Solders

Metals Technical Executive Steering Committee
  • Ground Vehicle Standard
  • J473_201808
  • Current
Published 2018-08-24 by SAE International in United States
The choice of the type and grade of solder for any specific purpose will depend on the materials to be joined and the method of applying. Those with higher amounts of tin usually wet and bond more readily and have a narrower semi-molten range than lower amounts of tin. For strictly economic reasons, it is recommended that the grade of solder metal be selected that contains least amount of tin required to give suitable flowing and adhesive qualities for application. All the lead-tin solders, with or without antimony, are usually suitable for joining steel and copper base alloys. For galvanized steel or zinc, only Class A solders should be used. Class B solders, containing antimony usually as a substitute for some of the tin or to increase strength and hardness of the filler metal, form intermetallic antimony-zinc compounds, causing the joint to become embrittled. Lead-tin solders are not recommended for joining aluminum, magnesium, or stainless steel. Permissible impurity levels are shown: In dipping solders, 0.5% max copper is permissible because of pickup in bath. Compositions,…

Sintered Powder Metal Parts: Ferrous

Metals Technical Executive Steering Committee
  • Ground Vehicle Standard
  • J471_201808
  • Current
Published 2018-08-24 by SAE International in United States
Powder metal (P/M) parts are manufactured by pressing metal powders to the required shape in a precision die and sintering to produce metallurgical bonds between the particles, thus generating the appropriate mechanical properties. The shape and mechanical properties of the part may be subsequently modified by repressing or by conventional methods such. as machining and/or heat treating. While powder metallurgy embraces a number of fields wherein metal powders may be used as raw materials, this standard is concerned primarily with information relating to mechanical components and bearings produced from iron-base materials.

Special Purpose Alloys ("Superalloys")

Metals Technical Executive Steering Committee
  • Ground Vehicle Standard
  • J467B_201802
  • Current
Published 2018-02-15 by SAE International in United States
The data given in Tables 1–4 are typical values only and are not intended for design parameters. Mechanical properties of the special purpose alloys depend greatly upon processing variables and heat treatment. It is recommended that design data be obtained by actual testing or by consultation with the producers of the alloys.

Wrought Nickel and Nickel-Related Alloys

Metals Technical Executive Steering Committee
  • Ground Vehicle Standard
  • J470_201802
  • Current
Published 2018-02-15 by SAE International in United States
This Report presents general information on over 50 alloys in which nickel either predominates or is a significant alloying element. It covers primarily wrought materials, and is not necessarily all inclusive. Values given are in most cases average or nominal, and if more precise values are required the producer(s) should be contacted. This report does not cover the so-called "superalloys," or the iron base stainless steels. Refer to SAE J467, Special Purpose Alloys, and SAE J405, Chemical Compositions of SAE Wrought Stainless Steels, respectively, for data on these alloys.

Hardness Tests and Hardness Number Conversions

Metals Technical Executive Steering Committee
  • Ground Vehicle Standard
  • J417_201801
  • Current
Published 2018-01-10 by SAE International in United States
This report lists approximate hardness conversion values; test methods for Vickers Hardness, Brinell Hardness, Rockwell Hardness Rockwell Superficial Hardness, Shore Hardness; and information regarding surface preparation, specimen thickness, effect of curved surfaces, and recommendations for Rockwell surface hardness testing for case hardened parts. The tables in this report give the approximate relationship of Vickers Brinell, Rockwell, and Scleroscope hardness values and corresponding approximate tensile strengths of steels. It is impossible to give exact relationships because of the inevitable influence of size, mass, composition, and method of heat treatment. Where more precise conversions are required, they should be developed specially for each steel composition, heat treatment, and part. The accompanying conversion tables for steel hardness numbers are based on extensive tests on carbon and alloy steels, mostly in the heat treated condition, but have been found to be reliable on practically all constructional alloy steels and tool steels in the as-forged, annealed, normalized, and quenched and tempered conditions, provided they are homogeneous. Such special cases as high manganese steel, 18% chromium— 8% nickel steel and other…

  • Ground Vehicle Standard
  • J836_201801
  • Current
Published 2018-01-10 by SAE International in United States

This report is an abbreviated summary of metallurgical joining by welding, brazing, and soldering. It is generally intended to reflect current usage in the automotive industry; however, it does include some of the more recently developed processes. More comprehensive coverage of materials, processing details, and equipment required may be found in the Welding Handbook, Soldering Manual, and other publications of the American Welding Society for Testing and Materials. AWS Automotive Welding Committee publications on Recommended Practices are particularly recommended for the design or product engineer. This report is not intended to cover mechanical joining such as rivets or screw fasteners, or chemical joining processes such as adhesive joining.
