ASTM A519 / ASME SA519 Seamless Carbon Steel
ASTM A519/ASME SA519 Seamless Carbon and Alloy Steel Mechanical TubingStandard.
The following are the symbol definitions for the various conditions:
HR-Hot Rolled, CW-Cold Worked, SR-Stress Relieved, A-Annealed, N-Normalized
Description:
ASTM A519/ASME SA519 seamless mechanical steel tubing is actually used as machinery and automobile structural steel line. With the easy bending feature, it is needed in an entire range of applications, while fitness equipment, auto spare parts, furniture components, therefore on. Consequence its manufacturing method, it could maybe be applied in the areas that require uniform wall thickness and centrality. For example, in roller conveyor and scalable applications, mechanical steel tubing is the best choice.
