FAQ
Frequently Asked Questions
No. Stainless steel is defined by its chromium content for corrosion resistance. Soft steel is defined by its low carbon content for malleability. They are different classifications.
Yes, through a process called carburizing (adding carbon to the surface) or by alloying it with other elements, its hardness can be increased, though it then ceases to be 'soft' steel.
It is extensively used in car body panels, wire, nails, pipes, and structural sections (like I-beams) where formability and weldability are more important than extreme hardness.
It creates a cognitive dissonance. 'Steel' connotes strength and permanence, while 'soft' undermines it. This perfectly encapsulates the idea of something that appears durable or resolute but has a fundamental, yielding weakness.
