ASTM A314 Grade 316 Introduce
ASTM A314 Grade 316 has a lower carbon content than other types of stainless steel, making it suitable for a wide range of uses. It has excellent ductility, high tensile strength, and superb malleability. In terms of formability and weldability, ASTM A314 Grade 316 can be either hot or cold worked depending on the specific requirements. When hot worked, it has good formability and can be bent, drawn, or spun. Its weldability is excellent and can be welded without preheating and without the need for filler materials. The applications of ASTM A314 Grade 316 include tanks, pumps, fittings, chemical processing equipment, and storage vessels. It can also be used in heat exchangers, piping systems, heat treating equipment, and fittings. Moreover, the grade is used extensively in the chemical processing industry, such as for distillation, drying, and chemical storage tanks.
Smelting temperature:1216°C - 1625°C
Application:Specification for stainless steel and steel rods for forging and heat
