EN 1.4301, ASTM TYPE 304 / UNS S30400 Welded Precision Stainless Steel Tubing 12 X 1.5MM EN10217-7 W2R
Description:
304/4301 Welded Precision Stainless Steel Tubing is a classic 18% chromium, 8% nickel austenitic stainless steel. It’s an all-purpose product with good corrosion resistance and is suitable for a wide variety of applications that require good formability and weldability. 304/4301 can be delivered with a variety of surface finishes.
304/4301 is an austenitic stainless steel, which belongs to the standard CrNi stainless steel family. 304/4301 is the basic variant with normal carbon and nickel content.
The austenitic CrNi standard grades are the most widely used group of stainless steels. Their well-balanced material properties make them suitable for the fabrication of many products.
304/4301 is commonly available from many stainless steel stockists in many product forms and dimensions. It can be supplied with a wide range of functional and aesthetic surface finishes.
