High performance Forged 40Cr steel round bars

Product Introduction：

Carbon steel round bar is a solid cylindrical metal profile processed by hot rolling, cold drawing, forging and heat treatment. It features stable mechanical performance, high strength, good toughness, weldability and machinability. Covering precision small bars to large forged bars, it is cost-effective and widely used in construction, machinery, mold, automotive and heavy industries.

Product Advantage：

- High Structural Strength & Load Capacity: Boasts reliable tensile and compression resistance for stable structural support. S355JR high strength low alloy carbon steel round rod for heavy engineering equipment delivers outstanding rigidity and impact resistance, suitable for long-term heavy-load operation.

- High Precision & Easy Machining: Features tight tolerance and smooth finish. EN10277 C45 cold drawn bright carbon round bar precision size for machinery shaft production with accurate dimension and straightness supports various precision machining processes for shaft parts.

- Excellent Heat Treatment Performance: Allows quenching and tempering to enhance hardness and wear resistance. 45# solid carbon steel round bar quenched and tempered for automotive component machining achieves balanced toughness and stability for durable mechanical parts.

- Superior Forging & Customization Performance: Forged bars have dense internal structure and high rigidity. Large diameter forged 40Cr carbon alloy round bar for mold and mechanical fitting blanks is ideal for custom mold and mechanical blank processing.

- Good Constructability & High Cost-Effectiveness: Hot-rolled black surface bars areeasy to cut and weld. ASTM A36 hot rolled Q235B carbon steel round bar black surface for construction structure provides stable structural performance for general building projects with low cost

Product Uses：

- Building & Civil Engineering: ASTM A36 hot rolled Q235B carbon steel round bar black surface for construction structure is widely used for building frames, foundation bolts, guardrail posts, municipal steel parts and structural

reinforcement.

- Precision Machinery Shaft Manufacturing: EN10277 C45 cold drawn bright carbon round bar precision size for machinery shaft production is the ideal material for motor shafts, pump shafts, gear shafts and various precision transmission parts.

- Heavy Engineering Equipment: S355JR high strength low alloy carbon steel round rod for heavy engineering equipment is widely used for crane components, mining machinery parts, engineering vehicle and large load-bearing equipment structures.

- Mold & Mechanical Blank Processing: Large diameter forged 40Cr carbon alloy round bar for mold and mechanical fitting blanks applies to mold blanks, fixture blanks, heavy gears and high-rigidity thick mechanical parts.

- Automotive Component Machining: 45# solid carbon steel round bar quenched and tempered for automotive component machining is commonly processed into automotive suspension parts, engine accessories, transmission shafts and chassis structural parts.
