking, package, transportation, storage, order sheet (or contract), and the like contents of seamless copper alloy tube for condenser and heat-exchanger. This Standard is applicable to the seamless copper alloy tubes used by thermal power generation, ship, offshore oil, machinery, chemical and other industrial sectors to manufacture heat-exchanger and condenser.

This Part of GB/T 3098 specifies the mechanical and physical properties of set screws and similar threaded fasteners with specified hardness classes, which are manufactured by carbon steel or alloy steel, and tested at the environmental temperature of 10C~35C. At such environmental temperature range, assess the fasteners (including set screws and similar threaded fasteners with specified hardness classes, the same below) as per the requirements of this Part. The fasteners meeting the requirements of this Part shall be classified as per the specified hardness class, and are only applicable to the compressive stress.

This Standard specifies the terms, definitions, components, materials, grading, code, technical requirements, test methods, inspection rules, packaging, mark, transportation and storage of white Portland cement. This Standard is applicable to the production and application of white Portland cement.
