    Feb 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 prebest 4130 steel hardeningI 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. This examination will debest 4130 steel hardeningI was looking for the proper times and tempatures for this process. I have the certs that it is 4130.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 2best 4130 steel hardeningThank you, I'll try this tomorrow.I'd say that a 700F temper is a tad high for your required hardness. I would suggest 450F for one hour.Instead of quessing you can use MIL-H-6875 which can be found at http://assist.daps.dla.mil/quicksearch/An additional source of this data - not free however - is the ASM Handbook Volume 4 Heat Treating.

    Nov 28, 2011 · 4130 has a machinability rating of about 35%, meaning your speed will be about 1/3 that of mild steel. Using carbide try about 100 SFPM and HSS about 30 SFPM. 38Rc is not a problem with carbide, might have to run slower. 4130 hardens about 1" deep so if you have cross sections exceeding that you should rough machine before HT.See more results

    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, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum.

  7. How to Harden 4140 Steel, eHow

    4140 is relatively easy to harden. Hardening steels involves the basic process of heating the steel to organize the crystalline structure in a uniform way and then rapidly cooling it by quenching it to lock the molecular make-up of the steel. However, different steels have different hardening steps to follow.
