What do you mean by a Plate?
Plates are categorized as metals and alloys that come in the form of metal plate or flat plates stock. The plates are having a minimum thickness of 0.25 inch, although they can be thicker than ¼ inch. Metal plates are commonly made from stainless steel, titanium and vitallium among other materials.
What is Grade 409M?
Stainless Steel grade 409M is a new version of Stainless Steel 409 with lower carbon content of 0.03%. It is used to replace carbon steels and low alloy steels in applications requiring higher strength, weldability, abrasion resistance and slide-ability. It has good scaling and oxidation resistance at high temperatures, including sulfur-containing atmospheres.
SS Grade 409M is used in bulk solids handling areas/bunkers, petrochemical, shipping-waggons, mining & quarrying, sugar, irrigation, forestry, sewage treatment plants, and general engineering industries.
The Grade 409M Plates has high tensile strength, and it has excellent resistance to atmospheric corrosion and exhaust gas. SS 409M superior to 410 martensitic grades containing 12% chromium. Furthermore, it has temperature tolerance up to 675 ° Celsius. These plates can also be used at high and elevated temperatures, providing improved results while remaining undamaged.
SS 409M Plate is a ferritic steel that is generally referred to as a chromium stainless steel because of its excellent corrosion resistance. Some chemical elements, such as carbon, silicon, and manganese, contribute to the steel’s critical properties. Strong mechanical efficiency, excellent resilience, hardness, and weldability in a high-temperature setting are among the properties given.
Type 409M stainless steel has a special chemical composition that contains
- Carbon-10.5 to 11.75 %
- Iron-0.08 min
- Nickel- 0.5 min
- Manganese-1 max
- Silicon-1 max
- Phosphorus- 0.045 max
- Sulfur-0.3 min
- Titanium- 0.075 max
