    (1) for TP304L and TP316L steel, carbon is not more than 0.015% for small diameter or thin wall or at the same time requiring a lot of cold drawing. The small outer diameter tube is defined as the tube with a diameter of less than 12.7mm, and the thin wall tube is a tube with an average wall thickness less than 1.2mm and a minimum wall thickness less than 1.1.
    The content of Si in TP316 tube should not be more than 1%.
    The Brinell hardness of seamless steel tube are listed in table 192HB, Rockwell hardness is lower than 90HRB, elongation of not less than 35%;
    (4) the unified standard of tensile strength is Rm, yield strength is Rpo.2Rm, and the elongation is A.
