Product Q&A
Q:What is the difference between forging and casting?
A:
Forging transforms solid metal from one shape to another through plastic forming (hot or cold), while casting transforms liquid metal into a solid shape by pouring it into a mold. Forging improves mechanical properties, whereas casting focuses on melting and pouring processes.
Q:How to choose high-quality forgings?
A:
Select forgings by checking external appearance for defects like cracks or wrinkles, and internal quality through chemical composition analysis, mechanical property tests (tensile strength, hardness), and microscopic structure inspection using specialized instruments.
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. Both methods ensure structural integrity for circular and ring forgings.
Q:What customization options are available for this steel bar?
A:
We offer flexible customization including full customization, minor customization, and customization from designs or samples. Shapes can be round, square, shaft, ring, or cylinder, with customized sizes.
Q:What certifications does the product hold?
A:
The product is certified under GB/T19001-2016 and ISO9001:2015 standards, ensuring compliance with international quality management systems.
