Specialty forgers can manufacture custom, high-quality, seamless rolled rings in a variety of materials and finishes in as little as eight weeks.
In the shipbuilding industry, high-quality forgings such as long shafts, step shafts, propeller components, and other shaped parts are essential for the construction of cruise liners, super tankers, LNG carriers, drill ships, and other vessels.
These precision-forged parts are often found in applications where it is critical to withstand challenging conditions. Open die forgings and seamless rolled rings have a greater lifespan than other products due to their strength and durability, and are less prone to cracking or warping, making the option ideal for critical components requiring high tensile strength. Depending on the metal and alloy, the rings are also resistant to thermal and chemical damage, which further extends longevity while reducing the need for maintenance, repair, and replacement.
Seamless rolled rings can be used in the manufacture of propeller shafts to ensure steadfast strength and reliability amidst the rigors of the marine environment; steering systems in ships to furnish precision and durability essential for effective navigation and maneuverability; and anchor systems to secure steadfast anchorage across diverse marine conditions in order to safeguard vessels against shifting tides and currents.
With robust, durable, high-performance construction, seamless rolled rings are vital to
marine engineering and shipbuilding endeavors, fortifying vessels to traverse the world’s oceans with unparalleled resilience and reliability.
For shipbuilders, obtaining large heads and seamless rolled rings in a timely manner remains a significant challenge, however. Currently, it may take many months to receive the forged components after placing an order. This delay can have a severe impact on the production and maintenance schedules of firms that depend on replacement parts.
Rings are typically provided with a rough surface finish, which necessitates the use of CNC machining to achieve the required level of smoothness. This poses a challenge for machine shops with a high workload, as allocating machine time for finishing inevitably leads to a decrease in production speed and an increase in costs, ultimately impacting the end-use cost or profitability.
Fortunately, manufacturers can rely on industry-leading forging specialists capable of producing large, custom, seamless rolled rings, and contoured seamless rolled rings with the required surface finish in under two months. One example, All Metals & Forge Group, an ISO 9001:2015 and AS9100D manufacturer of custom and standard open die forged parts and seamless rolled rings can cost-effectively deliver these components with the required finish within 8-10 weeks.
The range of forged products includes rings, discs, hubs, blocks, shafts (including step shafts or with flanges), sleeves, gear blanks, cylinders, flats, hexes, rounds, plates, and custom shapes. Carbon steel, alloy steel, stainless steel, nickel, titanium, and aluminum are among the materials used for forging. These forgings meet rigorous industry specifications such as ASTM, AMS, AISI, ASME, Boeing, SAE, GE, DIN, ASME B 16.5, ASME B16.47, and API 6A.
To optimize efficiency and reduce costs, All Metals & Forge Group frequently provides near-net-shaped forged parts with more refined surface finishes of 250 RMS, and even as low as 125 RMS.
