  • Carbon Paraequilibrium in Austenitic Stainless Steel
    Carburization of austenitic stainless steels under paraequilibriumconditions-i.e., at (low) temperatures where there is essentially no substitutional diffusion-leads to a family of steels with remarkable properties: enhanced hardness, resulting in improved wear behavior, enhanced fatigue
  • Colossal Carbon Supersaturation in Austenitic Stainless Steels Carburized at Low Temperature (.pdf)
    A novel, low-temperature (470°C) gas-phase carburization treatment, developed by the Swagelok Company, increases the surface hardness of 316 austenitic stainless steels from 200 to 1000 HV25 and improves the corrosion resistance
  • Tensile Residual Stress Fields Produced In Austenitic Alloy Weldments (.pdf)
    Residual stresses developed by prior machining and. welding may either accelerate or retard stress corrosion. cracking (SCC), in austenitic alloys, depending upon. their magnitude and sign. A combined x-ray diffraction. (XRD) and mechanical technique was used to. determine the axial and hoop
  • Custon 450 & Custom Alloy
    When austenitics aren't strong enough and martensitics do not provide enough corrosion resistance, there is custom 450 steel. This powerful stainless steel splits the difference between the two, providing uncommon strength and corrosion resistance in a single package. No wonder it finds uses across
  • Surface Chemistry Improvements on 316L Stainless Steel Weld
    Passivation of austenitic stainless steel surfaces has been practiced on high purity water systems for many years, and is. generally defined as the removal of iron and iron compounds from the surface to improve the passive film and increase. corrosion resistance. The surface chemistry, structure
  • Stainless Steel
    Stainless steels are highly corrosion resistant, ferrous alloys that contain chromium and/or nickel additions. There are three basic types of products: austenitic stainless steels, ferritic and martensitic stainless steels, and specialty stainless steels and iron superalloys. Austenitic stainless
  • Iron-Based Superalloys
    that are austenitic and are strengthened by a sequence of hot and cold working (usually, forging at 2,000 to 2,100 F followed by finishing at 1,200 to 1,600 F), and austenitic alloys strengthened by precipitation hardening. Some metallurgists consider the last group only as superalloys, the others
  • Precipitation Hardening
    : martensitic, semi-austentic and austenitic.
  • Stainless Steel
    One of the features that characterize stainless steels is a minimum 10.5% chromium content as the principal alloying element. Four major categories of wrought stainless steel, based on metallurgical structure, are austenitic, ferritic, martensitic, and precipitation hardening. Cast stainless-steel
