Typical Properties. AISI 4140 and 4150 is a medium carbon, chromium-molybdenum alloy steel. This steel is offered in a wide range of conditions including but not limited to:cold drawn annealed, hot roll heat treated, heat treated turned ground and polished. 4140 Steel Plate Precision Grinding, Inc.4140 steel has good machinability when annealed. 4140 steel is not easily welded and post weld treatment should be performed. This steel can be formed using conventional techniques when annealed. However, more pressure is required when forming because it is tougher than plain carbon steels.
Low alloy 4130:ASTM A29 (VO1.05) General scope . AISI 4130 low alloy steel containing nominally 0.3% Carbon, 1% Chromium and 0.2% Molybdenum is widely used in oil patch applications. It is similar to 4140 which has a higher carbon level giving 4130 improved weldability, at the expense of through thickness strength. AISI 4140 Alloy Steel (UNS G41400) - AZoMAISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition. Annealing. 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. AISI 4140 Alloy Steel (UNS G41400) - theenzoneAISI 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 lower tempering temperature. For example, tensile strength of 225 ksi

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.
