Carbon Steel Round Bar – C15Carbon Steel Round Bar is plain steel with a nominal 0.15% carbon content. It is low strength steel but it may be quenched and tempered for increased strength. The low carbon steels, such as C15 are used for applications such as cold headed fasteners and bolts.

Carbon Steel Round Bar – C20Carbon Steel round bar C20 is an unalloyed low carbon mild steel grade supplied as a hot rolled or bright drawn finish bar. As a low carbon grade, it provides low strength with good machinability and is suitable for welding. Lightly stressed in the form of bolts, fixings, shafts, spacers, hubs, and bushings. Bracketry, linkages, and base plates would be fine to produce using carbon steel EN3.

Carbon Steel Round Bar – C30Step Shaft: steel plate/sheet,coil,round bar,flat bar,tube/pipe,Profiled forgings. C30 steel, steel plates, C30 steel sheet, is a kind of high carbon steel plates, steel sheets in EN10250 standard.

Carbon Steel Round Bar – C40It is a medium Carbon Steel which is similar to low carbon steel except that the carbon ranges from 0.30 to 0.60% & the manganese from 0.50 to 1.65%. Increasing the carbon content is approximately 0.5% with an accompanying increase in manganese allows medium carbon steel to be used in the quenched & tempered conditions.

Carbon Steel Round Bar – C45C45 is a medium carbon steel grade offering reasonable tensile strength. Supplied in the cold drawn or hot rolled condition, tensile properties can vary but are approximately between 500-800 N/mm². This grade can be flame or induction hardened to produce a good surface hardness with moderate wear resistance. C45 is widely used for components that require better properties than mild steel but does not justify the costs of alloy steel.

EN19 is a high-Quality alloy steel often used in applications requiring high strength and toughness. When referring to "EN19 forged round bars," you're talking about cylindrical bars made from EN19 steel that have been shaped through a forging process. Here's a detailed description:
### EN19 Forged Round Bar Description:
**Material**:- **Grade**: EN19 is also known as SAE 4140 or AISI 4140, and it is a chromium-molybdenum alloy steel.- **Composition**: Typically contains:  - **Carbon**: 0.38% - 0.43%  - **Chromium**: 0.80% - 1.10%  - **Molybdenum**: 0.15% - 0.25%  - **Manganese**: 0.75% - 1.00%  - **Silicon**: Up to 0.35%  **Properties**:- **Tensile Strength**: Typically ranges from 700 to 850 MPa (100,000 to 120,000 psi), depending on the heat treatment process.- **Yield Strength**: Generally between 450 and 600 MPa (65,000 to 87,000 psi) when properly heat-treated.- **Hardness**: Can achieve hardness levels of 28-34 HRC (Rockwell Hardness C) in its annealed state, and up to 50 HRC after heat treatment.- **Impact Toughness**: Excellent impact toughness due to its alloying elements and forged structure.
**Applications**:- **Automotive**: Used for high-strength components like crankshafts, gear shafts, and axles.- **Engineering**: Suitable for manufacturing heavy-duty machinery parts, such as gears, connecting rods, and forgings for structural applications.- **Aerospace**: Employed in parts requiring high strength-to-weight ratios and fatigue resistance.
**Manufacturing**:- **Forging Process**: EN19 steel is heated and then forged into round bars through processes like hammering, pressing, or rolling. Forging aligns the grain structure of the steel, enhancing its mechanical properties and strength.- **Form**: Supplied as round bars, which are cylindrical sections of steel used in various machining and manufacturing processes.- **Dimensions**: Available in a range of diameters and lengths. Common diameters range from a few millimeters to several inches, depending on application requirements.- **Heat Treatment**: EN19 round bars are often heat-treated to achieve desired properties. Common heat treatments include quenching and tempering to enhance hardness and toughness.
**Surface Finish**:- **Finish**: Typically has a mill finish, which may be rough or semi-rough. Additional machining, grinding, or polishing can be applied to achieve a smooth surface finish.- **Coatings**: Generally, coatings are not required due to the inherent properties of the alloy steel, though some applications might benefit from additional protective coatings to prevent corrosion.
**Standards and Testing**:- **Standards**: Conforms to standards such as EN 19 or equivalent specifications (e.g., ASTM A322).- **Testing**: Often subjected to testing for chemical composition, mechanical properties, and dimensional accuracy. Tests may include tensile tests, hardness tests, and impact tests to ensure quality.
**Advantages**:- **High Strength**: Provides excellent strength and durability, making it suitable for high-stress applications.- **Toughness**: Offers good toughness and resistance to impact and fatigue, enhancing performance in demanding conditions.- **Versatility**: Can be used in a wide range of applications due to its favorable mechanical properties and ability to be heat treated for specific requirements.
EN19 forged round bars are widely valued in industries where high strength, toughness, and reliability are critical. Their properties make them suitable for demanding applications in automotive, engineering, and aerospace sectors.

EN19 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. EN19 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.

Hot work tool steels are designated as group H steels, and they have 0.35% to 0.45% carbon, 6% to 25% chromium, with vanadium, molybdenum, and tungsten as the other alloying elements. Tungsten is primarily used in hot forming tool steels due to its high-temperature strength, toughness, and resistance to grain growth.

MS – BRIGHT BAR Grade Introduction:The term Mild Steel applies to all Brigh Bar Round  low carbon Steel that does not contain any alloying elements in its makeup and has a carbon content that does not exceed 0.25%. The term “Mild” is used to cover a wide range of specifications and forms for a variety of Steel. Mild Steel is used in mechanical engineering applications for parts that will not be subject to high stress. When in its bright cold drawn condition the steel is able to endure higher levels of stress, particularly on smaller diameters. but Compared to normal Mild Steel, bright Mild Steel provides tighter sectional tolerances, increased straightness, and a much cleaner surface. The main advantage of cold drawn steel is that Steel can be brought closer to the finished machine size, reducing machining costs. Another benefit of bright Steel bars is a marked increase in physical strength over hot rolled bars of the same section. Mild steel for industries of all sizes and our affordable products will prove to be a great asset for your enterprise. An alloy of carbon and iron is known as steel and the properties of steel are different according to its grade. For instance, the carbon content present in the steel bar can be anything, say 0.08 percent to 2 percent. Mild steel can be easily referred to as plain steel or carbon steel. so Usually it is quite durable and strong in its form. We ensure timely delivery of steel bars so that you can carry out your manufacturing without any hindrance. Mild steel comes in a wide range of grades and no matter which one you choose, you get the best quality. We manufacture all our steel grades whether alloy or mild, using “A grade” raw materials and we also do regular quality checks in order to ensure that each batch we deliver meets our standards. MS – BRIGHT BAR Grade Application:
