| The steel core provides high strength and formability, and the zinc coating is unmatched as an effective and economical protection. |
| The manufacturing process generally requires materials with good cold formability. |
| Grade A material will provide the greatest cold formability with grades B, C and D providing progressively less formability in that order. |
| Plain tubes for feeders or connectors have to comply with stringent requirements with regard to formability and coupling technology. |
| The alpha-beta alloys are widely used because of their good combinations of strength, toughness, and formability. |
| Another grade of 430 with niobium added for improved formability and surface characteristics. |
