1,Description:
Stainless steel equipment is fabricated to exhibit damage, defects, and a number of surface-affecting substances, such as dust, floating or embedded iron powder, heat-tempered colors and other oxidized layers, rust spots, abrasive burrs, weld-arcing stains, welding spatters, fluxes, weld imperfections, oils and greases, residual adhesives and paints, and chalk and marker pen marks.The vast majority of these are underappreciated or poorly done because their harmful effects are overlooked.However, they are potentially harmful to the oxidized protective film.Once the protective film is damaged, thinned or otherwise altered, the stainless steel below will begin to corrode.Corrosion is generally not over the entire surface, but at or around the defect.This localized corrosion is usually pitting corrosion or crevice corrosion, these two kinds of corrosion will be to the depth and breadth of the development, and most of the surface is not eroded!
Bolt: Mechanical part, cylindrical threaded fastener with nut. A fastener consisting of a head and a screw (a cylinder with external threads) in two parts, to be fitted with a nut, for fastening two parts with a through hole. This type of connection is called bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
2,Applications:
Bolts are indispensable in daily life and industrial production and manufacturing, and bolts are also known as industrial meters. It can be seen that the use of bolts is wide. The application range of bolts is: electronic products, mechanical products, digital products, power equipment, mechanical and electrical machinery products. Bolts are also used in ships, vehicles, hydraulic projects, and even chemical experiments. Bolts are used in a lot of places anyway. Such as the precision bolts used in digital products. Miniature bolts for DVDS, cameras, glasses, clocks, electronics, etc. General bolts for televisions, electrical products, Musical Instruments, furniture, etc.; For projects, buildings and Bridges, large bolts and nuts are used; Transportation equipment, aircraft, trams, cars, etc., are used with large and small bolts. Bolts have important tasks in industry, and as long as there is industry on Earth, the function of bolts will always be important.
| 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 |
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:
Ordinary bolt head is very thick, difficult to deform, if vibration occurs after good, but also need to re-tighten; The flange with a thin part, can be slightly deformed, can be locked more firmly. There is also the fact that if it goes to the hole, the ordinary bolt can not use the tool, the head of the flange bolt is smaller, the following flange plate also plays a fastening role, but it can be used on the special tool to the hole, and the hexagonal bolt is about the same principle. Another is the flange top flat pad to use, in the softer, non-wear-resistant material is safer, will not cause perforation
