The Formation Mechanism and Improvement Measures of Red Rust Iron Oxide Skin of Hot-Rolled Steel Plate |
|
|
|
Abstract Macro-morphology, thick, micro-chemical composition, structure and the mass percent content of O / Fe of the surface iron oxide skin of automotive beam steel were investigated by samples collected in factory. We analyzed the cause the surface iron oxide skin of automobile beam steel, and also proposed a solution. Large quantities of industrial production and feedbacks of users explain that products with smooth surface and excellent stamping performance can fully fully satisfy the application requirements of automotive longitudinal beam and beam.
