Stainless Steel Hex Bolt SS316 M4 5/16 Inch Polished Corrosion Resistance Marine Applications High Durability
Product Description:
The SS316 hex bolt is designed to offer excellent corrosion resistance, particularly in marine and coastal environments. SS316 stainless steel contains molybdenum, which provides enhanced resistance to corrosion from seawater, making it ideal for marine equipment, shipbuilding, and offshore applications. The M4 size with a 5/16-inch thread ensures secure fastening in smaller components or machinery, offering high strength despite its compact size. The polished finish not only improves the bolt’s aesthetic appeal but also provides additional protection against saltwater and other corrosive elements. This hex bolt is perfect for marine applications, including boat construction, coastal infrastructure, and offshore platforms, where rust and corrosion resistance are paramount.
Applications
Polishing is a processing method that uses mechanical, chemical or electrochemical action to reduce the surface roughness of a workpiece to obtain a bright, flat surface. It is the use of polishing tools and abrasive particles or other polishing media on the surface of the workpiece to carry out the finishing process.
Polishing can not improve the dimensional accuracy or geometric precision of the workpiece, but to get a smooth surface or mirror luster for the purpose, sometimes also used to eliminate the gloss (matte). Polishing wheels are usually used as polishing tools. Polishing wheel is generally made of multi-layer canvas, felt or leather stacked, both sides of the metal plate clamping, the edge of the wheel coated with a uniform mixture of micro-powder abrasives and grease and other polishing agents.
Polishing, high-speed rotation of the polishing wheel (circumferential speed of more than 20 m / s) pressed to the workpiece, so that the abrasive on the surface of the workpiece to produce rolling and micro-cutting, so as to obtain a bright processing surface, the surface roughness is generally up to Ra0.63 ~ 0.01 microns; when the use of non-greasy matte polishing agent, can be matte to improve the appearance of the surface of the bright. Mass production of bearing steel ball, often using roller polishing method.
