. Not all steel is attracted to magnets as-is.
All steel will show varying degrees of ferromagnetism, meaning almost all steels can be magnetized with some work. Once magnetized, a steel will be attracted to (or repelled from) a magnet if the magnet is strong enough.
There are many types of steels. Some have higher chromium contents than others, and all have varying mechanical properties which combined will change the magnetic permeability of the steel. Some steels are magnetic after casting or machining, others are not. Some steels can have their magnetic properties altered significantly by mechanical processing. This means that some steels will show little or no response to a magnetic field, while others will show a large response, and that this response can be changed by altering the hardness of the steel (mechanical hardness and magnetic hardness are directly related because both depend on how defects move through the material microscopically).
