Annealing Annealing is a controlled heat treatment process used to soften metals, improve ductility, reduce internal stresses, and enhance machinability. Read more Brazing Brazing is a precision metal-joining process that bonds two or more metal components using a filler metal heated above its melting point, all while keeping the base materials intact. Read more Gas Carburizing Gas carburizing is a thermochemical heat treatment process used to increase surface hardness and wear resistance while maintaining a tough, ductile core. Read more Gas Nitriding Gas nitriding is a low‑temperature thermochemical heat treatment process that enhances surface hardness, wear resistance, and fatigue strength without the core properties of the material being affected. Read more Neutral Hardening Neutral hardening is used to increase the hardness, strength, and wear resistance of steel components, while preventing unwanted surface chemistry changes. Read more Oil & Specialized Quenching Offering batch, press, plug, and roll quenching services, SST is an industry leader in distortion control for components where dimensional stability is critical. Read more Precipitation Hardening Precipitation hardening, also known as age hardening, is used to significantly increase strength and hardness while maintaining corrosion resistance and dimensional stability. Read more Supply Chain Management At Specialty Steel Treating, we offer more than just heat treating services; we can assist in streamlining our customer’s entire manufacturing process. Read more Vacuum Carburize Vacuum carburizing produces a hard, wear‑resistant surface while maintaining a strong, ductile core. Read more Vacuum Hardening Vacuum hardening is used to increase hardness, strength, and wear resistance while maintaining exceptional surface quality and dimensional accuracy. Read more
