1. Name the microstructural products of 4340 alloy steel

May 10, 2021 · 1. Name the microstructural products of 4340 alloy steel specimens that are first completely transformed to austenite, then cooled to room temperature at the following rates:(a) 0.005°C/s (b) 0.05°C/s (c) 0.5°C/s (d) 5°C/s 2. Briefly describe the simplest continuous-cooling heat treatment procedure 4340 (E4340) Alloy Steel, AISI 4340, Plate, Round Bar AQ AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for its toughness and strength. Machining is done typically in the annealed condition. 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 steel from stock.

4340 alloy steel bar is used heavily in the aerospace industry due to its ultra-high strength. When heat treated it is known for its toughness while preserving good fatigue strength. For highly stressed parts it is excellent choice. It can be machined by all customary methods. 4340 Alloy Steel Material DatasheetAISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for providing a good balance between strength and malleability. Alloy 4340 is composed of (descending in order by weight):iron, nickel, chromium, manganese, carbon, molybdenum, silicon, phosphorus and sulfur. With proper working and strengthening, items made from 4340 have excellent wear and durability qualities. AIS 4340 Low Alloy SteelA low alloy steel containing chromium, nickel and molybdenum, AISI 4340 demonstrates extraordinary toughness and strength in the heat-treated condition. With high ductility, it can be bent or formed by pressing or spinning in the annealed state. AISI 4340 is often used in power transmission gears and shafts along with other structural parts.
