ASTM A210 Specification for Seamless Carbon Boiler Tubes

ASTM A 210 covers seamless steel boiler tubes and superheater tubes, which are medium carbon tube products. Product types include safe end tubes, minimum wall thickness arch tubes and support tubes, and tube sizes. Materials manufacturing was stifled. The manufacturing method follows a seamless process and the final product can be hot or cold worked. Surface conditions can be customized according to your requirements. Test requirements: tensile test, flattening test, expansion test, hardness test, hydraulic or non-destructive electrical test, etc.

Delivery status: annealed, normalized, normalized and tempered
Surface treatment: oil immersion, varnish, passivation, phosphating, shot blasting
Usage: Suitable for high, medium and low pressure boilers and other pressure applications
