Steel with Cr., Mo.,Cr-Mo description
Steel with Cr., Mo.,Cr-Mo is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often referred to as chromoly steel, molybdenum steel or CRMO. They have an excellent strength to weight ratio, are easily welded and are considerably stronger and harder than standard 1020 steel.
While these grades of steel do contain chromium, it is not in great enough quantities to provide the corrosion resistance found in stainless steel.
Steel with Cr., Mo.,Cr-Mo Application
The applications for Steel with Cr., Mo.,Cr-Mo includes structural tubing, bicycle frames, firearms receivers, clutch and flywheel components, and roll cages. One of the grade 4150 stands out as being one of the steels accepted for use in M16 rifle and M4 carbine barrels by the United States military. These steels are also used in aircraft parts and therefore Steel with Cr., Mo.,Cr-Mo grade structural tubing is sometimes referred to as "aircraft tubing".
