CAST STEEL SHOT
1990-03-01
HISTORICAL
J827_199003
This SAE Recommended Practice describes chemical analysis, hardness, microstructure and physical characteristic requirements for cast steel shot to be used for shot peening or blast cleaning operations.

DEFINITIONS FOR MACROSTRAIN AND MICROSTRAIN
1985-08-01
HISTORICAL
J932_198508
In the analysis and measurement of residual stresses of materials, it has been noted that there are frequently differences in interpretation of the terms "macrostrain" and "microstrain." To assist communication among research personnel in this area, definitions for these two terms are suggested by the Fatigue Design and Evaluation Committee of SAE. Since "macrostress" is commonly computed from "macrostrain" in residual stress analysis, to be consistent, the definitions given are for "macrostrain" and "microstrain."

METALLIC SHOT AND GRIT MECHANICAL TESTING

PROCEDURES FOR USING STANDARD SHOT PEENING TEST STRIP
1984-01-01
HISTORICAL
J443_198401
This SAE Recommended Practice provides uniform procedures for using the standard shot peening test strips reported in SAE Standard J442, Test Strip, Holder and Gage for Shot Peening. Standard test strips are used to control repeatability of the shot peening machine operations, and to specify a desired result on a part. It is recommended that the standard test strip A be used for intensities that produce arc heights of 6A to 24A. For intensities below 6A, the standard N strip is recommended, and for intensities above 24A, the standard C strip is recommended. Shot peening is intended to induce surface compressive stresses in metal parts for the purpose of improving resistance to fatigue and stress corrosion cracking. Springs, axles, and aircraft landing gears are typical examples of such parts.

SAE MANUAL ON BLAST CLEANING
1968-06-01
HISTORICAL
J792A_196806
Blast cleaning may be defined as a secondary manufacturing process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece. As indicated in the definition, blast cleaning may be employed for a variety of purposes. Ordinarily, it is considered as a method for removing sand from castings, burrs or scale from forgings, mill products, or heat treated parts; to promote machinability, and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces an excellent surface for industrial coatings. All these objectives are often accomplished in the one operation.

SURFACE TEXTURE CONTROL
1963-06-01
HISTORICAL
J449_196306
SAE J448, Surface Texture, has been set up for precision reference specimens using a controlled surface profile to obtain reproducible roughness values. These specimens are for instrument calibration. Appropriate symbols for roughness, waviness, and lay have also been standardized (ASA B46.1-1962 and SAE J448). For production control, especially from one geographical location to another, means are required to facilitate the inspection of surface characteristics called for by specifications which include not only roughness but profile waviness and lay. In order to integrate the requirements of the designer with the actual production of surfaces, a second grade of control standards must be adopted which will be functional in nature for the specific product being manufactured. These control standards may be Calibrated Pilot Specimens (actual parts with satisfactory texture) or Roughness Comparison Specimens (ASA B46.1-1962).

SURFACE TEXTURE
1963-06-01
HISTORICAL
J448A_196306
This SAE Standard is concerned with the geometrical irregularities of surfaces of solid materials. It establishes definite classifications for various degrees of roughness and waviness and for several varieties of lay. It also provides a set of symbols for use on drawings, and in specifications, reports, and the like. The ranges for roughness and waviness are divided into a number of steps, and the general types of lay are established by type characteristics. This standard does not define what degrees of surface roughness and waviness or what type of lay are suitable for any specific purpose. It does not specify the means by which any degree of such irregularities may be obtained or produced. Neither is it concerned with the other surface qualities such as luster, appearance, color, corrosion resistance, wear resistance, hardness, microstructure, and absorption characteristics any of which may be governing considerations in specific applications.
