4.1. Significance and Use

This specification covers pickled and oiled, hot-wrought, low carbon steel plate or heavy-thicknesscoils of sheet or strip.Current Release Number Std. Revision LevelPage 1 of 4003872963

This specification is applicable to material from 0.230 inches (5.85 millimeters) to 1.500 inches(38.10 millimeters) of



4.1. Significance and Use (Continued)thickness. Plate per ASTM A283 may be applied to all thicknesses. Heavy-thickness coils perASTM A635 may be applied up to 0.750 inches (19.05 millimeters).Material is intended to be used for parts which may required minimummechanical properties. Ma-terial can be fabricated by moderate cold bending with bend radii of one T or better, moderate hotforming, punching, and welding. Material is also suitable for general purpose machining.

Acceptance limits are statistically significant as indicated in CES 99020 unless specifically except-ed.
