Why choose us? - 304 vs 430 Stainless Steel: 304 is the most common commercial-grade alloy, it contains around 18% chromium and 8% nickel. 430 Stainless steel is less expensive because it does not contain nickel. 430 is magnetic while 304 is not. 430 is more difficult to form and weld than 304. - 430 stainless steel does not corrode, pitting, rust or wear. Because 430 stainless steel has excellent corrosion resistance, it allows structural components to permanently maintain the integrity of their engineering design. Chromium-containing stainless steel also combines mechanical strength and high elongation, making it easy to fabricate components to meet the needs of architects and structural designers. - The double-sided films can protect it from being scratched. - Easy to drill and cut to desired size, but please be safe when operation, keep it from tearing and cutting your fingers. - 430 Stainless Steel is widely used in construction, electronics, transportation, shipping, auto repair, DIY projects, hobbies, crafts, architectural decoration, industry and various other projects from art, or hobby work to industrial and scientific use.
