Stainless Steel
Stainless Steel Forged Parts
Stainless Steel is one of the most versatile metals for a wide variety of forged parts and materials for across all light and heavy industries for its corrosion resistance, durability, strength, and visual appeal. Stainless steel forgings are used in nearly all transportation industries, including food service, healthcare, construction, defense, machinery building, energy, engine and turbine, gear, pulp and paper, oil and gas, petroleum and chemicals, marine, offshore, and shipbuilding.
The austenitic 300-Series stainless steels are iron-based chromium-nickel materials designed to resist corrosion, resist wear, and hold strength at elevated temperatures, which makes this series of metal an excellent choice for thousands of end uses. The martensitic 400-Series is commonly used in agricultural equipment, gas turbine exhaust systems, and places where more formability is required. The martensitic precipitation hardened (PH) grades, such as 13-8, 15-5, and 17-4, were chemically crafted for hardness, corrosion resistance, and transverse properties, making them suitable for valves, aircraft parts, gears, and pump parts.
The duplex stainless steels, such a 2205 (UNS S32205), are two-phase alloys (thus, Duplex) containing equal portions of ferritic and austenitic phases in their microstructure. These provide the corrosion resistance of the austenitic stainless steels but with greater strength. Common uses include tanks, piping, process vessels, and structural applications. There is also a subgroup of duplex stainless steels known as Super Duplex that exhibit even higher corrosion resistance and mechanical strength due to a higher alloy content of chromium, molybdenum, and nitrogen.
Common stainless steels include:
304/304L, 316/316L, 321, 410, 416, 420, 422, and 431, 2205 and 2207. Common specifications include ASTM A182 F-Series, A276, A564, A705, A688, AISI, AMS, ASME, UNS, and international standards depending upon the shape of the alloy steel for its end use.
The chemical and mechanical properties of stainless steel make it an excellent choice for component parts finish machined from round, flat, square and hex bars, blocks and rectangles, discs and rings, cylinders, or shapes with steps, flanges, or complex finish machining requirements.
Stainless steels are used for their strength, heat, and corrosion resistance for turbine shafts, gears, heat exchangers, exhaust systems, pipelines, storage tanks, bridges, tunnels, automotive parts, train components, aircraft, medical equipment, and food processing surfaces. It also performs well in saltwater environments for structural components in sea turbines, shafts, gears, blades, and fittings.
All Metals & Forge Group takes great pride in maintaining one of the most stringent ISO9001, AS9100 quality systems in the open die forging and seamless rolled ring industry. It begins with learning the customer’s end use, required forging surface condition, mechanical properties of the specified material and alloy, forged shape, heat treatment, delivery need, and competitive price, coupled with forging soundness proven by ultrasonic testing, and care in packing goods to arrive in pristine condition at the customer’s desired location. Every step is monitored by the quality system at AMFG and continuously improved.
AMFG performs rough machining to within 3mm of finish dimensions to reduce the CNC cost at the customer’s machine shop for all the forged shapes the company produces. The rough machine surface condition is 250 RMS so that proper quality testing can be performed on each part – the AMFG standard.
The company can perform finish machining to within .001 of an inch for final tolerance and 64 or 32 RMS surface finish. This level of quality and precision is unique in an industry where other company’s parts are often delivered black, as forged, or with a rough machined surface of 500 RMS without the internal or external steps and dimensions to reduce machining costs.
From inquiry to invoice, All Metals & Forge Group quality is managed and not assumed. Whether the need is for one part, an entire project, or a production run, AMFG delivers.
