304L Stainless Steel Drill Rod
304L drill rod is precision ground which saves time and money in part making. 304L stainless steel is the most commonly used stainless steel grade. It is a grade that’s often purchased as a 304/304L dual certified stainless. 304L stainless is a very low carbon, austenitic chromium-nickel steel with high malleability plus good corrosion resistance and superior resistance to intergranular corrosion following welding or stress relieving. The low carbon content in 304 stainless steel limits the formation of harmful carbides to such an extent that this grade may be safely used for most operations of welded construction, as well as where the service temperature is limited to 800 degrees F. As noted above 304L Stainless Steel is austenitic so it is not magnetic in the annealed condition and not hardenable by heat treatment.
Alro stocks 304L stainless steel in many shapes including: drill rod, tubing, angles, beams, bars, channels, coils, pipes, plates, tubing, and sheets.
Comparing Types of Stainless Steel
Stainless Steel 304 vs. Stainless Steel 304L
The only difference between 304 steel and 304L steel is the carbon content of each grade. While all 304 stainless steel is low carbon, 304 has a roughly 0.04% higher carbon content maximum than 304L. For large weldments, 304L’s lower carbon content can help prevent possible corrosion caused by chromium depletion at high temperatures.
Stainless Steel 304 vs. Stainless Steel 316
Because 304 and 316 steel are the first and second most common stainless steel grades, respectively, they naturally draw comparisons. The main difference between the two is that 316 steel contains molybdenum. Molybdenum makes 316 more corrosion resistant and therefore more suitable for high acidity environments and applications, like underwater equipment, surgical tools, and pharmaceutical production. However, 304 steel tends to be more affordable, allowing for versatile application in environments where extreme oxidation is less of a risk.
