Product Details

Grade 430F is a Martensitic free-machining stainless steel based on 430 stainless steel. By adding the element sulfur, free cutting 430F steel has good machinability and small friction coefficient and has been mainly used in automatic lathe, electronic components and various pump valve compressor parts, but not recommended for high temperature and below zero use. Similar to 430, 430F is ferromagnetic, the addition of sulfur element makes 430F easier to cut with good machining performance but reduced weldability and corrosion resistance compared with 430.
