SA-240 Type 304 Sheet Gangsteel Stainless Solution

SA-240 Type 304 Sheet: Gangsteel Stainless Solution in China

Introduction to SA-240 Type 304 Sheet

SA-240 Type 304 sheet is a thin-gauge austenitic stainless steel product under the ASME SA-240 specification for chromium-nickel stainless steel sheet, plate, and strip, designed for pressure vessels and general fabrication. This grade, with its 18% chromium and 8% nickel makeup, delivers strong corrosion resistance, easy formability, and non-magnetic properties, making it perfect for applications needing lightweight yet durable materials. Sheets typically range from 0.3 mm to 6 mm thick, ideal for bending, stamping, and welding into components like enclosures and linings.

Gangsteel, China's innovative stainless steel manufacturer and exporter, produces SA-240 Type 304 sheets with precision rolling for uniform thickness. As experts in ASME SA240 stainless steel plates, Gangsteel supplies custom-cut sheets with rapid turnaround for worldwide clients. This article breaks down SA-240 Type 304 sheet's specs, benefits, and uses for 2025 engineering needs.

What is SA-240 Type 304 Sheet?

SA-240 Type 304 sheet is a flat-rolled austenitic stainless steel with a stable microstructure that resists magnetization, offering high ductility for intricate shaping. Annealed at 1010-1120°C and quenched, it achieves a smooth surface for finishes like 2B or BA, enhancing aesthetics in visible applications. Equivalents include UNS S30400, EN 1.4301, and JIS SUS304, allowing cross-standard use. Gangsteel's SA240 Gr 304 sheets undergo cold-rolling for tolerances ±0.05 mm, per ASTM A240 stainless plate guidelines, suiting precision tasks like laser cutting for electronics housings.

Chemical Composition of SA-240 Type 304 Sheet

The composition of SA-240 Type 304 is calibrated for corrosion protection and formability, with maxima per ASME SA-240:

Gangsteel's AOD refining yields low S/P for sheets with PREN ~19, resisting urban pollution per ASTM G50.
