ASTM A252 is the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder acts as a permanent load-bearing member or shell to form a cast-in-place concrete pile. The ASTM A252 specification has three grades: Grade 1, Grade 2, and Grade 3, of which Grade 2 and Grade 3 are commonly used materials.

Stainless steel pipe/tube is a kind of hollow long circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, machinery instrument and other industrial conveying pipes and mechanical structure components. In addition, the bending, torsional strength is the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for furniture kitchenware and so on.

Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is a kind of alloy steel that is not easy to rust, but it is not absolutely rust free. Stainless steel plate refers to the air, steam and water and other weak medium corrosion steel plate, and acid resistance steel plate is acid, alkali, salt and other chemical corrosion medium corrosion steel plate. Stainless steel plate since the beginning of the 20th century, has a history of more than 1 century.

ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11.
