ASTM A210 is the standard covers seamless medium-carbon steel boiler and superheater tubes. ASTM A210 also covers minimum-wall-thickness, tubing sizes, boiler flues including safe ends, arch and stay tubes. ASTM A210 provides tensile and hardness properties but only applicable to certain size limitations. Material manufacturing shall be killed. Tubes shall be made by seamless process, marked as either hot-finished or cold-finished. Surface condition shall be specifically stated in the order. Chemical composition shall conform to the requirements. Elemental composition other than listed here shall not be permitted. Tension test, flattening test, flaring test, hardness test, hydrostatic or nondestructive electric test shall be made on specimens. Superheater tubes shall be formed without defects and shall withstand expansion, beading, forging, welding, and bending.
ASTM A210 seamless medium carbon steel pipe is applied for boiler pipe and boiler flue pipe with the minimum thickness, including safety end, vault, supporting pipe and super heater pipe.

The A335 pipes has a high level of Chromium and Molybdenum presence in it. While Molybdenum increases the overall strength, resistance, elasticity, hardenability and overall quality, moly ensures that the material is more resistant to softening, restrains the growth of grains and lessens the chances of embrittlement. It is the single additive that is responsible for the increase in high temperature resistance and it also improves the corrosion resistance to steel.

Bearing steel pipe refers to hot rolled or cold rolled (cold drawn) seamless steel pipe used for manufacturing ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180mm, and the wall thickness is 3.5-20mm, which can be divided into two types: ordinary precision and higher precision. Bearing steel is used to make balls, rollers and bearing rings. Bearing works under great pressure and friction, so bearing steel is required to have high and uniform hardness, wear resistance and high elastic limit.
The requirements for the uniformity of chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides of bearing steel are very strict. It is one of the most stringent steel grades in all steel production.
