SAE AISI 4340 Steel Properties, Heat Treatment,

Welding of AISI 4340 Steel. AISI 4340 steel has good weldability. It can be easily gas or arc welded, but electrodes of the same composition should be used. Since 4340 alloy steel is air hardened, the welded parts should be either annealed or normalized and tempered shortly after welding. AISI 4340 Alloy Steel (UNS G43400) - AZoMSep 07, 2012 · AISI 4340 alloy steel can be cold worked using all conventional methods in the annealed condition. It has high ductility. Annealing. AISI 4340 alloy steel is annealed at 844°C (1550°F) followed by cooling the furnace. Tempering. AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering.

Welding in the nitrided or flame or induction hardened conditions is not recommended. Welding with low-hydrogen electrodes and a preheat from 400 570ºF (200 300º C,) to be maintained during welding. Parts should be slow cooled after welding in glass wool or asbestos cloth blanket. 1. Qualify the base mAircraft Alloy Steel AISI 4340 / E-4340 - Aircraft Materials1.65-2.00. 0.20-0.30. Alloy E 4340 is a widely used deep-hardening constructional steel. Due to E-4340's high alloy content it obtains a uniformed hardness by heat treatment. The high fatigue strength makes E4340 ideal for highly stress parts as it maintains it's strength and hardness at elevated temperatures. AISI 4340 (E4340) per AMS 6359 - PlateMaterial may also meet specs ASTM-A829, AMS-2301, EN10204.

RE:AISI 4340 nitride AISI 4340 Steel W-Nr. 1.6511 DIN 36CrNiMo4 - OTAI AISI 4340 alloy steel is annealed at 844°C (1550°F) followed by cooling the furnace. Tempering; AISI 4340 alloy steel heat treated or normalized and heat treated condition before tempering. Tempering temperatures depend upon the desired strength level. Hardening; AISI 4340 alloy steel can be hardened by cold working or heat treatment. 11706 E4340 4340 ALLOY Metals Castle Metals SiteIn addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E-4340. E-4340 is critical for parts in aerospace and other industries where great strength is needed. The annealing of Alloy E-4340 characterizes the grade as containing excellent impact and strength properties with good eFunda:Properties of Alloy Steel Alloy Steel AISI 4340AISI 4340. Conditions.
