409/409M/409L Plates & Coils
Stainless steel Sheet Plates & Coils 409/409M/409L, 304, 304L, 309, 310, 316, 316L, 316TI, 317,
317L, 321/321H, 904L
409/409M/409L Sheets & Plates are having the properties of highly corrosion resistance. The layer produces of chromium oxide helps them to be corrosion and stain-resistant. SS Plates & steel if compare with other metals it has the highest strength to weight ratio. This type of Stainless steel is easy to clean so it helps in maintaining the cleanliness also. It is hundred percent recyclable also.
409/409M/409L Sheets & Plates are applied mainly in the automotive exhaust industry but it is highly used in some other applications also like mufflers, catalytic converter, tailpipes, in hospital, Heat exchanger tubing, furnace component, etc. Various tests are duly performed for assuring the quality. The test performs are radiography test, flaring test, third-party inspection, PMI test, flattening test. After the entire test, the SS 409 Sheets & Plates are packed in wrappers or bundles to avoid delivery damages.
