Effect Of Temperature

In this paper, the tensile and strain-controlled cyclic deformation behavior of a ferritic stainless steel which is developed for the exhaust manifold of automobiles is evaluated experimentally at different temperatures. The effect of temperature on monotonic tensile responses such as yield strength and ultimate tensile strength and the effect of temperature and strain amplitude on the evolution of peak stress are assessed. The objective of this study is also to reveal the mixed mode of cyclic hardening–softening behavior of the ferritic stainless steel under strain-controlled fatigue test conditions. A parameter, critical accumulated plastic strain, is introduced to the constitutive equations for the material for describing the hardening - softening responses. The nonlinear constitutive equations for describing the cyclic responses are implemented into Finite Element code using determined parameters for obtaining numerical simulation. The stabilized hysteretic responses obtained from experiment and predicted from numerical simulation are compared and found to be realistic.

Design of a steel tank for the storage of excess energy from thermal solar power plants using molten salts (MS) at 580°C is presented. Energy can be stored up to a week in large containers to generate eight hours of electricity for use at night or to reduce weather related fluctuation at solar thermal energy plants. Our research supported by Office of Naval Research (ONR) presents a detailed design of a cylindrical shell for the storage of high temperature molten salts. The storage shell consists of an inner stainless steel layer designed to resist corrosion and an external steel structural layer to contain the large pressures resulting from the molten salt. The cylindrical tank is 54 feet (16.459 meters) high and has an 80 feet (48.768 meters) diameter, with the salt level at a height of 42 feet (12.802 meters). Given the heat of the molten salt and the size of the tank, the design includes a flat shell cover supported on stainless steel columns and a semispherical utility access dome at the center. Considerations are made for the reduction of strength of steel at elevated temperatures. Layers of external insulation materials are used to reduce heat loss in the storage shell. The design presents a posttensioned concrete foundation analysis for the storage tank, which sits on a layer of sand to allow for thermal expansion.

Abstract EASTERN STAINLESS TYPE 309S is a heat-resisting grade of stainless steel. Because of its high alloy content, it resists scaling up to 2000 F. It also has good tensile and creep properties and elevated temperatures. Type 309S has good ductility and malleability; therefore, difficult shapes and structures can be fabricated easily and it can be machined readily. It can be welded easily and gives strong, ductile welds. Some of its many applications are annealing boxes, boiler baffles, dryers, furnace parts, heat exchangers and oil-refining equipment. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-441. Producer or source: Eastern Stainless Steel Company.
