Stainless Steel Sheets and Plates
Riddhi Metal Corporation metals offer 300 Series stainless steels sheets and plates(309,310,321,317L) which are austenitic, and are hardenable just by cold working techniques in the form of 2B/2D Finish , Polished Sheet, Perforated Sheet, Flat & Expanded Plate Mill Plate, Diamond Plate . These evaluations of stainless have chromium (approx. 18 to 30%) and nickel (approx. 6 to 20%) as their major alloying increases. 300 Series Stainless steel alloys resist corrosion, keep up their quality at high temperatures and are anything but difficult to keep up.
It has various advantages such as:- Heat exchangers
- Shipbuilding
- Pulp and paper
- Marine construction
- Pipe systems in chemical tankers
- Blast walls on the offshore platforms
- better corrosion resistant properties
- developed for applications requiring extensive machining operations
- non-magnetic properties
- scratch resistant
- many Finishing options: polishing, beveling, etc
We also have 400 series group of stainless steels sheets and plates (410,420)which has 11 percent chromium and 1-percent manganese increment, over the 300 arrangement aggregatein forms of Plate Mill Plate, Coil Plate,2B/2D Finish, Polished Sheet, Perforated Sheet, Flat & Expanded. The 400 arrangement is helpless to rust and corrosion under a few conditions. Heat treating will solidify the 400 series. The 400 arrangement of stainless steels have higher carbon content, giving it a martensitic crystalline structure. This gives high quality and high wear resistance. Martensitic stainless steels aren't as erosion safe as the austenitic sorts.Ferritic or nonhardenable stainless steels, Martensitic or hardenable stainless steelsare classified in the 400 series.
