430-grade stainless steel is usually used in any application where aesthetic appearance is more concerned than strength. It has a tensile strength of 65ksi (minimum) and 30ksi for yield strength (minimum). 430 belongs to the ferritic grade family and is considered one of the best options for cost-conscious buyers.
Extensive Configuration of 430 Stainless Steel
The 430-grade stainless steel can be classified into different formats such as:
- Stainless Steel Sheet
- Stainless Steel Tube (round tube, square tube, oval tube, rectangular tube)
- Stainless Steel Foil
- Stainless Steel Plate
- Stainless Steel Strips
- Stainless Steel Round Bar (plain or corrugated)
- Stainless Steel Angle Bar
- Stainless Steel Hexagonal Bar
