It can be hardened to rockwell 58 hardness making it one of the hardest stainless steels.
Steel sheets graded.
The four most common aluminium grades available as sheet metal are 1100 h14 3003 h14 5052 h32 and 6061 t6.
Steel grades to classify various steels by their composition and physical properties have been developed by a number of standards organizations.
For example 1010 steel is a carbon steel with a nominal 0 10 percent carbon level.
A higher grade of cutlery steel with more carbon in it which allows for much better edge retention when the steel is heat treated properly.
According to the world steel association there are over 3 500 different grades of steel encompassing unique physical chemical and environmental properties.
5 7 grade 1100 h14 is commercially pure aluminium highly chemical and weather resistant.
On the other hand in the case of sae j403 grade 1008 the spec allows for up to 0 10 percent carbon with no minimum.
