4140HW Alloy Steel Technical Data

Yield strengths range from 110 ksi through 140 ksi, but we can temper it to. other strength levels. When compared with standard 4140 heat treated to. the same tensile and yield strengths, 4140HW achieves significantly higher. toughness, as measured by impact strength (see Figure 9).4140 HIGH TENSILE STEEL - interlloy, astm 4140 hardness range.au4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting , astm 4140 hardness rangeAISI 4140 Alloy Steel (UNS G41400)AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. Tempering. AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature.
