Organization: ASTM
Publication Date: 30 July 1982
Status: inactive
Page Count: 6
scope:

This practice includes reference photographs and descrjptions that illustrate various types and degrees of surface roughness and surface discontinuities that may occur in steel castings. They are intended to provide the following:

A guide enabling recognition of discontinuities and their differentiation upon visual examination as to type and severity.

Sets of graded reference photographs and descriptions from which purchasers and suppliers may, by mutual agreement, select visual examination standards of surface acceptability.

The surface roughness and discontinuities listed below are included in this practice. Verbal descriptions of discontinuities are presented in the adjunct2 , with illustrations where a photo series is not applicable for rating their severity (Section 3).

Surface Texture.

Linear Discontinuities - Hot tears and cracks.

Shrinkage:

Shrinkage in reentrant angles (comers) and edges.

Shrinkage under risers and gates, and

Shrinkage revealed by machining.

Nonmetallic Inclusions:

Sand inclusions.

Slag inclusions, and

Ceroxide inclusions.

Gas Porosity

Scattered porosity.

Aligned porosity, and

Clustered porosity.

Expansion Discontinuities:

Veins,

Rat tails, and

Scabs

Fusion Discontinuities:

Wrinkles.

Laps, folds, and cold shuts, and

Misruns.

Metal Removal Marks:

Flame cutting,

Air carbon-arc cutting.

Abrasive cut-off, and

Sawing, grinding, chiselling.

Inserts - Chaplets and internal chills.

External Chills:

External chills,

Brackets, and

Fins

Welding:

Undercut, and

Weld spatter.

This standard may involve hazardous materials, operations. and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
