ASTM A403/ASME SA403 WP316/WP316L Stainless Steel Fitting 90 Degree Elbow Buttwelded B16.9
ASTM A403/ASME SA403 WP316L stainless steel elbow is a widely used pipe fitting in industrial piping systems. Its manufacturing and performance follow the ASTM A403 standard (standard specification for forged austenitic stainless steel pipe fittings), and the material grade is WP316L.
ASTM A403 Stainless Steel Buttwelded Fitting Classes for WP Grades
| Class | Construction | Nondestructive Examination |
| S | Seamless | None |
| W | Welded | Radiography or Ultrasonic |
| WX | Welded | Radiography |
| WU | Welded | Ultrasonic |
The chemical composition of 316L is mainly composed of 16-18% chromium (Cr), 10-14% nickel (Ni), 2-3% molybdenum (Mo), carbon (C) ≤ 0.03%, and the rest is iron (Fe) and a small amount of other elements (such as manganese, silicon, etc.). The low-carbon design of 316L can reduce carbide precipitation during use and enhance the product's resistance to intergranular corrosion.
316L is a low-carbon version of 316 stainless steel that performs outstandingly in high temperature, acidic, and chloride environments. It is more suitable for corrosive environments such as chemical, marine, and food processing. At the same time, due to its significant resistance to pitting and crevice corrosion, it is suitable for use in media containing chloride ions (such as seawater).
