301 stainless steel pipe/tube

301 Stainless Steel Pipe, often referred to as UNS S30100, which is a popular austenitic chromium-nickel stainless steel that is known for its corrosion resistance. To be considered Type 301, stainless steel must have a certain chemical composition that includes: Cr 16-18%, Ni 6-8%, C 0.15% max, Mn 2% max, Si .75% max, P 0.40% max, S .030% max. Type 301 Stainless Steel has a minimum tensile strength of 185,000 PSI and 140,000 PSI yield strength. All the Type 301 stainless steel pipe & tube we supply meets or exceeds the industry’s toughest standards. We also stock a wide range of Stainless Steel Pipes, Stainless Steel tube, 301 Stainless Steel Tubing, 301 Stainless Steel Seamless Tube, 301 Stainless Steel Welded Tube, SS 301 Tubing Bends, SS 301 Capillary tube, SS 301 heater tubes, other stainless steel pipe and grades also available in ready stock in standard lengths, but can be cut to size as per customer's requirement.

Product Details

Formability
Type 301 can be readily formed and drawn. Due to its high workhardening rate, intermediate annealing may be necessary for severe drawing and forming operations. Type 301 may not be suitable in certain severe forming applications where multiple forming operations are required.

Heat Treatment
Type 301 is non-hardenable by heat treatment. Annealing: Heat to 1900 – 2050 °F (1038 – 1121 °C), then water quench. Stress Relief Annealing: Heat to 500 – 900 °F (260 – 482 °C), then air cool.

Weldability
The austenitic class of stainless steels is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to avoid weld “hot cracking” by assuring formation of ferrite in the weld deposit. This particular alloy is generally considered to have similar weldability than the most common alloy of this stainless class, Type 304L Stainless Steel. A major difference is the high C content for this alloy, which can cause the weld heataffected-zones to be susceptible to intergranular corrosion in certain environments. When a weld filler is needed, AWS E/ER 308 is most often specified. Type 301 Stainless Steel is well known in reference literature.
