Specifications for Manufacturing Stainless Steel Round Tubes:


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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Stainless 347

347 Stainless Steel is a stabilized austenitic stainless steel similar to type 304, but it also contains columbium and tantalum.

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.
