304/304L (UNS S30400 & UNS S30403) are austenitic alloys of stainless steel bars. Stainless Steel Round Bars have many great attributes. They are hard, strong, and have excellent anticorrosive properties,excellent mechanical properties.
304/304L Stainless Steel Round Bar is useful where sanitation and cleanliness are important. Non magnetic in the annealed condition. Hardness and tensile strength can be increased by cold working, but modified by lowered carbon content providing good resistance to corrosion in welded construction where subsequent heat treatment is not practical.
Grade 304L (L= low carbon) is the same as the 304 except it has an extra-low-carbon analysis, the advantage of which is that it precludes any harmful precipitation in the 800º F to 1500º F range, such as might otherwise occur in welding heavier sections.

Grade 304 is the most popular grade of Stainless Steel. These round bars are easily TIG, ARC & MIG welded and they can also be brazed. Although Grade 304 is not the Free Machining grade of Stainless Steel (Grade 303 is best suited for machining), it can be machined under the correct conditions. Sharp tools are required, and correct speeds & feeds are very important – taking care to ensure that cuts are deep enough to clear the surface is a must, as excess contact will work harden the material.
The attributes mentioned above make Grade 304 Stainless Steel Rod a fabricators favourite – often used in the manufacture of security grills, frames, tools, shafts, gears and items as required by the construction industry.
The other advantage of Grade 304 Stainless Bar against Grade 303, is that it is very slightly harder and also has better anti corrosive properties. Because of this, Grade 304 Stainless Steel Bar is heavily used in the manufacture of fasteners & fixings such as nuts, bolts, washers, clips, fittings & clamps. Items in the fastener industry that are manufactured from Grade 304 Stainless Steel are often referred to as “A2”.
