Circles

Stainless Steel Circle is a type of the stainless steel sheets and plates that come in the form of a circle.The Stainless Steel Circle comes in different grades of material such as 304, 304L, 316, 316L, 310, 317L and 321 grades.The thickness of the circles range from 1mm to 100mm and the SS 304 Blanks are the most used in the industries. The 304 material is cost effective for general corrosive applications. For applications that require extra corrosion resistance, especially for chloride ion stress corrosion cracking resistance, the Stainless Steel 316 Blanks are used. The 316 material has 201MPa minimum yield strength, 515MPa minimum tensile strength, 870 degrees operating temperature and good hardness. There also other types of blanks.
