The presence of chromium creates an invisible surface film that resists oxidation and makes the material “passive” or corrosion resistant. The SUS445 stainless steel contains small. The elongation is smaller by a factor of 10. Due to the addition of Molybdenum (Mo), SS 316 has a great improvement in corrosion resistance and certain properties compared to SS304. For instance, 304 stainless steel forms a radius 20 to 22 percent of the die width, while a radius in 5052-H32 aluminum forms at 13 to 15 percent of the width. Therefore, the potential energy is smaller by a factor of 10. SOLIDWORKS defaults to calculating the flat pattern using the K-Factor. The bending tool has a radius of 30 mm which means that our Inside Bend Radius (R) is 30 mm.
