The Material That Turns Precision into Everyday Reality
When a toolmakers, die makers, or plant engineers select steel for a critical component, the decision is never random. It is forged from years of trial and error, from blades that held an edge for thousands of cycles and from dies that cracked on the 987th stroke. In this world, high-carbon tool steel 9XC (9HS, GOST 5950-2000, close analog to DIN 100MnCrW4 and AISI O1) has earned its permanent place on the shortlist of materials that simply do not let professionals down.
Sheets and strips of 9XC steel in thicknesses from 8 mm to 60 mm are far more than raw metal. They are the foundation upon which accuracy, repeatability, and long-term profitability are built. For anyone who works to tolerances measured in hundredths or thousandths of a millimeter, this grade is not just “another tool steel” — it is a trusted partner that behaves exactly the same way batch after batch, year after year.
Who We Are
Behind every delivered ton stands a team that once stood at the machines themselves. We know what it feels like when a punch breaks in the middle of a night shift, when a €40,000 die fails because the steel had hidden decarburization, or when an entire batch of knives loses hardness after the first regrind.
That is why we treat 9XC the way surgeons treat instruments — with absolute respect. Every sheet and every strip undergoes incoming inspection: chemical composition verification, hardness testing in the annealed state, and, when required, ultrasonic flaw detection. We deliberately cut out all fly-by-night middlemen and work directly with two of Ukraine’s most respected metallurgical plants that still produce 9XC the old-school way — open-hearth or electric-arc furnace, careful deoxidation, and strict control at every heat.
This allows us to look every customer in the eye and say with confidence: “The material you receive today will be identical to the one you bought last year and the one you will buy in 2028.”
What We Offer — Properties That Matter in the Real World
9XC steel contains 0.85–0.95 % carbon, 0.95–1.25 % chromium, 0.40–0.70 % manganese, 0.95–1.25 % silicon, and up to 0.15 % vanadium in selected heats. After proper heat treatment (oil quenching from 800–840 °C followed by low-temperature tempering at 160–220 °C), it reliably achieves 60–63 HRC while retaining enough toughness to withstand moderate impact loads — a balance that faster-cutting modern PM steels often struggle to match in thick sections.
Our stock program is built around the sizes professionals actually use:
- Hot-rolled and cold-rolled sheets 8 to 60 mm thick
- Strips 40–500 mm wide in the same thickness range
- Precision guillotine and band-saw cutting to customer dimensions with ±0.5 mm tolerance
- Optional pre-hardening and tempering service for ready-to-finish blanks
All material is supplied in the soft-annealed condition (207–229 HB) for easy machining, but we can also deliver quenched-and-tempered parts machined to your drawing if required.
When 9XC Becomes Truly Indispensable
This steel shines brightest in applications where wear resistance directly translates into money saved:
- Medium- and high-volume cutting tools (guillotine blades, rebar shears, rotary slitters, granulator knives)
- Cold and semi-hot forming dies, drawing punches, bending tools, and trimming dies
- Precision measuring instruments (plug gauges, ring gauges, snap gauges, master plates) that must remain dimensionally stable for decades
- Crushing and grinding equipment components (hammers, breaker bars, liner plates) exposed to severe abrasion
- Cost-effective repair and replacement of worn European or American machine parts when original spare parts are either unavailable or astronomically expensive
In each of these cases, the superior edge retention and abrasive-wear resistance of 9XC reduce downtime, extend maintenance intervals, and keep part geometry consistent over thousands of production cycles.
Why Serious Professionals Keep Coming Back to Us
- Zero surprises. Every heat comes with the original mill certificate plus our own independent test report.
- Real stock, real speed. 98 % of standard thicknesses 8–60 mm are physically on the floor and ready for same-day or next-day shipment.
- Honest cutting. We do not “approximate” — we deliver the exact length and width you ordered on modern equipment.
- Proper storage. Climate-controlled warehouse, no rust, no dings, or moisture damage — the steel arrives in the same condition it left the mill.
- Real technical support from engineers who have personally heat-treated hundreds of tons of 9XC and can tell you exactly how to avoid quench cracks in a 50 mm plate or why you should temper at 180 °C instead of 200 °C for your particular application.
- Flexibility without bureaucracy. Need 47 mm thickness because your old die was made from an odd size decades ago? We will roll or forge it for you. Need just 300 kg for an urgent repair? No problem — we won’t force you to buy a full ton.
