Piyush Steel is a well-known manufacturer of Stainless Steel TP 309 Pipes, which is superior to 304 stainless in both strength and corrosion resistance. SS 309 Tubes is known for good strength and oxidation resistance in continuous service temperatures up to 2000 Degree F (1093 Degree C). Stainless Steel UNS S30900 Pipes and Tubes do not react to heat treatment. Strength and hardness of Alloy 309 Pipes can be increased by cold working. Alloy 309 Tubes cannot be hardened through heat treatment because it consists solely of austenite at room temperature. Stainless Steel Din 1.4301 Seamless Tubing has higher tensile and yield strengths that can be obtained through cold working and not followed by full annealing are not stable at the higher temperatures where these alloys are used. AISI 309 Pipes are essentially nonmagnetic as annealed and become lightly magnetic when cold worked. Buy TP309 Stainless Steel Pipes at reasonable cost from us.
TP309 Stainless Steel Tubing are austenitic chromium-nickel stainless steels that provide excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures. The lower nickel content of AISI 309 Tubes improves resistance to sulphur attack at high temperatures. The high chromium and nickel content of SUS 309 Pipes provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304.
Austenitic Grade 309 Pipes are often used in Furnaces — burners, doors, fans, piping and recuperators; Fluidized Bed Furnaces — grids, piping, wind boxes; Paper Mill Equipment; Petroleum Refining — catalytic recovery systems, recuperators. These Austenitic Grade 309 Tubes are also used in Power Generation — pulverized coal burners, tube hangers; Thermal Processing — annealing covers and boxes, burners grids, doors, fans, lead pans and neutral salt pots, muffles and retorts, recuperators, walking beams; and Waste Treatment — incinerators, rotary kilns and calciners.
We Supply SS 309 Pipes & Tubes of various origin’s and companies like Nippon Steel & Sumitomo Metal, Sandvik, Sanyo Special Steel, Kobe Steel, Schoeller Bleckmann, Salzgitter Mannesmann Stainless Tubes, Tubacex etc.
Which Is Better 304 or 309 Stainless Steel Pipe?
304 stainless steel is an austenitic steel, meaning it is non-magnetic and has a low carbon
content. On the other hand, 309 stainless steel pipe is ferritic steel, which means it is
magnetic and has a higher carbon content. Both types of stainless steel have good corrosion
resistance, 309 stainless steel is better suited for high temperature applications while 304
stainless steel is a more general-purpose alloy that is widely used.
Can 309 Stainless Steel Be Hardened by Heat Treatment?
309 stainless steel pipe is a heat resistant stainless steel, but it cannot be hardened
through heat treatment like some other types of stainless steel. It is a stainless steel alloy
that has a high resistance to corrosion and high temperature. 309 stainless steel properties
are typically used in applications where high temperature corrosion resistance is needed. 309
stainless steel pipe can be hardened through a work hardening process like cold working, but
not through heat treatment.
