Carbon Steel
Carbon Steel Forged Parts
Carbon Steel is one of the most widely used metals for open die forgings. Its tensile strength, hardness, and hardenability through heat treatments are vital for its many end uses for moving parts in machinery, shapes for heavy equipment, and structural components requiring resistance to wear or impact. Carbon steel is economical for various applications depending upon the environment of its end use. It is often used for intricate shapes because it is easy to machine.
The carbon content of the steel defines in mechanical properties. 1018, 1020, and 1025, all low carbon steels, are most commonly used for forgings. 1040 and 1045 medium carbon steels that can be quenched and tempered are more durable medium carbon steels widely used for their higher strength and toughness. High carbon steel with 0.55% carbon content or greater are selected for their high hardness and resistance to impact or wear.
Common specifications for carbon steel include:
ASTM A668 Classes A-F (Classes G-N are alloy steels), AISI, AMS, API, UNS and other industry standard specifications depending upon the shape of the carbon steel for its end use.
The chemical and mechanical properties of carbon 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.
Carbon steel is not used in corrosive environments or high temperatures conditions, although it can withstand 1200F (650C) in some oil and gas pipeline uses. The strength of carbon steel increases as temperature is reduced although the metal becomes brittle at -20F (-28.9C) risking fracture when subjected to impact loading.
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.
