ASTM A789/A789M:

• This standard covers the manufacturing requirements for stainless steel and other austenitic stainless steel straight and spiral seam pipes.
• Pipes are typically used under general service conditions and are suitable for general corrosive environments and low or high-temperature service.

 

ASTM A790/A790M:

• This standard covers the manufacturing requirements for duplex (austenitic-ferritic) stainless steel seamless and welded pipe.
• Pipes are usually used in high-temperature, high-pressure, or corrosive environments with higher corrosion resistance and mechanical strength.

The key differences are the type of material and application area of the pipe. ASTM A789/A789M generally covers austenitic stainless steels and applications under general service conditions, while ASTM A790/A790M covers duplex stainless steels and more severe service environments and requirements. The choice of which standard to use depends on the specific project's needs, including required pipe material properties, working environment conditions, and budget, among other factors.
