What is 317 stainless steel pipe?
317 stainless steel pipe is a brand of stainless steel produced according to American ASTM standards. Equivalent to 0Cr19Ni13Mo3 stainless steel pipe in China. 317 contains 19% chromium, 13% nickel and 3% molybdenum.
317 stainless steel pipe has better corrosion resistance than 0Cr17Ni12Mo3, and is used as dyeing equipment material.
317 stainless steel pipe heat treatment: solution treatment (℃) 1010-1150 rapid cooling
Mechanical properties of 317 stainless steel pipe austenitic steel after solution treatment (GB/T4237-92)
317L stainless steel pipe, also known as UNS S31703 and Grade 317L SS pipe, it is a low carbon high grade stainless steel pipe, with a good corrosion resistance and machine work performance.
Compare to 317L, 317 stainless steel has a higher carbon content, it means that 317 stainless steel has a better heat resistance.
Kuaima Steel Co., Ltd. supply both 317 and 317L stainless steel pipe, and dual grade 317/317L is available based on the requirement to ASTM A312 or EN10216-5 etc.
317 stainless steel pipe production process
1. Hot rolled (extruded) seamless steel pipe:
Round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing (or reducing) → cooling → straightening → hydraulic test (Or non-destructive flaw detection) → mark → warehousing
2.Cold rolled (drawn) seamless steel pipe:
Round tube blank → heating → piercing → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening →Hydraulic test (flaw detection)→Marking→Warehousing.
Features of 317/317L Stainless Steel Pipe
In the point of chemical composition, the chromium, nickel and molybdenum contents of 317L stainless steel pipe are increased by 2%, 1%, and 1% compare to 316L stainless steel pipe. The threes are the main elements that determine the performance of stainless steel pipe. Reflected in the Pitting corrosion resistance, the performance of 317L stainless steel is better than 304L and 316L stainless steel.
The corrosion resistance of 317L stainless steel is similar to 316L stainless steel . The high molybdenum content ensures that it has a better resistance to overall and local corrosion for most media – such as sulfuric acid, acid chlorine and phosphoric acid. In strong oxidizing acids such as nitric acid, 317L stainless steel is susceptible to corrosion.
The performance of the 317L stainless steel is basically the same as 317 stainless steel. Due to the lower carbon content, the welding performance of 317L ss pipe and the intergranular corrosion resistance performance at high temperature (427~816 °C) are better than 317 ss pipe.
