What Are Stainless Steel Cleats and Fairleads for?
Cleats are paired vertical wooden or iron posts mounted either aboard a ship or on a wharf, pier or quay. Stainless steel cleats: what are them and what are they for? The posts are used to secure mooring lines, ropes, hawsers, or cables. Cleats are carefully manufactured and maintained to avoid any sharp edges which […]
Sailboats – Circuit for Operating the Sails
Sailboats (or sailing boat) is a boat propelled partly or entirely by sails smaller than a sailing ship. In fact, the motor provides support action specifically during ports maneuvers. Indeed, the sailboats have a particular type of equipment on board. The boom: what is this? In sailing, a boom (see fig.1) is a spar (pole), […]
AISI 304 / 316 Stainless Steel Rings: a Thousand Uses
Stainless steel rings have a wide range of applications in the marine industry. Their use mainly depends on the type of stainless steel they are made from. The grades AISI 304 and AISI 316 refer to austenitic stainless steels containing generally more than 16% chromium and more than 6% nickel as the second main alloying element. AISI 316 and AISI 304: what are the differences? AISI 304 stainless steel is commonly used for kitchen equipment, sinks, cutlery, and similar applications. In […]
A4 Stainless Steel Flush Lift Rings: What Are They Used for?
The locker is a pit space with a walkable hatch opening from the upper side of the compartment. Usually, it is hermetically sealed. This locker is located on the boat’s upper deck and it is primarily used for the stowage of small materials, which are often useful for navigation, during the riggings or in case […]
The Turning – What Is It?
After our previous blog post about plastic cold deformation, today we would like to talk about turning. Turning is a machining process in which a cutting tool, typically a non-rotating tool bit, follows a helical tool path while the workpiece rotates. The turning process: how and when is it used? The tool’s axes of movement may follow a straight line or a series of curves or angles, but the movement is essentially linear. Usually, the term turning refers to the […]
Cold Plastic Deformation – What Is It?
Cold plastic deformation – The stainless steels (in particular the austenitic ones) have an obvious attitude to be cold formed. Also, these undergo a phenomenon of strain hardening that is, the raising of mechanical properties as the ultimate tensile strength, yield strength and surface hardness. Molding process: the static pressure or dynamic actions The molding […]
Investment Casting: Discover All Uses.
The investment casting is a nearly finished form castings process. To obtain the tolerance requirements, this form requires little subsequent processing to machine tools. The investment casting in ancient times. Some history The microcast technique (or investment casting) was used by ancient peoples for the production of various bronze tools and objects, including also monumental […]
Stainless Steel Pins – When to Use Them?
In mechanics, the stainless steel pins are mechanical element that needs an extremely accurate coupling. It may has the conical, cylindrical or spiral form. Stainless steel pins: all uses Stainless steel pins are produced according to very strict tolerances; this also applies to the corresponding holes, that they are typically machined processed by reaming. The stainless steel […]
Parallel Keys – How to Use Them?
Stainless steel parallel key is a mechanical transmission connection between a shaft and a hub, with a wheel. (e.g. a gear wheel or a bullwheel) Stainless steel parallel keys: What are them? Parallel key is essentially a stainless steel parallelepiped. According to UNI 6604 standard, it shall be constructed of stainless steel with a breaking […]
Hexagon Socket Screws – What Benefits?
Hexagon Socket Screws, Brugola, Allen, Hex Key, socket wrench? You are thinking: “But that is 4 different types of screws”. They aren’t! It is a single screw for so many name:a type of mechanical key characterized by an hexagonal section; its technical name depends on the country. In 1910, the American William G. Allen has […]
