Product Q&A
Q:What is the difference between forging and casting?
A:
Forging transforms solid metal into another shape through plastic deformation, while casting involves pouring molten metal into a mold to solidify. Forging improves mechanical properties by refining grain structure, whereas casting is suitable for complex shapes but may have lower strength.
Q:How to choose high-quality forgings?
A:
Select forgings by checking external dimensions, surface defects (cracks, wrinkles), and internal properties via chemical composition analysis, macroscopic/microscopic structure inspection, and mechanical tests like tensile strength and hardness.
Q:What are the characteristics of the forging process for blank forgings?
A:
The process includes pier roughening, elongation, punching, and expanding. Free forging uses a horse screw for hole expansion, while ring rolling uses rolling mills, offering different efficiency and precision levels.
Q:What materials are used for these crankshafts?
A:
The crankshafts are made from 45# carbon structural steel (equivalent to S45C, 1045, or SM45), known for good cutting performance, high hardness after quenching, and excellent strength and toughness.
Q:What is the minimum order quantity (MOQ)?
A:
The minimum order quantity is 1 piece, allowing for flexible purchasing for various project sizes.
