Free-machining grade with reduced molybdenum and correspondingly increased phosphorus and sulfur for automatic machine screw parts as well as surgical implants and pharmaceutical processing equipment. 316N: 16–18: 10–14: 0.08: 2: 0.75: 0.045: 0.03: 0.10–0.16: 2.0–3.0: High-nitrogen grade with increased resistance to pitting and to ...
The material used for ordinary shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding. [citation needed]
AerMet alloy is an ultra-high strength type of martensitic [1] alloy steel. The main alloying elements are cobalt and nickel, but chromium, molybdenum and carbon are also added. Its exceptional properties are hardness, tensile strength, fracture toughness and ductility. [2] Aermet is weldable with no preheating needed. [3]
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution.
Maraging steel is used in oil and gas sector as downhole tools and components due to its high mechanical strength. [22] The steel's resistance to hydrogen embrittlement is critical in downhole environments where exposure to hydrogen sulfide (H₂S) can lead to material degradation and failure.

A V-drive is a power transmission system for boats that consists (usually) of two gearboxes, two drive shafts, and a propeller.. Whereas the conventional arrangement sites the engine with its gearbox aft, driving the propeller shaft directly, in a "V-drive" layout, the engine is reversed, to have the gearbox in front.
The scents of cinnamon and star anise add big flavors to this quick soup. Butter adds body and a silky texture. Fresh udon noodles take only a few minutes to cook, but dry udon noodles work well ...
