M2 M2.5 Stainless Steel SUS 304 SUS 316 Slotted Drive Truss Head Machine Screw
1,Description:
SUS304 refers to 304 stainless steel. SUS is a Japanese material standard. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. SUS304 indicates that it is produced in accordance with the Japanese standard.
304 is equivalent to China's (0Cr18Ni9) stainless steel. Due to its high nickel content and austenitic single-phase structure at room temperature, it has higher corrosion resistance compared to Cr13 stainless steel. It also features high plasticity and toughness at low, room and high temperatures, as well as good cold working and weldability. However, its strength at room temperature is relatively low, with a greater tendency for intergranular corrosion and stress corrosion, and its machinability is poor
| Applications |
| car | In high-strength applications such as automotive engines, heavy-duty machinery, and bridge construction, they are preferred for their larger support area and better anti-loosening performance. |
| mechanical | Mechanical, electronic, automotive, construction and other fields, used to connect various mechanical parts, circuit boards, engines, transmissions, building structures, etc |
| energy | For the energy industry, brackets and fixtures used to connect power generation equipment and transmission lines
|
| architectural | In the field of construction engineering, shipbuilding, and petrochemical industry, it is used to connect building structures, improve the navigation safety and stability of ships, and ensure the safety and stability of petrochemical equipment |
Both 304 and 303 are made of stainless steel, but their compositions are different. SUS303 and SUS304 are the names used in Japan, while in China they are respectively called Y1Cr18Ni9 and 0Cr18Ni9. In China, the international chemical element symbols and the national symbols are used to represent the chemical components, and the content of the components is indicated by Arabic letters. The difference in chemical composition between the two can be seen from their structural formulas. These two have excellent anti-corrosion capabilities, but 304 is better. The comparison of relevant materials and the experimental data show that stainless steel also rusts after 168 hours of salt spray test. In other cases, to achieve good anti-corrosion effects, anti-rust oil can be applied, but the effect is limited and inconvenient for production and installation. It mainly depends on what kind of effect you want to achieve and what kind of material to choose. Currently, the relatively standard sequence is: Common blue-white zinc-coated carbon steel < black-zinc-coated carbon steel < zinc-nickel-coated carbon steel < stainless steel.
3,Specifications:
| material |
| aluminium | Aluminum has excellent thermal and electrical conductivity. However, aluminum is naturally soft and may produce gelatinous buildup after processing. If not properly operated, it is difficult to cut during processing. |
| titanium | Edm machining is well suited for titanium because the process can withstand the viscosity of this alloy and break down lengthy chips. However, deionized water is needed as a medium to help control the heat generated during processing.
|
| steel | Steel is a very strong metal, and many manufacturers tend to use wire cutting machines instead of CNC machines for machining complex steel features. However, this material generates a lot of heat, so necessary precautions need to be taken. |
| brass | Brass has a high tensile strength and is easy to cut by machine. But the cutting speed should be slow because it is a soft metal. |
4,Feature Advantage:
It has excellent corrosion resistance, heat resistance, low-temperature strength and mechanical properties. It is good for hot working such as stamping and bending, with no hardening phenomenon after heat treatment and no magnetism.
304 stainless steel is widely used in the manufacture of corrosion-resistant and formable equipment and components due to its excellent heat resistance. 304 stainless steel has been widely used in industrial equipment such as food, chemical, and atomic energy, as well as in decoration fields, household items, cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical devices, building materials, chemical, food industry, agriculture, and ship components.
