304 stainless steel is a general-purpose grade containing at least 18% chromium and 8% nickel, offering excellent corrosion resistance and formability. The L variants (304L, 316L) have lower carbon content to reduce intergranular corrosion susceptibility.

Packaging & Shipping

Available in small packing, carton packing, or pallet configurations. All products undergo quality inspection before shipment from Shenzhen port.
