4130 – Steel
Our Modified 4130 Alloy Steel Provides Good Weldability Without Compromising Impact Resistance
At Sunbelt Steel, we offer a deep inventory of highly specialized grades of alloy and carbon steel. Our varied stock of steel is perfect for an array of drilling applications whether down-hole or top-side. And with our Sure Bar™ promise, you can rest assured that ours is a stock of steel you can count on.
Our vast inventory includes alloys such as 4130, a low-alloy steel strengthened by chromium and molybdenum. This material ensures good strength, and its low-carbon composition allows for good weldability. It is also readily machinable through conventional methods. 4130 alloy steel’s strength is accompanied by a good resistance to atmospheric corrosion and an overall combination of fatigue strength and toughness.
4130 is a versatile allow that has found many applications in both the aerospace and oil and gas industries and has even been used in agriculture and defense industries. Its good mechanical properties are obtained by normalizing where the required strength isn’t too high.
