ASTM a790 UNS s32205 pipe

What is ASTM A790 UNS S32205?

ASTM International, or American Society of Testing Material, has been a standards organization since 1902. For the past 120 years, it has offered over 12575 voluntary consensus standards for materials like pipes and tubes.

ASME, or American Society of Mechanical Engineers, with 85,000 members in 135 countries another standards organization from 1880. ASTM and SAE, or Society of Automotive Engineers 1972, started the UNS or unified numbering system for identifying the many alloys.

ASTM A790 UNS S32205 is duplex stainless steel with chromium-nickel-molybdenum-nitrogen, high strength, and resistance to corrosion up to 316 C or 600 F.

Is SA 790 UNS S32205 better than 316?

SA 790 UNS S32205 Tube and 316 tubes belong to the stainless steel family. ASTM 790 is better than 316 for the following, among other reasons.

  • A790 S32205 is a combination of austenitic and ferrite steels, whereas 316 is an austenitic alloy
  • UNS S32205 has a high content of chromium of 22 to 23% than the 16.5 to 18.5% in 316
  • A 790 has higher molybdenum content of 3 to 3.5 than 2 to 2.5 in 316 to is stronger.
  • A 790, with more corrosion resistance, is used in marine industries, and a 316, having lesser corrosion resistance, is best for food processing and brewery equipment, etc.

Is ASTM A790 Gr UNS S32205 super duplex?

Duplex steel with chromium-nickel-molybdenum evolved to super duplex steel. But the critical condition for it is to have chromium over 25% of its net quantity. Also, to have a PERN or pitting equivalent resistance number above 40. PERN is Cr+ 16 Ni + 3.3Mo number, and the more it is, the more the corrosion resistance.

ASTM A 790 Gr. UNS S32205 has only 22 to 23 % chromium to not have PERN above 40 to be only duplex steel rather than super duplex steel. Hence ASTM A790 Gr UNS S32205 Welded Pipe has all the excellent properties of duplex steel to be useful in many applications in several sectors.

Can you weld SA 790 grade UNS S32205 seamless pipe?

Though duplex steel is hard, it is easy to weld SA 790 Grade UNS S32205 seamless pipe using conventional methods. It includes MMAW or manual metal arc welding, GMAW or gas metal arc welding, GTAW or gas tungsten arc welding, and SAW submerged arc welding. Also, FCAW or flux cored arc welding, PAW or plasma arc welding, and highly effective laser and laser hybrid methods are best for welding ASTM A790 Seamless Pipe.

For choosing the proper welding methods for SA 790 Grade UNS S32205 seamless tube, it is essential to check many properties. It includes positional weldability, property requirements, productivity, etc.

What is the p number in ASME?

For the past 140 years, ASME or the American Society of Mechanical Engineers, has set standards for mechanical devices like pipes and tubes. ASME assigns P numbers for a group of metals and alloys with similar mechanical and weldability properties.

P numbers are alphanumerical designations by ASME for metals and alloys. The P numbers help buyers to know the brazing and welding procedure qualifications.

ASME provides P numbers or procedure numbers to help identify metals and alloys with essential properties for specific uses.

The ASME weld or P number for duplex and super duplex steel is 10H and for high chromium stainless steel is 10L. For high chromium and molybdenum steel, it is 10J, and for high chromium, molybdenum and nickel steel are 10K.

What are the four basic ASTM A790 welded pipe positions?

In the piping systems, it is only sometimes possible to weld in the same position as it involves many angles and other factors. It is because pipes and tubes may be in different positions, like in the corner, ceiling, floor and others. And welding may be essential for them in the as-it-is position. Many new techniques are now used to weld in any position using the correct methods.

The American Welding Society defines the four essential ASTM A 790 welded pipe positions as flat, overhead, horizontal and vertical.
