Alloy-steel And Stainless Steel Bolting For High

Alloy-Steel and Stainless Steel Bolting for High Temperature or High Pressure Service and Other Special Purpose Applications1 This standard is issued under the fixed designation A193/A193M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Grades and Materials for Boiler and Pressure Vessel Steel Stainless steel is mainly used when high corrosion and oxidation resistance is required, alloy steel product developed with over 12% of chromium improved growth of chemical processing and power generating industries, including pressure vessel equipments, boilers, cylinders, etc. Stainless steel has developed into 3 common types:Austenitic, Martensitic, Ferritic, there are also special types:duplex, precipitation hardening and super alloys.

High Temperature Characteristics of Stainless Steel

temperature of 750°F (399°C); the ½% molybdenum alloy steels to approximately 850°F (454°C); and the stainless steels to considerably higher temperatures depending upon the type used. It is important to recognize that for high-temperature service, strength at temperature is related to time at temperature. Allowable Deformation High-temperature creep rupture of low alloy ferritic undergo creep deformation and damage at high temperatures; and, a thermodynamic framework is provided for the deformation rate potentials used in the equations. Finite element continuum damage mechanics studies have been carried out using these constitutive equations on butt-welded low alloy ferritic steel pipes subjected to combined internal pressure and axial loads at 590 and 620 8C. Metals & Alloys for High-Temperature Services 602A Alloy. 602A is an austenitic heat resistant alloy that displays superior strength in the face of temperatures of up to 1200 degrees C, (2200 degrees F). In fact, its the single strongest and most oxidation resistant wrought alloy currently available for service above 1040 degrees C (1900 degrees F).
