FAQs
Start with application and processing method. Shape and form determine feasibility before grade selection.
Only in medium-to-large volumes. For small quantities, cut sheets may be more economical.
They follow different standards and tolerances. Choosing incorrectly may cause compliance issues.
When fatigue resistance, load reliability, or safety-critical performance is required.
Not necessarily. They often reduce machining, labor, and project lead time.
Yes. Many finishes improve corrosion resistance, hygiene, and wear behavior.
Choosing grade first and product form later — this often leads to redesign and higher cost.
