ما هو فولاذ مستدير?
This type of steel features a solid circular cross-section and is typically supplied in straight lengths. It is valued for its balanced strength, durability, and versatility across structural and mechanical uses.
Definition of Round Steel
Circular steel products are produced through hot rolling or cold drawing, depending on application needs. Compared with other shapes, this form offers uniform load distribution and reliable machinability.
Common Materials Used
- Carbon steel for general-purpose use
- Alloy steel for higher strength and wear resistance
- Stainless steel for corrosion-prone environments
عملية التصنيع
As a direct factory supplier, we maintain strict production control to ensure stable quality and consistency.
Hot Rolled Production
Hot rolling is performed at elevated temperatures, allowing efficient forming and cost-effective output. This method is commonly used for construction and heavy-duty components.
Cold Drawn Production
Cold drawing improves dimensional accuracy and surface finish. It is well suited for precision parts, shafts, and machining applications.
ضبط الجودة
Each batch undergoes chemical analysis, mechanical testing, and dimensional inspection to meet international standards.
Grades and Material Standards
Material selection plays a critical role in performance, safety, and service life.
Carbon Steel Grades
Carbon-based materials are widely used due to their strength-to-cost ratio and broad application range.
Alloy Steel Grades
Alloyed materials enhance mechanical performance, making them suitable for demanding industrial environments.
International Compliance
Products are manufactured according to ASTM, EN, DIN, and JIS specifications, ensuring global compatibility.
Sizes, Diameters, and Tolerances
