Opening Block — Where Precision Meets Personal Purpose Every ambitious project, whether it’s a sophisticated machine, a load-bearing structure, or a precision component, begins with one decisive detail — the material that will determine its strength, longevity, and ultimate character. For thousands of engineers, machinists, builders, and manufacturers across Ukraine, that decisive detail is Круглая сталь 20 — a grade of round steel that has earned unwavering trust not only for its outstanding technical characteristics, but also for the calm confidence it instills at every stage of the workflow. Here, steel ceases to be just raw metal. It transforms into a reliable foundation on which bold ideas, serious responsibility, and long-term plans can safely rest.
Who We Are Behind this product stands a close-knit team of genuine specialists who have dedicated many years to the world of industrial metallurgy. These are people who know steel the way a musician knows their instrument — its “voice” under load, its reaction to temperature changes, its behavior during machining, and the subtle nuances that separate good material from truly excellent material.
They do not simply sell metal; they accompany the client from the very first question to the moment the finished parts leave the workshop. Responsibility, crystal-clear communication, and genuine human support are not slogans for them — they are daily practice. Whether you need help choosing the optimal diameter, calculating the required length, clarifying heat-treatment recommendations, or organizing prompt delivery to any corner of Ukraine — the team is always ready to invest their knowledge and time so that you receive exactly what your project demands.
What We Offer — Product Features and Variety Круглая сталь 20 presented on our platform is a carefully curated assortment designed for the widest possible range of applications: from heavy mechanical engineering and large-scale construction to precision instrument-making and small private workshops.
The product line includes all popular diameters — from the thinnest 6 mm rods to impressive 340 mm billets — as well as any intermediate size you may require. Standard lengths of 6 and 12 meters are always in stock, but custom cutting to the exact millimeter is also available on request. Every batch is accompanied by mill certificates confirming stable chemical composition (carbon 0.17–0.24%, manganese 0.35–0.65%, and precisely controlled content of silicon, phosphorus, and sulfur), which guarantees predictable behavior during cementation, quenching, and other types of heat and chemical-heat treatment.
Strict multi-stage quality control — ultrasonic testing, surface inspection, mechanical tests for tensile strength (not less than 450 MPa) and yield strength (not less than 245 MPa) — ensures that each bar has a uniform dense structure without internal defects, accurate geometry, and excellent machinability. Whether you work on modern CNC machines or classic universal equipment, Сталь 20 forgives minor errors, cuts cleanly, and holds tolerances, saving you time, tools, and nerves.
Its balanced combination of ductility and strength makes it ideal for manufacturing shafts, axles, gears, bolts of increased strength, bushings, fasteners, and dozens of other parts that operate under medium and medium-high loads. Excellent weldability (no need for mandatory preheating in most cases), predictable hardening, and the ability to achieve surface hardness up to 60–62 HRC after cementation have long made this grade a “workhorse” in Ukrainian industry.
When It Becomes Especially Useful Experience shows that Круглая сталь 20 reveals its best qualities in the following situations: • When you need to produce a batch of parts that must combine high resilience with easy machining and minimal waste • When designing or repairing equipment that will operate under cyclic or medium static loads for many years • In construction projects where regulatory documents explicitly require materials with guaranteed mechanical properties and weldability • In factory or repair shops where predictable quality directly affects production rhythm and final product reliability • During emergency repairs and operational restocking when there is simply no time to experiment with unknown substitutes • When the customer demands full documentation package and traceability of each bar to the melting furnace
In all these cases, Grade 20 round steel acts as a universal, time-tested blank that allows you to focus on the creative and engineering part of the task rather than fighting material imperfections.
Why Customers Choose Us In a market overflowing with offers, clients return to us again and again for several simple but critically important reasons:
First — absolute honesty. The website always shows real stock availability updated in real time. What you see as “in stock” is physically in the warehouse and ready for shipment today.
Second — deep expertise. Managers are not just order-takers; they are technologists capable of advising on alternative grades, recommending optimal cutting schemes, or warning about potential pitfalls when using the material in non-standard conditions.
Third — meticulous attention to logistics and packaging. Each bundle is securely banded, protected from corrosion, and marked so that even after long-distance transportation across Ukraine the steel arrives in perfect condition.
Fourth — transparent and fair pricing without hidden markups, combined with flexible payment terms and the possibility of deferred payment for regular partners.
Fifth — complete documentation package: certificates of conformity UkrSEPRO, quality passports from leading Ukrainian and CIS metallurgical plants (Azovstal, Zaporizhstal, DMZ, etc.), and, upon request, protocols of additional tests.
All of this together creates that rare sense of confidence when you know: the material will arrive on time, will be exactly as declared, and will not let you down either in the workshop or on the construction site.
