Stainless Steel 304 Sheets, SUS 304H Plate, SS UNS S30400 Plates, 304H Stainless Steel Hot Rolled Plates, ASTM A240 SS 304 Sheets, Stainless Steel 304L Cold Rolled Sheets, SS Werkstoff No 1.4301 Sheets, SS 304 Perforated Plates Dealer in India.
Kalpataru Piping Solutions is a leading exporter of 304 stainless steel sheets, known for their ability to withstand heavy loads and pressure. These sheets can be customized according to client specifications. Stainless Steel UNS S30400 Plates are a popular choice due to their chromium and nickel content, giving them non-magnetic properties. SS 304H Perforated Plates are highly valued in the automotive and aerospace industries where high stress resistance is crucial.
These plates perform well at elevated temperatures, particularly between 649°C and 760°C (1200°F–1400°F), making them suitable for advanced reactor designs. ASTM A240 SS 304 Sheets offer good workability, though they are slightly less machinable than free-machining stainless steel. Soldering SS 304L Cold Rolled Plates can be challenging due to potential cracking and segregation in the microstructure. Stainless Steel 316 Plates are designed for gas–tungsten–arc and gas–metal arc welding processes. The high molybdenum content in SS UNS S30409 Plates enhances their resistance to pitting and crevice corrosion. The presence of niobium stabilizes the alloy during welding, preventing intergranular cracks. Alloy 304H plates offer excellent machinability in treated conditions, and their microstructure is similar to that of carbon and low-alloy steels.

FAQ
What is the difference between 304L and 304H?
304L has a lower carbon content, reducing the risk of carbide precipitation at high temperatures. 304H, with higher carbon content, offers significantly greater strength at elevated temperatures, making it the preferred choice for applications requiring both high-temperature resistance and corrosion resistance.
What is stainless steel grade 304 and 304L?
Stainless steel grades 304 and 304L both contain a minimum of 18% chromium and 8% nickel. The key difference between them is the carbon content: Grade 304 has a maximum carbon content of 0.07%, while Grade 304L has a lower maximum carbon content of 0.030%.
What is 304H stainless steel?
304H stainless steel, also known as Alloy 304/304H (UNS S30400/S30409), is a high-carbon modification of the widely used “18-8” chromium-nickel austenitic stainless steel. The carbon content in 304H is controlled between 0.04% and 0.10%, providing increased strength at elevated temperatures above 800°F (427°C).
