About stainless steel 430

Chemical formula

Including Fe (Iron), <0.12% C (Carbon), 16-18% Cr (chromium), <0.75% Ni (nickel), <1.0% Mn (Manganese), <1.0% Si (silicon ), <0.040% P (Phosphate spectrum), <0.030% S (sulfur)


430 stainless steel is a low-strength steels containing chromium and ferritic steels belong to the group. This steel is known for its resistance to corrosion and easily shaped, has a low coefficient of expansion, and is resistant to oxidation good. It can be used in certain applications because chemical resistance to withstand nitric acid.


430F stainless inox is usually provided in the form of bars used in automatic screw machines.

Grade 434 (inox 434) with similar features stainless steel, although it is a form version of Molybdenum (very hard transition metal and silvery white). Molybdenum improve its corrosion resistance.


The following sections provide information for the key attributes of stainless steel 430 stainless steel coils, stainless steel pipes and stainless steel sheets – according to ASTM A240 / A240M.


All kinds of steel, such as 430 stainless steel lines, with an outstanding wear protection. 430 stainless steel is resistant to corrosion by organic acid and nitric acid. Achieving optimal corrosion resistance in strictly controlled conditions. Wear resistance of its groove and holes are very similar Inox 304. 430F stainless steel is no sulfur type are machined so anticorrosive features grooves and holes are relatively lower than the type of machine not through outsourcing.

430 stainless steel is resistant to oxidation up to 870 ° C (1598 ° F) when used continuously disrupted, and up to 815 ° C (1499 ° F) in continuous use. At room temperature, it tends to become brittle, especially when it has been heated for a long time in the range 400-600 ° C (752-1112 ° F). This problem can be remedied with annealing.


Solution annealing may be done by heating to 815-845 ° C stainless steel 430 (1499-1553 ° F). Then, metallurgical cooling it to 600 ° C (1112 ° F) followed by air-cooled fast – slow cooling between 540 and 400 ° C (1004, 752 ° F) tend causing embrittlement.

For the critical annealing, heating should be conducted at 760-815 ° C (1400-1499 ° F), followed by the use of chiller or water cooled.
