ASTM A829-4140 Quenched & Tempered Steel Plate refers to alloy steel plates conforming to the ASTM A829 standard, specifically grade 4140, that have undergone quenching and tempering heat treatments to achieve enhanced mechanical properties.
4140 steel is a versatile chromium-molybdenum alloy steel, also recognized under designations such as AISI 4140 and SAE 4140. These designations are largely interchangeable, all referencing the same material composition as defined within ASTM A29. Common equivalents include DIN 1.7225, 42CrMo4, EN 19, and JIS SCM440.
The quenching and tempering process involves heating the steel to a high temperature followed by rapid cooling (quenching) and then reheating to a lower temperature (tempering). This treatment significantly improves the steel’s strength, hardness, and toughness. For light sections like 4140 PH steel plate, hardness levels can reach 28-32 HRC, while heavier sections typically achieve 22-27 HRC after quenching and tempering.
