Steel Round Bar/Steel Bar, Q235B, Q355B, 10#, 20#, 35#, 45#, 20Cr, 40Cr, 20CrMo, 42CrMo,
Round Steel is a kind of long solid steel product with circular cross-section. As a basic industrial profile, it is widely used in machinery manufacturing, hardware processing, fastener production, automobile parts, mold making, steel structure, construction engineering, petrochemical industry, general equipment manufacturing and other fields.
According to production process, it can be divided into Hot Rolled Round Steel, Cold Drawn Round Steel and Forged Round Steel. According to material grade, it includes Carbon Structural Steel, High Quality Carbon Steel, Alloy Structural Steel, Stainless Steel, etc. Common materials are Q235B, Q355B, 10#, 20#, 35#, 45#, 20Cr, 40Cr, 20CrMo, 42CrMo, etc., which can meet different requirements of strength, toughness, wear resistance and processing performance.
The products comply with Chinese standard, American standard, European standard and other international standards. The specifications are complete, with diameter ranging from 8mm to 300mm. The length can be produced as fixed length, multiple length or non-standard size according to customer requirements.
Hot Rolled Round Steel features high efficiency and cost performance, widely used for structural parts, mechanical blanks, construction and general processing. Cold Drawn Round Steel has high dimensional accuracy, smooth surface and good straightness, suitable for precision parts, shafts, pins, bolts and other components with strict requirements on size and appearance. Forged Round Steel has compact internal structure and excellent mechanical properties, often used for high-strength and high-load key components.
Round Steel has good machinability, weldability and heat treatment performance, with stable mechanical properties and strong bearing capacity. It can be processed by turning, milling, drilling, grinding, quenching and tempering, etc.
All products undergo strict dimensional inspection, mechanical property test and surface quality inspection before delivery to ensure stable and reliable quality. We can provide customized packaging, transportation, commodity inspection and customs declaration services according to customer orders, which are widely used in domestic and foreign engineering construction, machinery manufacturing and export trade.
