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.
