AISI D2 SKD11 DC53 cold work tool steel round bar is a high-carbon, high-chromium alloy engineered to meet the absolute highest standards of wear resistance and edge retention. KUTU offers top-grade AISI D2 SKD11 DC53 cold work tool steel round bar from 4mm to 200mm in diameter, tailored explicitly for severe cold stamping molds, heavy-duty punching dies, industrial shear blades, and thread rolling setups.
This multi-grade tool steel series features a dense concentration of hard chromium carbides within its refined microstructure, providing premium protection against abrasive mechanical friction. KUTU’s specialized vacuum degassing processes ensure deep hardening penetration and excellent dimensional stability during heat treatment, helping international punch-and-die factories maximize structural tool lifespan and prevent edge chipping under heavy high-stress automated production cycles.
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.
