En19 Alloy Steel for Use in The Machine Tool and Motor Industries

EN19 Steel, also known as 42CrMo4 or 1.7225, is a high tensile steel that is widely used in the manufacturing of heavy-duty gears, automotive components, crankshafts, and other mechanical parts. It belongs to the alloy steels category and is characterized by its excellent strength, toughness, and wear resistance.

EN19 steel is primarily composed of chromium, manganese, molybdenum, and carbon. The addition of these alloy elements enhances its mechanical properties, such as high tensile strength and hardenability. This steel can be heat treated to achieve different hardness levels, making it suitable for a variety of industrial applications.

The chemical composition of EN19 steel typically includes 0.38-0.45% carbon, 0.50-0.80% manganese, 0.90-1.20% chromium, 0.15-0.30% molybdenum, and small amounts of other elements like silicon, phosphorus, sulfur, and vanadium.

EN19 steel has excellent fatigue resistance and impact strength, making it suitable for heavy-duty and high-stress applications. It also exhibits good wear resistance, which allows it to withstand abrasive conditions. EN19 steel can be machined and welded, although preheating and post-weld stress relief may be required to avoid cracking.

In summary, EN19 steel is a high tensile alloy steel with excellent mechanical properties. It is commonly used in applications that require strength, toughness, and wear resistance, such as gears, crankshafts, and automotive components. Its versatility and durability make it a popular choice in various industries.

Grade Introduction:
EN19 Steel is a high-quality engineering alloy steel containing chromium and molybdenum. It falls in a class of low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsion strength. It can be heat treated in a number of ways to give it a combination of properties. EN19 Steel is one steel grade in BS 970-1955 standard, which is the specification for wrought steels for mechanical and allied engineering purposes. Although there is a new version of BS 970-1996 latest edition. And EN19 steel grade is similar to the 709M40 grade in the new version.  EN19 Alloy Forging Steel.
Grade Application:
EN19 Alloy steel was originally introduced for use in the machine tool and motor industries for gears, pinions, shafts, spindles, and the like. Later its applications became much more extended and it is now widely used in areas such as the oil and gas industries. EN19 is suitable for applications such as gears, bolts, studs, and a wide variety of applications where a good quality high tensile steel grade is suited.
