The ASTM A249 specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels. More specifically, the ASTM A249 specification is intended for uses such as Boiler Superheater heat exchanger condenser tubes be furnished in the heat-treated condition in accordance with the required solution temperature and quenching method. conform to the prescribed tensile and hardness properties such as tensile strength, yield strength, elongation, and Rockwell hardness number. undergo mechanical tests such as tension test, flattening test, reverse-bend test, hardness test, and hydrostatic or nondestructive test.
Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration. Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe. Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes. It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.

Polished 304 Stainless Pipe is a standard stainless pipe that has been polished to a 180 Grit Brushed Finish on its exterior for cosmetic and ornamental applications. Unlike the dull mill finish of standard stainless pipe, this polished stainless steel pipe allows your projects to have a more finished look with excellent corrosion resistance making it ideal for handrails, architectural design, restaurant and store fixtures, trade show displays, marine components and more. Just like standard stainless pipe it has an interior weld seam. SPECIFICATIONS: Type 304/304L Welded, ASTM A312 FINISH: 180 Grit Polish, Brushed Finish CHARACTERISTICS: Welding = Excellent Machining / Grinding = Fair Bending / Forming = Good Wear Resistance = Excellent Corrosion Resistance = Excellent MECHANICAL PROPERTIES: Tensile Strength = 85,800 psi Yield Point = 34,000 psi Elongation = 60% in 2" ; Elasticity = 29,000 ksi Shearing Strength = 11,500 psi Brinell Hardness = 170; Density = .289 lb/in AVAILABLE LENGTHS: 4ft. 6ft, 8ft, 10ft, 20ft, or Cut to Size
