Round stainless steel 40X13 isn’t just metal — it’s the quiet promise that the things you make today will still be here, unchanged, for the people you care about tomorrow.
Who We Are
Ukrpostachservis has been supplying technical stainless steel across Ukraine for over 15 years. The team consists of engineers and technologists who once stood at machines themselves, so every diameter, every grade, every certificate is checked the way they would check it for their own workshop. We don’t sell “approximately” — we supply exactly what will work without surprises.
What We Offer
Round bar 40X13 (AISI 420 modified) is a martensitic stainless steel that combines high hardness after heat treatment with good corrosion resistance. Available diameters: from 5 mm to 300 mm. Delivery forms: hot-rolled, forged, calibrated (h9–h11), polished. Each batch comes with a factory certificate and our own incoming control report. We cut to size from 10 cm to 6 m without extra charges — you pay only for the weight you actually need. Key properties that matter in real work: Hardens up to 50–55 HRC Holds an edge longer than 12X18H10T Resists atmospheric corrosion and weak acids Remains magnetically detectable (important for many devices) This is the steel chosen when the part must be both sharp and durable.
When 40X13 Becomes the Right Choice
Medical instruments and dental tools that are sterilized daily Blades and cutting elements for food lines Shafts, axles and fasteners in humid or mildly aggressive environments Molds and dies that require wear resistance and polishability Custom knives and tools where the owner values honest steel without marketing myths Repair of vintage equipment, when original spare parts have long been out of production
Why Customers Stay With Us for Years
Orders are shipped the next day after payment — from stock in Dnipro. No minimum lot: you can buy one bar or a wagon. Honest weight — scales are checked by the state metrology service every quarter. We remember regular customers and their typical sizes; the second and next orders are processed faster. If something doesn’t fit, we replace it ourselves, without endless correspondence. The phrase that customers most often write to us after receiving the metal: “Finally, the steel is exactly as it should be.”
