Navgraha Steel & Engg Company is established in the manufacturing and distribution of different grades pipes. ASTM A 312 TP 304 Pipes are widely known for its high-temperature capability and wide corrosive surroundings resistance. It is austenitic structured with excellent fabrication capabilities. These are formed with standard ASTM A 312 includes seamless and welded pipe manufacture. These pipes are constructed with SS 304 grade with low carbon SS 304L and high carbon SS 304H grades. It is availed in diverse sizes, thicknesses, and diameters according to standards as well as custom-sized.
What are the features of Stainless Steel ASTM A 312 TP 304/304L/304H?
• Austenitic Stainless Steel
• Stronger, Extra Corrosion Resistant
• High Toughness
• Wide Temperature Ranges with Cryogenic Level
• Greatly Formable
ASTM A 312 TP 304 Pipes are highly tough and anti-corrosive with excellent formability of the material. It is accurately formed in different shapes like hex, round, and hydraulic. These Pipes are delivered in bright annealed or annealed pickled, polished form. Furthermore, these are classified as seamless, ERW, Welded, Fabricated, and grooved pipes. We offer excellent surface finished pipes widely used in the fabrication and processing industries.
ASTM A 312 TP 304 Pipes are durable and formable. These Pipes are easily welded with common techniques and provide higher yield and tensile properties at high stress. Its capability of pressures is specified with class, and high as well as low-pressure systems exercise these pipes.
ASTM A 312 TP 304 pipes are efficient due to:
• Advanced General Corrosion, Oxidization Resistance
• Comprehensive Tensile Strength
• Enormously Durable
• High-Pressure Capability
Industrial Applications of ASTM A 312 TP 304/304L/304H pipes:
• Water Systems
• Sinks and Refrigerators
• Textile Industry
• Beverages and Food Industry
• Sanitary Systems
• Cryogenic applications
ASTM A 312 TP 304L Pipes are less expensive and low carbon pipes enhanced with resistive properties against corrosion. The Schedule of pipe describes wall thickness, and it is perfectly matched with the system schedule due to the accuracy of dimensions.
ASTM A 312 TP 304H Pipes contains higher carbon value increasing strength and heat resistance. It offers excellent strength to short and long creep effects. At the same time, improvement of tensile properties along with yield is also obtained in these pipes.
