4130 Chromoly Bar

4130 Chromoly is often used when additional strength and tighter tolerances are needed. The word chromoly is derived from the combination of chromium and molybdenum which are two of its main elements. The additional chromium increases the strength (hardenability) and corrosion resistance in the material. The molybdenum makes it tougher.AISI 4130 – Alloy steel grade 4130.
