304L 316L 321 stainless steel sheets with competitive pricing

304L Stainless Steel Plate
As a low-carbon austenitic stainless steel (carbon ≤ 0.03%), 304L is resistant to intergranular corrosion after welding and is widely used in food processing, chemical equipment, and architectural decoration. It contains 18% chromium and 8%-12% nickel, making it resistant to nitric and phosphoric acid corrosion, but less resistant to chlorides. Its cost is lower than 316L.

316L Stainless Steel Plate
The addition of 2%-3% molybdenum significantly improves corrosion resistance, making it particularly suitable for seawater and highly corrosive chemical environments (such as dye and fertilizer equipment). It offers high high-temperature creep strength and excellent work hardening properties, but its price is approximately 30% higher than 304L.

321 Stainless Steel Plate
By adding titanium (Ti ≥ 5×C%) to stabilize carbides, 321 steel offers outstanding resistance to intergranular corrosion at high temperatures (425-860℃) and is widely used in high-temperature components such as aviation and boilers. Its mechanical properties are close to those of 304 stainless steel, but attention should be paid to the effect of titanium on the toughness of the heat-affected zone during welding.
