Alloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel.
You are using the best pretreatment process for 4340 steel. Electro etching with sulfuric is an excellent method to remove any carbon smut from high carbon steels, like 4340, and provide a clean surface for adhesion. Nickel strike is a good insurance step.
Alloy Steel 4340, also referred to as AISI 4340, is a nickel, chromium, and molybdenum alloy steel. This heat treatable alloy is known for its toughness and high strength in a heat treated condition. It is weldable by both fusion and resistance welding, and offers good ductility in the annealed condition. You will find Alloy Steel 4340
Alloy Plate 4140 / 4340 / 8620 ASTM A 829 Standard specification for Alloy Steel Plate Furnished to Chemical Composition Requirements. ASTM A 829 was first issued in 1984; prior to that these grades were defined by AISI specifications.

Prior to WeldingLocate the slide plate base in the appropriate position on the existing steel surface. Place a protective covering on the graphite. Where seal welding is not required, follow the diagram shown which indicates 1/8” thick fillet weld, 1” long every 4” around entire perimeter of the base.
As mentioned above, pre hardened and tempered 4340 steel bars or plates can be further surface hardened by either the flame or induction hardening methods resulting in a
Nov 16, 2015 · When a higher strength part is welded to a lower strength carbon steel, the filler metal should be a low hydrogen type that matches the lower strength material. To prevent major welding problems when welding heat treatable steel, you must use proper preheat and interpass temperatures to eliminate or reduce cracking.
Alloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E 4340.
