6、TIES OF METALS PREPARED BY JOHN A.VANECHO AND WARD F.SIMMONS This compilation is a graphical summary of the elevated-temperature mechanical-property data for commercially produced chromium-molybdenum steels.The data were collected through the efforts of the Data and Publications Panel of the ASTM-AS
7、ME Joint Committee on Effect of Temperature on the Properties of Metals.This supplement contains 38 data graphs and about 126 data sheets representing data from 27 Cr-Mo steels.This compilation is a supplement to ASTM DS 6,it does not replace it.This report is intended as a supplement to ASTM DS 6(f
8、ormerly STP 151),which was published in 1953.The original report on chromium-molybdenum steels is a comprehensive report containing data sheets on 52 steels and data summary graphs for 23 steels.Data contained in DS 6 include short-time tensile properties,creep and stress-rupture data,and Larson-Mil
9、ler parameter curves.The Data and Publications Panel has supported a continuous effort to collect high-temperature properties data for metals.These data were,until recently,available in the form of keysort punched cards.The punched-card program was discontinued in June,1965,but all chromium-molybden
10、um steel data collected for this pro-gram are included in this publication.A special collection of additional chromium-molybdenum steel data was also made by the Panel for this supplement.Data were obtained from the following sources:Babcock and Wilcox Co.Crucible Steel Company of America Edward Val

12、een grouped by approximate chemical composition as was done in DS 6.The data graphs include short-time tensile and yield strengths;elongation and reduction of area;creep data for creep rates of 0.001,0.0001,and 0.00001 per cent per hour;and rupture data for times of 100,1000,10,000,and 100,000 hours
13、.Most of the 10,000-hour rupture data and all of the 100,000-hour data were extrapolated.To show the approximate processing each material has received,the figures were drawn using various symbols 1 DS6S1-EB/Jun.1966Copyright 1966 by ASTM International www.astm.org to indicate annealed,normalized,cas
14、t,etc.These proc-essing or condition classifications are very broad and are intended to serve only as a guide in using the figures.The detailed processing,heat treatment,and composition data for each steel are given in the data sheets.Each figure includes the numbers of the appropriate data sheets f
15、or easy reference.Since the classification annealed,for example,includes different annealing temperatures,it is recommended that the data sheets be referred to when using the graphs.Whenever possible,the average data curves from DS 6 have been included in the figures to facilitate comparison of the
16、data.Acknowledgments The authors wish to thank the contributing organiza-tions and their representatives for taking the necessary time and trouble to supply the data upon which this publication is based.We also wish to thank the Data and Publications Panel and the Project Committee for their helpful suggestions and counsel in collecting and preparing the data for publication.Members of the Project Committee:C P.Weigel,chairman W.E.Leyda W.F.Simmons Members of the Data and Publications Panel:E.P.
