Stainless steel round bar besides having the characteristics of corrosion resistance has been developed over time to encapsulate end-user applications. For example, Improved Machining (IM) grades have been developed to enhance the machining of the steel into components, grades for hardness by responding to heat treatment, and grades with high corrosion qualities by adding additional elements to give it the characteristics desired.

 We stock a comprehensive range of grades, and sizes of stainless steel round bars to cover most machining and structural applications.

Grade  Description

303 grade represents the optimum in machining among the austenitic stainless steels. It is primarily used when production involves extensive machining. 303 is available in Improved Machining grade with machining characteristics significantly higher than that of the standard 303.

304 grade is dual-certified as grades 304 and 304L. Grade 304 is the standard "18/8" stainless. It has excellent forming and welding characteristics. Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components. 304 is available in Improved Machining grade with machinability significantly higher than that of the standard 304.

316 grade is dual-certified as grade 316 and 316L. 316 is the standard molybdenum-bearing stainless steel, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion-resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. 316 is available in Improved Machining grade with machinability significantly higher than that of the standard 316.

420 grade can be hardened by quench-and-temper heat treatment. It contains a minimum of 12 percent chromium, just sufficient to give corrosion resistance properties. It has good ductility in the annealed condition but is capable of being hardened up to Rockwell Hardness 50HRC, the highest hardness of the 12 percent chromium grades. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished. 420 is available in Improved Machining grade with machinability significantly higher than that of the standard 420.

431 grade is a heat-treatable martensitic, nickel-bearing grade that has the best corrosion resistance properties of all the martensitic grades. It has excellent tensile and torque strength, and good toughness, making it ideally suited to shafting and bolt applications. It can be hardened to approximately 40HRC. Because of its high yield strength, this grade is not readily cold-worked and is therefore not recommended for use in operations such as cold heading, bending, deep drawing, or spinning. 431 is available as an Improved Machining grade with machinability significantly higher than that of the standard 431.

2205 grade is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength.

UR52N+ grade is one of a group of "super duplex" grades, combining high strength with exceptional corrosion resistance. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. UR52N+ is also very highly resistant to pitting/crevice corrosion in high chloride, hot environments. Its duplex structure also results in excellent resistance to stress corrosion cracking.

Our stainless steel round bar is generally sold in the annealed condition, although some grades such as 17-4 or certain 400 series grades may be hardened by heat-treating. The standard length for most size round bars is 12’-14’ random lengths, but lengths are available in some sizes up to 20’ and longer. Finishes on bars can vary and include cold drew, centerless ground, smooth turned, rough turned, turned ground and polished, and HRAP.

Available Steel Grades: 304/304L, 316/316L, 302, 303, 309, 310, 321, 330, 347, 410, 416, 430, 600, 625, 718, 15-5, 17- 4, 17-7, A286, 2205 and more!
