Hardening:Heat to 840 o C - 875 o C, hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.*Temper immediately while still hand warm. Nitriding:4140 hardened and tempered bar can also be successfully nitrided, giving a surface hardness of up to Rc 60. Nitriding is carried out at 490 o C - 530 o C 4140 Prehard Alloy Steel Flat Bar & Plate Key Metals Online4140 heat treated alloy is a chromium-molybdenum, medium carbon alloy steel, and is used in a wide variety of applications requiring high strength and toughness. The chromium imparts good hardness penetration while molybdenum provides hardness uniformity and strength.

AISI 1045 Steel Double Eagle Alloys

AISI 1045 is a medium carbon steel containing approximately 0.45% carbon that can be hardened by heat treatment to a maximum surface hardness of approximately Rockwell C 54-60 after flame or induction hardening. AISI 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.

Hardness and Tensile Strength of Steels:Brinell and Rockwell Scales Following is an estimate of the relationship between various hardness scales and the tensile strength of standard steels. It should be considered as a general comparison not applicable to all materials: Heat Treating 4140 steel FAQ :anvilfire How-to.Hammer Die Hardness:Stormcrow, the steel used and the heat treat are somewhat shape dependent on power hammer dies. 1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use. Is mid-30's Rockwell too hard? - Practical MachinistJun 26, 2009 · What Rockwell hardness value do you wish on your finished part? Is there a reason you are using pre-hardened 4140 or 4130? Another tool steel may be a better choice for your desired result. If not and you must use pre-hardened 4140/30 at 30 or 35 Rc why not just leave it at 30/35 Rc? Is that not hard enough for the application?

SAE-AISI 1018 Steel vs. SAE-AISI 4140 Steel ::MakeItFrom

May 30, 2020 · Both SAE-AISI 1018 steel and SAE-AISI 4140 steel are iron alloys. They have a very high 98% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown. Through-Hardening Low Alloy Steel Bar 4340Steel Bar 4340 Surface Hardening Nitriding Nitride at approximately 510°C for 10 to 60 hours, depending upon required case. Surface hardness achievable is 600 to 650HV. Induction or Flame Hardening Atlas 4340 can be surface hardened to 58HRC (water quench) or surface hardened to between 53 to 55HRC (oil quench). Tempering at 200°C. Welding Wingate Alloys Inc.4140 PREHARD is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 40. 4140 HT is supplied in many forms such as hot rolled or turned, ground and polished rounds and DCF plate to be used as a holder material for high strength structural components.
