High tensile strength ensures that tools made from H13 steel can maintain their shape and functionality over prolonged use, even under strenuous conditions.
Moderate Corrosion Resistance: While H13 is not as resistant to corrosion as some other steels (like austenitic stainless steels), it does offer moderate corrosion resistance due to its chromium content. This level of resistance is generally sufficient for many tooling and industrial applications, particularly where the primary concerns are strength and toughness rather than extended exposure to corrosive environments.
Resistant to Thermal Fatigue Cracking: One of the notable features of H13 steel is its resistance to thermal fatigue cracking. This property makes it particularly suitable for applications involving cyclic heating and cooling, which is a common scenario in injection molding and other tooling processes. Thermal fatigue cracking occurs when materials are repeatedly heated and cooled, causing expansion and contraction that can lead to cracks and failure over time. H13's resistance to this phenomenon ensures a longer service life for tools and components made from this steel, even in environments with significant thermal cycling.
