Plymouth ProMoly®
Plymouth ProMoly® 4130 Cold Drawn Seamless Tubing is a steel grade containing the alloy elements of chromium and molybdenum to help achieve desirable strength levels to meet your needs. The consistency of the OD and wall makes set-up easier and minimizes set-up variation. The proprietary controls of the annealing process offer welders the benefit of a surface finish with minimal decarburization and oxidation, reducing weld area preparation time. These controls also provide a consistent product from heat lot to heat lot, year after year.
