A4 grade of Stainless Steel is the same as A2 grade. Stainless Steel A4 contains 16% chromium, 10% nickel and 2% molybdenum. Additional Molybdenum increases the corrosion resistance in Stainless Steel which endure attack from many industrial chemicals and solvents. Stainless Steel A4 is austenitic, nonmagnetic material which is suitable for all the situations as A2. But Stainless Steel A4 is also ideal for marine solutions. This Stainless Steel A4 is perfect for Fastener manufacturing, and it is easier to fabricate, weld, and finish. Use of Stainless Steel A4 grade is the most convenient and absolute choice. This material is also suitable in applications in surgical implants, photographic chemicals, and the marine environment.
