BA finish 430 stainless steel coil
Stainless steel grade 430 is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels.
This steel is known for its good corrosion resistance and formability, coupled with practical mechanical
properties. It can be used in certain chemical applications due to its resistance to nitric acid.
Grade 430F stainless steel is usually provided in bar form to be used in automatic screw machines.
Grade 434 has similar properties as grade 430, although it is a molybdenum-bearing version. The molybdenum content enhances its corrosion resistance.

The machin ability of stainless steel grade 430 is a lot easier than standard austenitic steels such
as grade 304 but there is a chance for galling. Lightly drawn bars are easier to machine than bars
in the annealed condition. Grade 430F is easy to machine.
Stainless steel grade 430 has a low work hardening rate which enables easy bending and forming.
The low ductility rate, however, makes it difficult to perform very rigorous operations. It is possible
for grade 430 wire to handle rigorous cold heading. Sub-critical intermediate annealing may be required for extreme cold working.
The following are the applications for stainless steel grade 430:
Dish washer linings
Refrigerator cabinet panels
Element supports and fasteners
Stove trim rings and chimney liners
Automotive trim and lashing wires
The key application of grade 430F is in repeatedly used machined parts.
