Product Description
AISI 304 JIS SUS304 DIN 1.4301 Stainless Steel Round Bar
1: 304 Steel Introduction
SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel and is essentially non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.
It is specified by SAE International as part of its SAE steel grades. Outside the US it is commonly known as A2 stainless steel, in accordance with ISO 3506 for fasteners.[3] In the commercial cookware industry it is known as 18/8 stainless steel. In the unified numbering system it is UNS S30400. The Japanese equivalent grade of this material is SUS304. It is also specified in European norm 1.4301.
