ASME SA312 and ASTM A312 Standard
ASME SA312 and ASTM A312 are standards set by the American Society of Mechanical Engineers (ASME) and the American Society for Testing and Materials (ASTM), respectively. These standards establish the specifications for seamless, welded, and heavily cold-worked austenitic stainless steel pipes suitable for high-temperature and general corrosive service.
The "Gr TP304" designation refers to the specific grade of stainless steel, which, in this case, is TP304. TP304 is a widely used grade known for its excellent corrosion resistance, high-temperature strength, and good mechanical properties. Werkstoff 1.4301 AISI 304 falls under the austenitic stainless steel category, making it suitable for a variety of applications, including those in the chemical, petrochemical, and food processing industries.
