Forming of AISI 4130 steel can be performed in the annealed condition. Welding of AISI 4130 steel can be performed by all commercial methods. Heat Treatment - AISI 4130 steel is heated at 871°C (1600°F) and then quenched in oil. This steel is usually heat-treated at temperatures ranging from 899 to 927°C (1650 to 1700°F).SAE AISI 4130 Chromoly Steel, Alloy Material Properties , 4130 steel rockwell hardnessAISI 4130 steel (UNS G41300), also known as 4130 Chromoly steel, is a chrome-molybdenum series low alloy steel with high strength, toughness and hardenability, usually used in

It is typically used in structural applications, including gears, fasteners, and some aircraft exterior.AISI 4130 Steel, normalized at 870°C (1600°F)A very common general purpose grade of medium carbon, Cr-Mo steel. Flexibility afforded by heat treatment options allows it to attain a range of toughness and strength values. Good hardenability, strength, wear resistance, toughness, and ductility.
AISI 4130 Steel, 25CrMo4, 1.7218, 708A25, SCM430. AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, Alloy Steel 4130 - Wingate Alloys Inc.See more on wingatealloys, 4130 steel rockwell hardnessheat treating 4130 steel - Metal and Metallurgy , 4130 steel rockwell hardnessFeb 25, 2005 · RE: heat treating 4130 steel. 23 Feb 05 14:25. Your austenitizing temperature of 1600 deg F is ok, the furnace soak at temperature should only be 30 minutes ( at 1600 deg F for 30 minutes) not 2 hours. Immediately quench in oil (this is most important to perform as rapidly as possible).Two questions; 1. Where and how did you perform the hardness testing? 2. Did the furnace contain a protective (reducing) or inert atmosphere to pre, 4130 steel rockwell hardnessI was in our lab. We have a rockwell hardness tester. Yes, it did. I meant 4130 not 4103I would suggest you remove a sample and have a metallographic examination performed to verify your heat treatment process.

Tensile specimens for 1/2 and 1 rounds are taken from the centers of the bars. Specimens for 2 and 4 rounds are taken from the half-radius position, as is con- ventionally required by most specifications.
