A4-70 indicates a stainless property class commonly associated with a minimum tensile strength level of 700 MPa under ISO 3506 reference conditions.<\/p>\n        <p>For many buyers, the most important comparison is A2 versus A4. A2 is suitable for general indoor and mild outdoor applications, while A4 is typically preferred for marine air, chemical equipment, wastewater facilities, and coastal structures.
