Aiman Metals stands out as a top-notch manufacturer and supplier of premium tool and die steels, including H13 bars, right from Kuala Lumpur, Malaysia. Known for their unwavering dedication to quality and precision, Aiman Metals delivers H13 steel bars that adhere to strict industrial standards, making them perfect for the demanding needs of tooling and die-making. With a solid foothold in both the Malaysian and Southeast Asian markets, they serve a variety of industries such as automotive, aerospace, and plastic molding. By blending advanced processing methods with timely delivery and outstanding customer service, Aiman Metals provides reliable H13 tool steel solutions tailored to meet client specifications and performance needs.
When it comes to the composition and mechanical properties of H13 tool steel bars, they typically contain Chromium (4.75–5.50%), Molybdenum (1.10–1.75%), Vanadium (0.80–1.20%), Carbon (0.32–0.45%), along with trace amounts of Silicon, Manganese, and Iron. This steel boasts impressive toughness, remarkable thermal fatigue resistance, and solid hot hardness. After heat treatment, H13 achieves a hardness of about 44–52 HRC and can endure repeated heating and cooling cycles without cracking. With a tensile strength of around 1,500 MPa, H13 is perfect for applications that demand high strength, wear resistance, and thermal stability in extreme conditions.

H13 tool steel bars find extensive use in hot work applications thanks to their outstanding heat resistance and durability. They are commonly employed in the production of extrusion dies, die-casting molds, hot shear blades, and forging dies. In the plastic molding sector, H13 is particularly popular for molds that require a high polish and dimensional stability. Its performance in high-temperature settings makes it an excellent choice for tooling subjected to thermal cycling. Additionally, H13’s ability to resist abrasion and cracking under stress makes it ideal for precision tools in the aerospace industry.
