Часто задаваемые вопросы
What is GB/T3190-2020 Standard?
GB/T 3190-2008 is China’s national standard that defines chemical composition for wrought aluminum alloys, equivalent to EN 573-3 and ASTM aluminum grade specifications.
What is the difference between GB aluminum grades and ASTM/AA grades?
Chemical compositions are almost identical for most alloys. Only a few grades (such as 2A50 or Q345B) are China-specific. For all others, we provide direct equivalents to help you compare easily.
Can you provide mechanical properties for custom-forged parts?
Yes. We can supply tensile strength, yield strength, elongation, and hardness values according to the required heat treatment and forging condition (e.g., T6, T73, normalizing, quenching).
Are stainless steels like 304 and 316L suitable for forging?
Yes, but they behave differently from aluminum and carbon steel. Stainless steel requires higher forging temperatures and more controlled processing. We can forge 304 and 316L depending on your design.
Can you provide samples or small-batch runs for material testing?
Yes. We support prototyping and small trial runs before mass production, especially for new projects or performance validation.
Do you offer heat treatment for these materials?
Yes. We provide T6/T73 for aluminum and quenching/tempering/normalizing for alloy steels such as 35CrMo and 42CrMo.
