1.What are the core principles and performance characteristics of interstitial steel (IF steel)?
Adding appropriate amounts of titanium (Ti) or niobium (Nb) to ultra-low carbon steel completely fixes the carbon and nitrogen interstitial atoms in the steel into carbonitrides, so that there are no free interstitial atoms in the steel.
Excellent formability, no aging, no yield plateau, suitable for stamping parts with complex shapes and particularly strict surface quality requirements.
2.What are the core principles and performance characteristics of non-aging ultra-deep drawing/extreme deep drawing steel?
Named according to the standards of companies such as Baosteel, its properties are similar to IF steel, exhibiting non-aging properties and excellent stamping performance.
BSUFD exhibits excellent stamping performance, with particularly superior deep-drawing and drawing properties, reducing the number of stamping passes.
3.What are the core principles and performance characteristics of aging-resistant low-yield steel?
Through metallurgical process control, the material has good resistance to aging and is less prone to slippage lines during stamping.
It has better stamping performance than ordinary low carbon steel and is less prone to tensile strain marks (slip lines).
4.What are the core principles and performance characteristics of steel used for general stamping?
Although some high-performance low-carbon steels do not completely eliminate interstitial atoms, they can still exhibit good resistance to aging in practical applications through process control.
It is suitable for general stamping and forming, and under normal storage and use conditions, the aging phenomenon is not obvious.
5.Overall, how was it?
If you require truly "timeless" steel, meaning that you don't need to worry about yield plateaus and tensile strain marks regardless of storage time or before processing, then IF steel (such as DC04 and DC06) and Baosteel's BUSD and BUFD are the best choices. They are mainly used in applications such as automotive panels and appliance housings where surface quality and formability requirements are extremely high.
