How do I Compare 4140 & 4150 Steel? Sciencing

Mixing steel with various amounts of other elements produces steel alloys with mechanical properties superior to steel alone. SAE 4140 and 4150 steels are standard alloy steels. The major criteria used for comparing alloy steels are chemical composition and tensile strength.

How to Prepare for Welding 4140 Steel Career Trend

The carbon content of 4140 steel is 0.40 percent, making it a medium carbon steel. Choose your electrode. The electrodes in TIG can be pure tungsten for softer steels, but they may require alloying agents for harder steels. Grade 4140 steel is relatively hard and typically uses tungsten electrodes with 2 percent cerium oxide.

How To Weld 4140 Steel WELDING ANSWERS

AISI 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel. The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low alloy steel with excellent strength to weight ratio and make it a lot stronger and harder than standard 1018 and 1020 steels.

Basics of the North American Steel Grade System Carbon

The first 2 digits give us an idea about whether the grade is a plain carbon or alloy steel. See our post here. So 1018 is a plain carbon grade; 1137 is a resulfurized carbon steel; 4140 is an alloy steel. So lets look at those last two digits in the 4 digit AISI/ SAE grade designation, and what they mean in the carbon grades we see in our shops.
