Stainless Steel Welded Pipe

Penn Stainless Products supplies welded pipe per ASTM A312 or ASTM A358 as well as rolled and welded. We supply common grades of stainless steel such as 304, 304L, 316, and 316L in standard pipe sizes and schedules, including Sch 5, Sch 10, Sch 40s and Sch 80s. We also cater to less common stainless welded pipe requirements with grades like 304H, 316H, 309S, 310S, 317L, 321H, 347H, 410, and 410S, in addition to Duplex and Nickel Alloy grades.

We can even produce products with wall thicknesses up to 3″ thick! Diameter sizes range from 1/4″ to 144″. We specialize in quick delivery of non-standard welded pipe, and all welded pipe products can be cut to size. Specialty testing, including x-ray, hydro testing and more, can be supplied upon request.

Stainless Steel Pipe & Tube Grades

Stainless 304/304L

With 18 percent chromium and 8 percent nickel, 304 is the most common stainless steel grade. 304L is the low carbon version of 304. All tubular products are readily available in 304 and 304L stainless steel Data Sheet Technical Question? Get a Quote

Stainless 304H

Like standard 304, this grade is also an 18 percent chromium and 8 percent nickel stainless steel. This grade requires a minimum carbon content of .04. The higher carbon content gives 304H greater heat resistant qualities, higher yield strength, and better short term and long term creep strength. Longer lead times could be required to deliver 304H in some tubular forms. Data Sheet Technical Question? Get a Quote

Stainless 316/316L

This grade has more nickel than 304 and 304L and includes molybdenum. 316 and 316L have superior corrosion resistance to 304 and 304L in most instances.  316 and 316L stainless steel is readily available in all product forms. Data Sheet  Technical Question?  Get a Quote

Stainless 317/317L

317 and 317L contain more molybdenum and has overall better corrosion resistance resistance than 304, 304L, 316, and 316L stainless steels. 317L offers higher resistance to chloride pitting compared 304L and 316L. 317 and 317L is available in seamless pipe. Other tubular products can be provided, but a larger lead time could be required. Data Sheet  Technical Question?  Get a Quote

Stainless 309

309 stainless steel has good strength and resistance to oxidation at high temperatures. This grade has better overall corrosion resistance than 304 stainless steel. Data Sheet  Technical Question?  Get a Quote

Stainless 309S

309S has lower carbon content than regular 309 and is recommended for applications where sensitization and subsequent corrosion by high temperature gases or condensates during shutdown may pose a problem. In some cases, tubular products may be dual certified to 309 and 309S. Data Sheet  Technical Question?  Get a Quote

Stainless 310

This grade combines excellent high temperature properties with good ductility. 310 stainless is designed for high temperature service applications. In most applications, 310 stainless resists oxidation at high temperatures.  Data Sheet  Technical Question?  Get a Quote

Stainless 310S

Stainless grade 310S calls for lower carbon content than standard 310 stainless. In many cases, 310 and 310S are dual certified. See full data sheet for comparison.  Data Sheet  Technical Question?  Get a Quote

Stainless 310H

Stainless steel grade 310H has higher carbon content and is often selected for high temperature applications. 310H is used in environments that produce sulfur dioxide gas at high temperatures.  Data Sheet  Technical Question?  Get a Quote

Stainless 321

321 Stainless Steel is an austenitic chromium-nickel stainless steel that contains titanium. This is best for use in welded parts that cannot be annealed. Data Sheet   Technical Question?  Get a Quote

Stainless 321H

321H grade stainless steel is the higher carbon version of grade 321. It possesses enhanced creep resistance and higher strength at temperatures above 10,000F (537°C). Usually, the plate’s carbon content allows dual certification. Data Sheet   Technical Question?  Get a Quote

Stainless 347

347 Stainless Steel is a stabilized austenitic stainless steel similar to type 304, but it also contains columbium and tantalum.  Data Sheet  Technical Question?  Get a Quote

Stainless 347H

347H Stainless Steel is a columbium-stabilized austenitic stainless steel plate. It has good general corrosion resistance, as well as slightly better resistance in strong oxidizing conditions than grade 321. Data Sheet   Technical Question?  Get a Quote
