304 stainless steel round bar

304 stainless steel hot rolled round bar is the most versatile and widely used stainless steel. SS304 round bar is also known as 18/8 from the nominal composition of type 304 being 18% chromium and 8% nickel.

304 stainless steel round steel description:
1) Technique:Cold drawn or Hot-rolled
2) Size:5-500mm
3) Length:3m,6m or as required
4) Finish:Black,Pickled,Polish
5) Grade:201,202,304,304L,309S,310S,321,410,420,430,etc.

Appearance: long wood kind, and into the category of bar. Stainless steel round steel refers to the solid strip for uniform circular cross section of the stainless steel material, generally is about 6 meters long, its specifications expressed as a number of mm in diameter, such as "Φ 50" indicates that the diameter of 50 mm round steel. Surface: generally can be divided into 304 stainless steel circle of light (hereinafter referred to as: the light round 304, 304 light stick, or 304 stainless steel silver bar) and 304 stainless steel black circle (hereinafter referred to as: 304 black, or 304 stainless steel bar).

304 stainless steel circle of light, it is to point to the surface is smooth, after finishing, peeling or cold drawn polishing process; Commonly used in all kinds of chemical, food, textile and other mechanical equipment and decorative purposes. The so-called 304 stainless steel black circle or 304 stainless steel bar (black), refers to the black surface, directly after hot rolling, forging and annealing process, does not handle the oxide layer on the surface of the round steel.

304 stainless round steel application:
304 stainless steel is one of the most widely used chrome - nickel, stainless steel has good corrosion resistance, heat resistance, strength and mechanical properties at low temperature. Atmosphere in the atmosphere corrosion, if be industrial session or heavy pollution areas, you need to clean in time to avoid erosion.

304 stainless steel round steel according to the production process is divided into hot rolling, forging and cold drawn 3 kinds.

SS304 forged round bar specifications is 5.5 to 130 mm. Among them: 5.5-25 mm small 304 stainless steel round bar mostly to straight into a bundle of supplies, commonly used for reinforcement, bolt, and various mechanical parts; Or directly for the state of wire rod, for again after the processing of semi-finished products. Greater than 25 mm in 304 stainless steel round steel, mainly used in the manufacture of mechanical parts for seamless steel tube skelp or perforation.
