SAE J404 Alloy Steel Bars are high-quality alloy steel bars defined by the SAE system for alloy steels used in structural and mechanical applications. These steels contain alloying elements such as chromium, nickel, molybdenum, and manganese that enhance strength, hardenability, toughness, and wear resistance compared to plain carbon steels. Manufactured in accordance with SAE J404, this specification establishes the chemical composition limits for SAE alloy steels used in semifinished products, hot-rolled bars, cold-finished bars, wire rods, plates, sheets, strip, welded tubing, and seamless tubing. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of SAE J404 Alloy Steel Bars, supplied with mill test certificates and strict quality inspection as per international standards. Forms of Supply (as per specification): Hot rolled round bars, Black bars, Bright bars, Cold drawn bars, Peeled bars, Turned bars, Ground bars, Forged round bars Available Grades (as per SAE J404): 1330, 1335, 1340, 1345, 4023, 4024, 4027, 4028, 4037, 4047, 4118, 4120, 4121, 4130, 4135, 4137, 4140, 4142, 4145, 4147, 4150, 4161, 4320, 4340, 4615, 4620, 4621, 4626, 4720, 4815, 4820, 5115, 5117, 5120, 5130, 5140, 5150, 5160, 52100, 6118, 6150, 8615, 8620, 8630, 8640, 8645, 8655, 8720, 8740, 8822, 9255, 9259, 9260 Explanation of SAE Designation: • The first digit indicates the principal alloying element • The second digit indicates the alloy series or modification • The last two digits represent the approximate carbon content in hundredths of a percent Typical Chemical Composition (varies by grade): • Carbon (C): As per grade designation • Manganese (Mn): Improves strength and hardenability • Chromium (Cr): Enhances wear resistance and corrosion resistance • Nickel (Ni): Increases toughness and impact strength • Molybdenum (Mo): Improves hardenability and high-temperature strength • Phosphorus (P) & Sulphur (S): Restricted to specified maximum limits Mechanical Properties (Typical – Grade Dependent): • High tensile strength • Excellent yield strength • Good fatigue resistance • Improved toughness • Hardness varies according to heat treatment condition Key Features: • Excellent hardenability • High strength and toughness • Good machinability in annealed condition • Suitable for carburizing and heat treatment • Reliable performance in heavy-duty applications Material Characteristics: SAE J404 alloy steel bars provide superior mechanical performance due to the presence of alloying elements such as chromium, nickel, and molybdenum. These steels are designed to perform well under high stress, impact, and wear conditions, making them suitable for demanding industrial applications. Applications: • Automotive gears and shafts • Crankshafts and axles • Heavy-duty fasteners • Industrial machinery components • Oil and gas equipment parts • Structural engineering components Conclusion: Ladhani Metal Corporation supplies high-quality SAE J404 Alloy Steel Bars in a wide range of grades, sizes, and finishes. With excellent strength, durability, and heat treatment response, SAE J404 steel bars are widely used in automotive, heavy engineering, and industrial machinery sectors.
