GB/T 20878 AISI 304 Stainless Steel Coil – Product Overview

The GB/T 20878 AISI 304 Stainless Steel Coil is one of the most widely used stainless steel grades in the world, known for its excellent combination of corrosion resistance, formability, and high tensile strength. AISI 304 is an austenitic stainless steel, often referred to as 18/8 stainless steel due to its composition of approximately 18% chromium and 8% nickel. This alloy provides outstanding resistance to oxidation, corrosion, and a variety of chemicals, making it ideal for a wide range of applications, including in the food processing, medical, architectural, and chemical industries. Yuanchi Metal provides high-quality GB/T 20878 AISI 304 Stainless Steel Coils, available in various thicknesses, widths, and finishes, to meet the specific demands of our customers.
