SS 304L CR 240 Grid 1sf

Metals

RVS 304L KGW K240 1ZF is a cold-rolled, austenitic chromium-nickel stainless steel sheet with a ground surface (grain 240) and one-sided protective film. Thanks to its low carbon content (L = low carbon), this material is highly weldable without risk of intergranular corrosion. The combination of good corrosion resistance, attractive finish, and workability makes it ideal for visual applications in demanding environments.
Known alternative designations include 1.4307, AISI 304L, and X2CrNi18-9.

Frequently Asked Questions about SS 304L CR 240 Grid 1sf

What does “KGW K240 1ZF” mean?

“KGW” stands for cold-rolled, “K240” refers to the 240-grit finish achieved by polishing, and “1ZF” indicates a protective film on one side.

Is 304L stainless steel suitable for food-industry use?

Yes, 304L meets all food-contact standards and is widely used in food processing.

Can 304L KGW K240 1ZF be welded?

Yes, its low carbon content ensures excellent weldability without risking intergranular corrosion.

What is the difference between 304 and 304L stainless steel?

304L has lower carbon content than 304, making it better for welding applications where intergranular corrosion must be avoided.

Is this material suitable for marine environments?

No, for chloride-rich or marine conditions, 316L is recommended due to its superior corrosion resistance.

What thicknesses are standard?

304L KGW K240 1ZF is typically available in 1 mm to 4 mm, depending on the supplier.

Can it be used for visible architectural work?

Yes, the smooth K240 surface and protective film make it perfect for decorative and exposed installations.

Is the material magnetic?

304L is austenitic and essentially non-magnetic, although slight magnetism can develop after heavy cold forming.
