4140HW Alloy Steel Technical Data

4140HW Alloy Steel Technical Data 4140HW meets AISI4140 standards and has improved hardenability and strength in heavier cross-sections. Alloy Description TimkenSteels 4140HW grade is a fine-grained, low-alloy steel that offers optimum heat-treat response in heavier cross-sections. You find 4140HW in a AISI 4140 Alloy Steel (UNS G41400) - AZoMAISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed. Heat Treatment. AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil.

Encore Metals - 4140/4142

Alloy AISI/SAE 4140/ 4142 (UNS G 41400/G 41442) Mechanical Properties Heat treated to HRC 22 maximum for sour gas service. Minimum tempering temp 1150 F. Conforms to NACE Standard MR01-75. How To Weld 4140 Steel WELDING ANSWERSAISI 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel. The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a lot stronger and harder than standard 1018 and 1020 steels.
