8740 Alloy round steel

Product Introduction

8740 Alloy round steel

This alloy is forged at a starting temperature of around 2200oF and can be forged as low as 1700oF(925oC).

After forging, the alloy should be slowly cooled, but it can also be transported to a furnace at a temperature close to the forging finishing temperature, soaked, and air-cooled.

A microstructure consisting of coarse lamellar pearlite to coarse spheroidite is regarded as ideal for this alloy’s machinability. Austenitizing at 1525oF, furnace cooling to 1340oF, then cooling to 1180oF at 20oF/hr can produce such a structure. An iso-anneal at 1225°F is another option.

AISI 8740 | UNS# G87400 is roughly equal alloy steel to AISI 4140. This alloy is being used in applications that require a high level of strength, hardness, and wear resistance. It’s extensively utilized as forged fasteners with great strength.

If you are one that requires this alloy steel material, we guarantee that you will receive the best 8740 Alloy bar stocks and 8740 Alloy round bar stocks that meet your requirements.
