    AISI 4140 also known as EN19 comes treated in the annealed as rolled or even T condition. We can offer AISI 4140 in bar form from stock, rolled and bright drawn. It is renown for its wear resistance and where high strength properties is required. Suitable for gears, shafts, spindles, etc. Frequently used within the gas and oil industry. For improved weldability consider using 4130.
    The 41xx family of steel include chromium and molybdenum and are often referred to as chromoly steel or chrome-moly. Chromoly steels have an excellent strength to weight ratio but do not contain sufficient quantities to provide the levels of corrosion resistance found in stainless steels. These steel are often used in aircraft parts also frequently used within the gas and oil industry.
