AISI 430 Ferritic Stainless Steel Chemical Composition & Properties, Grades, Chart and Online Pdf

AISI 430 is wide-spread ferritic grade of stainless steel appreciated for its high level of corrosion resistance, besides the ability to withstand high temperatures, and be easily fabricated. The chemical formula generally includes 16-18% of chromium, with lower than 0.12% carbon amount, together with microscopic amounts of manganese, silicon, phosphorus, sulfur and iron. As a consequence the wear resistance of the coating in a broad range of conditions is evident, in particular in the mildly corrosive environment. AISI 430 is frequently acquired for appliance construction in kitchens, automotive accessories and even architectural embellishments. Its magnetic properties are what enable it to be used in the production of electromagnetic gadgets. Engineers and designers usually consult and use official tables, charts and online manuals pdf that specify its mechanical characteristics, grade and possible applications when considering material choice.

AISI 430 Ferritic Stainless Steel Chemical Composition And Grade Table

AISI 430 ferritic stainless steel is acclaimed for its corrosion-resisting performance as well as its affordability, which is why it is in demand in different sectors of industry. The main components are iron (Fe), crushed stone, chromium (Cr) and small ratios of carbon (C) and manganese (Mn), among some others. Normally, it has the proportion of 16-18% chromium being the main factor that makes it resistant to oxidation and corrosion. AISI 430 is classified in 400 series of stainless steels which combine magnetic properties and versatility for medium corrosion resistance and effective formability.
