Carbon alloys are steel‑based materials engineered through the controlled addition of carbon and other alloying elements to enhance strength, hardness, machinability, and wear resistance. These alloys offer predictable mechanical and ferromagnetic properties, making them well suited for demanding applications across oil and gas, power generation, heat exchangers, water treatment, paper and pulp, aerospace, and select chemical processing environments. Carbon alloys are commonly used where structural integrity, durability, and cost‑effective performance are critical under mechanical load and elevated operating conditions.
SA-105/SA-350 Grade LF2 Steel
SA-105/SA-350 Grade LF2 Steel is primarily used in forged steel components for piping systems requiring performance across low-temperature, ambient, and elevated-temperature service conditions.
Alloy 1045 TGP
AISI 1045 is a medium carbon steel containing approximately 0.45% carbon that can be hardened by heat treatment to a maximum surface hardness of approximately Rockwell C 54-60 after flame or induction hardening.
Alloy 4140
4140 alloy steel is a medium carbon, chromium-molybdenum, through-hardening alloy steel that has a good hardenability with high strength and toughness as well as good fatigue and impact resistance after heat treating.
Alloy 4340 HT
4340 alloy steel is a medium carbon nickel-chromium molybdenum alloy steel that creates an excellent combination of ductility, toughness, and strength after heat treating.
Alloy 8620 Aircraft Quality
Alloy 8620 Aircraft Quality (AQ) is a premium carburizing alloy steel engineered for demanding applications that require exceptional toughness, strength, and wear resistance.
Alloy 9310 Aircraft Quality
9310 alloy steel is a low carbon nickel-chromium-molybdenum case-hardening steel, with good strength and toughness properties. It shows high hardenability, high core hardness and high fatigue strength.
