ASTM A312
SEAMLESS AND WELDED PIPES FROM ABSTENITIC STAINLESS STEEL
The pipes are designed for use under high temperatures and for general usage in high-corrosion media. The pipes are manufactured from materials TP 304L, TP 304, TP 316Ti, TP 316 L, TP 321.
The range of size is given in Table 52. The chemical composition is given in Table 53. The mechanical properties are given in Table 54. DIN to GOST steel specifications conversion data are given in Table 55.
