AISI H13 ESR hot work mold steel plate is an electro-slag remelted chromium-based tool steel designed to meet the most rigorous thermal engineering standards. KUTU’s premium AISI H13 ESR hot work mold steel plate features extreme micro-structural cleanliness and unparalleled isotropic properties. This makes it the premier choice for manufacturing heavy-duty aluminum die casting molds, hot extrusion dies, and high-pressure forming tools operating under extreme temperature cycles.
The advanced ESR refining process eliminates gas porosity and carbide segregation, giving our AISI H13 ESR hot work mold steel plate extraordinary resistance to thermal fatigue and heat checking. When subjecting tools to constant cooling and heating forces up to 600°C, KUTU’s material ensures complete dimensional safety and flawless surface quality on cast alloy components, boosting long-term production efficiencies.
A：Absolutely. Beyond supplying raw materials, we provide full custom precision machining services. This includes CNC milling, grinding, surface flattening, and custom vacuum heat treatment tailored to your exact blueprints. We deliver near-net-shape blocks to save your production time.
A：Yes, our facility is equipped with heavy-duty CNC milling machines, high-precision grinding machines, and automated sawing systems. We supply not only raw tool steel plates but also fully machined mold bases and custom-sized steel blocks according to your industrial specifications.
A: Our comprehensive service covers everything from steel grade selection consulting to custom cutting, precision machining, and full internal ultrasonic testing (SEP 1921-84). This ensures global toolmakers receive ready-to-use materials with guaranteed quality.
A： Yes, absolutely. We understand that tool and mold steel reliability is critical to your tooling life and production stability. We provide free material samples (standard test blocks or small discs) for metallurgical analysis, chemical composition testing, and hardness verification. You can place a sample request via our chat or contact forms.
A： While the steel material itself is 100% free, international express freight (via DHL, FedEx, or UPS) is typically covered by the buyer. You can provide your courier account number for freight collect. Our Premium Policy: The exact shipping cost you paid for the sample will be 100% credited back and deducted from your first bulk trial order invoice, making the entire sample process completely risk-free for you.
