Description
A20 steel applications and supply requirements
The technical record describes A20 for small, lightly loaded machined parts with complex geometry and high surface-quality requirements. Include the governing standard, delivery condition, product form, dimensions, tolerances, quantity and required documentation so the grade can be checked correctly.
Steel A20 is used: for the manufacture of small parts and machines, lightly loaded parts of complex configuration requirements of high dimensional accuracy and surface quality; after carburizing and cyanidation — lightly loaded parts, which are tejavanija wear resistance and high surface quality.
Note
Sulfur carbon steel high machinability.
