Book Effect of Forging Strain Rate and Deformation Temperature on the Mechanical Properties of Warm worked 304L Stainless Steel

Download or read book Effect of Forging Strain Rate and Deformation Temperature on the Mechanical Properties of Warm worked 304L Stainless Steel written by and published by . This book was released on 2010 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stainless steel 304L forgings were produced with four different types of production forging equipment - hydraulic press, mechanical press, screw press, and high-energy rate forging (HERF). Each machine imparted a different nominal strain rate during the deformation. The final forgings were done at the warm working (low hot working) temperatures of 816 °C, 843°C, and 871°C. The objectives of the study were to characterize and understand the effect of industrial strain rates (i.e. processing equipment), and deformation temperature on the mechanical properties for the final component. Some of the components were produced with an anneal prior to the final forging while others were deformed without the anneal. The results indicate that lower strain rates produced lower strength and higher ductility components, but the lower strain rate processes were more sensitive to deformation temperature variation and resulted in more within-part property variation. The highest strain rate process, HERF, resulted in slightly lower yield strength due to internal heating. Lower processing temperatures increased strength, decreased ductility but decreased within-part property variation. The anneal prior to the final forging produced a decrease in strength, a small increase in ductility, and a small decrease of within-part property variation.

Book Temperature Effects on the Mechanical Properties of Annealed and HERF 304L Stainless Steel

Download or read book Temperature Effects on the Mechanical Properties of Annealed and HERF 304L Stainless Steel written by Bonnie R. Antoun and published by . This book was released on 2004 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of temperature on the tensile properties of annealed 304L stainless steel and HERF 304L stainless steel forgings was determined by completing experiments over the moderate range of -40 F to 160 F. Temperature effects were more significant in the annealed material than the HERF material. The tensile yield strength of the annealed material at -40 F averaged twenty two percent above the room temperature value and at 160 F averaged thirteen percent below. The tensile yield strength for the three different geometry HERF forgings at -40 F and 160 F changed less than ten percent from room temperature. The ultimate tensile strength was more temperature dependent than the yield strength. The annealed material averaged thirty six percent above and fourteen percent below the room temperature ultimate strength at -40 F and 160 F, respectively. The HERF forgings exhibited similar, slightly lower changes in ultimate strength with temperature. For completeness and illustrative purposes, the stress-strain curves are included for each of the tensile experiments conducted. The results of this study prompted a continuation study to determine tensile property changes of welded 304L stainless steel material with temperature, documented separately.

Book Mechanical Properties of Several Products from a Single Heat of Type 304 Stainless Steel

Download or read book Mechanical Properties of Several Products from a Single Heat of Type 304 Stainless Steel written by and published by . This book was released on 1973 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: From winter meeting of American Society of Mechanical Engineers; Detroit, Michigan, USA (11 Nov 1973). Tensile and stress-rupture tests were run on several products from a 90-ton heat of type 304 stainless steel. The yield stress of the products in the as-received condition varied from 26,500 to 57,200 psi at 75 deg F. There were significant differences between the strengths of various products and considerable variation for a single product due to nonuniform residual cold work. Reannealing 0.5 h at 2000 deg F resulted in yield stresses in the 25,000 to 27,000 psi range; only the properties of the hot- reduced tubing fell below this range. At a test temperature of 1100 deg F, the as-received products had yield stresses from 14,800 to 35,500 psi. Reannealing caused the yield stresses of all but three products to fall in the range 10,200 to 11,700 psi. Stress-rupture tests at 1100 deg F on the reannealed products did not reveal significant variation in properties. (auth).

Book Effect of Pre strain on Mechanical Properties of Low Carbon Steel

Download or read book Effect of Pre strain on Mechanical Properties of Low Carbon Steel written by Muhamad Saiful Zakwan Ramlan and published by . This book was released on 2012 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is about to study the effect of pre-strain on mechanical properties of low carbon steel. The objectives for this project are to differentiate the influence of various pre-strain on mechanical properties of low carbon steel. This project involves analysis of the mechanical properties of low carbon steel. From the material composition test done, the material that are used is low carbon steel AISI1018. Investigate the influence of pre-strain on the mechanical properties and fitness-for-service of the low carbon steel pipeline subjected to large plastic deformation. Axial tensile pre-strains of 1.5, 5 and 10% were applied to bar-type tensile specimens extracted from the longitudinal direction of the pipe body prior to mechanical testing. Tensile test results revealed that yield strength and tensile strength increased with increasing tensile pre-strain. The rate of increase of the yield strength was greater than that of the tensile strength. The engineering and true stress-strain curves of the virgin and pre-strained materials at room temperature. There was no difference between the virgin material and the pre-strain material in the elastic region; however, strain hardening decreased with increased prestrain in the plastic zone. Increasing pre-strain increased yield strength but decreased the strain to fracture. The difference in fracture strain between the virgin and pre-strained materials corresponded to the amount of pre-strain applied prior to the tensile tests.
