SUY-1 is a mild steel with extremely low Carbon and low Impurities.
This grade is specified in "JIS C2504 Soft magnetic Irons", and is generally called "Pure iron".
SUY is classified into four types, from Type 0 (SUY-0) to Type 3 (SUY-3), depending on the value of magnetic properties.
Because of low carbon and Impurities, good drawability and soft magnetic properties
※, it is mainly used for motor applications. and recently, magnetic shielding application are also increasing.
※Magnetic properties include magnetic flux density and coercive force, which can be maximized by magnetic annealing again after cold working.
What is the difference between SUYP and SUYB?
In some cases, SUY is followed by P or B to indicate SUYP-1 or SUYB-1.
This means P: Plate (plate/strip/strip) and B: Bar (bar/wire), and is an expression of shape within the name of the steel grade.
Example: SUYP-1 = SUY-1 with the shape of P (Plate, Strip, Stripe)
