What is 309S and 309H Stainless Steel Pipe?

Description of 309S / 309H Stainless Steel Pipe

Alloy 309 (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C). A chromium-nickel stainless grade, Alloy309/309S is suitable for a number of high temperature applications. 23% chromium, approx. 5% more than 304 stainless steel gives Alloy 309/309S an edge over 304 stainless steel when it comes to general corrosion resistance at elevated temperatures.

AISI 309S stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 309S is the AISI designation for this material. S30908 is the UNS number. It contains less nickel in its composition than Type 310, moderately low tensile strength and  lower amount of carbon in its composition among the wrought austenitic stainless steels thus utilization in areas where high temperature gases may pose a problem. Type 309S is additionally characterized by its resistance to oxidation and creep, along with its ability to withstand high temperatures. Moist environments have no effect on it, due to the higher levels of nickel and chromium in its makeup. Because of this, it is often utilized in marine environments in place of Stainless Steel 304, as it displays a higher resistance.
Despite its excellent weldability, Type 309S does have a tendency to work harden.

AISI 309H (S30909) Stainless Steel. AISI 309H stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 309H is the AISI designation for this material. S30909 is the UNS number. It has a moderately low tensile strength

What is the Difference Between Stainless Steel 309S and 309H?

Alloy 309 (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C). Because of its high chromium and low nickel content, Alloy 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). The alloy is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. Alloy 309 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced.

When heated between 1202 – 1742°F (650 – 950°C) the alloy is subject to sigma phase precipitation. A solution annealing treatment at 2012 – 2102°F (1100 – 1150°C) will restore a degree of toughness.

309S (UNS S30908) is the low carbon version of the alloy. It is utilized for ease of fabrication. 309H (UNS S30909) is a high carbon modification developed for enhanced creep resistance. It most instances the grain size and carbon content of the plate can meet both the 309S and 309H requirements. Alloy 309 can be easily welded and processed by standard shop fabrication practices.

Properties and Processing Characteristics of Stainless Steel 309S / 309H

SS 309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance. The lower nickel content of CS309 improves resistance to sulphur attack at high temperatures.

SS 309 provides excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures. The alloy is non-magnetic as annealed and becomes slightly magnetic when cold worked.

Processing

Standard welding processes for this steel grade are:

  •  TIG-Welding
  •  MAG-Welding Solid Wire
  •  Arc Welding (E)
  •  Laser Beam Welding

In quenched condition the material can be slightly magnetizable. With increasing cold forming the magnetizability increases. Heat resisting tubes are delivered regarding testing in accordance to DIN EN 10216-5 respectively DIN EN 10217-7. In Germany, SEW 470 still applies for heat resisting tubes.

Fabrication Data

Alloy 309 can be easily welded and processed by standard shop fabrication practices.

Hot Forming

Heat uniformly at 1742 – 2192°F (950 – 1200°C). After hot forming a final anneal at 1832 – 2101°F (1000 – 1150°C) followed by rapid quenching is recommended.

Cold Forming

The alloy is quite ductile and forms in a manner very similar to 316. Cold forming of pieces with long-term exposure to high temperatures is not recommended since the alloy is subject to carbide precipitation and sigma phase precipitants.

Welding

Alloy 309 can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.

Corrosion Resistance

Wet Corrosion
Alloy 309 is not designed for service in wet corrosive environments. The high carbon content, which is present to enhance creep properties, has a detrimental effect on aqueous corrosion resistance. The alloy is prone to intergranular corrosion after long term exposure at high temperatures. However, due to its high chromium content (23%), Alloy 309 is more corrosion resistant than most heat resistant alloys.

High Temperature Corrosion
Alloy 309 resists high temperature corrosion in most in-service conditions. Operating temperatures are as follows:

Oxidizing conditions (max. sulfur content – 2 g/m3)
1922°F (1050°C) continuous service
2012°F (1100°C) peak temperature

Oxidizing conditions (max. sulfur greater than 2 g/m3)
1742°F (950°C) maximum temperature

Low oxygen atmosphere (max. sulfur content – 2 g/m3)
1832°F (1000°C) maximum temperature

Nitriding or carburizing atmospheres
1562 –1742°F (850 – 950°C) maximum

The alloy does not perform as well as Alloy 600 (UNS N06600) or Alloy 800 (UNS N08800) in reducing, nitriding or carburizing atmospheres, but it does outperform most heat resistant stainless steels in these conditions.
