Superior Joining Technologies, Inc. has the experience and expertise working with different grades of carbon steel, making sure our carbon steel CNC machined parts and carbon steel GTAW welding services beat your expectations for quality and timely completion. Carbon steel is an iron-carbon alloy with carbon content ranging from .0218 percent to 2.11 percent. It also contains small amounts of silicon, manganese, sulfur, and phosphorus. Carbon steel has a higher carbon content than mild steel making it less ductile, but stronger. Generally, the higher the carbon content in carbon steel, the higher the hardness and strength, but the lower the plasticity.

CNC machining decreases manufacturing costs, improves production speed, and increases efficiency. We provide tolerances as close as +/- .0002” and complete intricate, finished parts quickly and on time. ## Carbon Steel GTAW Welding Services Superior Joining Technologies, Inc. provides high-quality carbon steel [manual welding](https://www.superiorjt.com/services/gas-tungsten-arc-welding/nadcap-manual-gtaw) in the form of our NADCAP accredited Gas Tungsten Arc Welding (GTAW) or Tungsten Inert Gas (TIG) Welding. We provide clean, highly controllable, and precise welds for carbon steel. Additionally, we offer microscopic laser beam welding (Micro LBW), laser welding, seam welding, and resistance spot welding. All of our carbon steel GTAW welding services are suitable for use with carbon steel. ### CNC Machined and/or GTAW Welded Carbon Steel Parts - Automobile body components - Construction and bridge components - Crankshafts - Gears - Machinery parts - Cutting tools - Springs - High strength wire - Dies ### Industry Applications Carbon steel’s strength and ductility depend on its carbon content. This large range in properties makes carbon steel a commonly used metal in a wide variety of industries. These include: - Defense - [Medical](https://www.superiorjt.com/medical) - Dental - Automotive - Electrical - Motion control and instrumentation - Sporting goods - Consumer goods ### Carbon Steel Grades Superior Joining Technologies, Inc. will work with any grade of carbon steel. Some of the more popular grades are listed below. - T7, T8 - Make parts that bear a certain impact and require toughness - Hammer, punch, chisel, woodworking tools, and scissors - T9, T10, T11 - Tools with low impact, high hardness, and wear resistance - Taps, small drills, dies, and hand saw blades - T12, T13 - Tools that are not impacted - Files, scrapers, razors, and measuring tools - 08F Steel - Low carbon content, good plasticity, low strength - Used for stamping parts such as automobile and instrument housing - 20 # Steel - Good plasticity and weldability - Used for parts with low strength and carburized parts - Examples include hoods, welding containers, small shafts, nuts, washers, and carburized gears - 45 # Steel - Good comprehensive mechanical properties after quenching and tempering - Used for mechanical parts with large force such as gears, connecting rods, machine tools, and spindles - 60 # Steel - High strength - Used to manufacture springs, wheel flanges, and low-speed wheels ### **Rely on Superior Joining** Superior Joining certified AS9100, ISO9001, and is a NADCAP-accredited facility. We are a carbon steel CNC machined parts provider with processes that are approved by Boeing, GE, Unison, Collins Aerospace, and Safran.
