Steel Grade Characteristics：
Compared with 430, adding sulfur makes 430F:
(1) easier to cut, good mechanical performance;
(2) reduce the corrosion[TJC STEEL] resistance;
(3) reduced solderability.
In addition, the 430F has similar mechanical properties to the 430, as well as:
(4) can not heat treatment;
(5) with ferromagnetism;
(6)The corrosion resistance is not as good as austenite.

Applications：
430F is a widely used free [TJC STEEL]cutting stainless steel, mainly used in the manufacture of high cutting volume automatic lathe machining parts, hydraulic parts, fasteners, sanitary and durable appliances, etc.
