the columns for Minimum Tensile Strength, ksi and Minimum Yield Strength, ksi in the U.S Customary edition tables of Section II, Part D (b) List the values from the Metric edition of the material

YIELD STRENGTH TREND CURVES FOR ALL SITUATIONS IN WHICH THE MINIMUM RT SPECIFIED VALUES IN ONE UNIT SYSTEM ARE NOT PRECISE CONVERSIONS OF THE UNITS IN THE OTHER SYSTEM ONE MATERIAL HAS ONE TREND CURVE RULE This rule requires that the trend curves in either system of units are precisely congruent with one another That is, if the Metric and U.S Customary curves are placed on top of one another, they appear to be only one curve Thus, a material does not have two trend curves of the same shape, but has one curve shifted up or down because of slight differences between the U.S Customary and Metric RT specified values It should be recognized that following the “one material: one trend curve” rule will result in certain inconsistencies with the criteria established by Mandatory Appendices 1, 2, and 10 of Section II, Part D The rule was first established when the Section II-D tables were metricated An example of the inconsistency with SPECIFICATION EXISTS IN ONLY ONE SET OF UNITS When a specification exists for only one set of units (common for EN and other non-U.S specifications for which only Metric editions exist), the following: (a) Specification Exists Only in U.S Customary

can be seen in the Metric values for Type 347H stainless steel, on pp 102–105 of the 2010 Edition, 2011 Addenda of Section II, Part D Metric Inspection of Line No on these pages, for SA-312 seamless pipe, shows that the values in the Min Tensile Strength and Min Yield Strength columns on p 103 are, respectively, 515 MPa and 205 MPa, as they appear in the SA-312 specification in Section II, Part A However, the value in the −30 to 40°C and the 65°C columns, 138 MPa, is not equal to either 515/3.5 = 147.14 = 147 MPa or (205 × 2)/3 = 136.67 = 137 MPa Instead, 138 MPa is obtained from (30 ksi × 6.894757 × 2)/3 = 137.89514 = 138 MPa In this example, the “one material: one trend curve” rule results in a value at two temperatures that is slightly higher than would have been obtained from applying the Appendix criteria to the Metric minimum specified yield strength For other materials, slightly lower values might result However, in either example, the values will be identical (within rounding variances) to those of the U.S Customary values at the same temperatures D-230 When a non-ASTM specification that, in the judgment of the Committee, has chemistry and heat treatment requirements so similar to an ASTM specification and grade that is already listed in Section II, Part D, that it is indistinguishable from the ASTM material, the Committee may choose to use the same trend curves for the nonASTM specification as were used to develop the values for the ASTM material, regardless of any differences between the U.S Customary minimum specified values and the Metric minimum specified values D-300 D-310 D-220 EQUIVALENT MATERIALS ANCHORING THE TREND CURVE SIGNIFICANT FIGURES IN THE ALLOWABLE STRESS TABLES U.S CUSTOMARY TABLES When listing allowable stress values

D-320 METRIC TABLES When listing allowable stress values in MPa, the last step in the analysis is to round the calculated values to three significant figures, except that, for values greater than 999 MPa, round the value of the fourth figure to or For example, 1022 rounds to 1020, while 1023 rounds to 1025 MPa 974 This copy downloaded on 2015-07-13 07:19:51 -0500 by authorized user logan ahlstrom When anchoring the yield and tensile strength trend curve, the U.S Customary tensile and yield strengths are used when the specification is either a dual unit specification or exists only in U.S Customary units The Metric trend curve is then anchored to the conversion of the U.S Customary values — the U.S Customary values multiplied by 6.894757 Rounding is delayed until the last step (see D-300) However, when the specification exists only in a Metric version, the U.S Customary trend curves are anchored to the soft conversion from the Metric-specified minimum tensile and yield

ASTM definition of ferrous alloy: an alloy whose major constituent is iron, even if the iron content is less than 50% of the total composition However, this is a recently adopted definition and the change to specifications is occurring over time Therefore, some alloys that were formerly defined as nonferrous are still listed in the nonferrous tables or both This chart is used only for this condition and is only applicable to uniform external pressure This applies to unstiffened cylinders Since most materials are, in many applications, used in components that operate under compressive loads, the Committee recommends that stress–strain plots as described above should always be included in the data package submitted in support of the application for any new material The term minimum yield strength, as used here, means the yield strength values that are derived from the analysis of the tensile data required elsewhere in this Mandatory Appendix Modulus of elasticity values shall be
