Technical purpose and scope of ASTM A511
The ASTM A511 standard regulates the production and supply of seamless stainless steel mechanical tubing intended for use in machinery equipment assemblies. This metal product from EV Group China is optimal for manufacturing hollow parts of complex configuration, including nozzles, transition elements, and couplings subjected to machining. The material is in high demand for projects where high corrosion resistance and the preservation of strength characteristics at elevated temperatures are critical.
The specification covers seamless tubes obtained by cold or hot working methods. The permissible outside diameter for round tubes is up to 12 3/4 inches (325 mm). EV Group China supplies rolled products with specified wall thickness or inside diameter parameters in accordance with customer drawing requirements.
The products are supplied in various geometric shapes: round, square, rectangular, or special sections. For the production of hollow billets for further machining, only round profile tubes are permitted.
When placing an order with EV Group China, clients can specify additional requirements for quality control and heat treatment. The values stated in inch-pound units are the standard, while metric values in parentheses are provided for reference purposes. The use of measurement systems should be carried out independently of each other.
