Gayatri Tubes take pride in being one of the leading suppliers of SS 304 / 304 L / 304 H Sheet Plate / Structurals. We serve a large group of clients with our quality products. We offer sheets in various sizes and dimensions. These sheets comprise of considerable content of chromium and nickel in it. Stainless Steel 304, 304L, 304H Sheet Plate / Structurals have lower amount of carbon content in it. It is commonly used in making cooking pans and other cooking tools. These alloys are the most versatile and widely used in this family of alloys. These sheets exhibit tremendous resistance to corrosion. Hence, fabrication and formability applications become easier with these sheets. These are very easy to weld.
It offers stable resistance to oxidizing environments. And this happens due to the availability of chromium in it. Due to the nickel content in the sheets, these offer high level resistance to aggressive organic acids. Metal sheets from 304 L have lower corrosion rates as compared to sheets with 304. When the environment is prone to intergranular corrosion than metal sheets with 304 L are preferred. Austenitic Stainless Steel 304/304L/304H Sheet Plate / Structurals are extremely resistant to carbide precipitation. In an application, one can easily heat these sheets in high-temperature ranges. With this variety of sheets post welding annealing is not necessary. To go with that these offer excellent welding characteristics. It is easy to hot form but you have to maintain temperature from 2100 degrees to 2300 degrees F. The use of chip breakers is advisable to carry out relevant applications successfully.
These sheets are common in use in a wide variety of home and commercial applications. Some of these applications are in food processing equipment, beer brewing, and milk processing and winemaking in particular. To go with that kitchen bench, equipment sinks, and appliances also make good use of these sheets. Even architectural trim and molding use sheets of this alloy. It is commonly used in automotive and aerospace structural use and as a construction material in large buildings. Many industries make use of these sheets in heat exchangers and in chemical containers. The dyeing industry is one of the most prominent users of these sheets.
