Stainless Steel is a metal made up of certain materials like Chromium up to 18%, Carbon 0.8%, Manganese 2%, Nickel 8%, Silicon, Molybdenum, etc. in certain proportions. It is the attribute of Nickel that the metal is resistant to several conditions and Carbon helps it out in sustaining the strength whereas chromium imparts the property to the metal and Molybdenum provides corrosion against scales. So, the Tubes made up of Stainless Steel are of course lightweight but are very durable and stronger and most importantly are resistant to various fluids and chemicals which makes them optimum to be used in the piping system. There are several grades of stainless steel used for manufacturing the products and each grade is categorized into series like series Series 200, Series 300, Series 400, Series 500, and Series 600, etc. these are just series that include further grades. The Stainless Steel products are also made up of several other grades of SS like SS 304, SS 304L, SS304H, SS 316, SS 316L, SS 316H, SS 317, SS 317L, SS 32L, SS 32LH, SS 408, SS 409, SS 410, SS 416, SS 420, SS 430F, SS 440, SS 630, etc.
Stainless Steel 430
Belonging to series 400 of Stainless Steel, Grade 430 is ferritic stainless steel. The chromium in 430 is 17.5% and carbon is 0.17%, there is an absence of nickel however molybdenum is 0.6% at maximum in this grade. The Ultimate Tensile Strength of 430 grade is 79800 psi and Yield Strength is 29000 psi. the grade 430 is said to have much more corrosion resistance than any other grade of SS. Due to its good properties, grade 430 is used for manufacturing many products. Mainly after forging the alloy, it is usually stored in shapes like rods, bars, sheets, plates, coils, etc. the rods are long and simply circular whereas the bars are long as well but they are square or rectangular.
The rods and bars are mostly used as it is however different products are also manufactured using the rods and bars. The rods and bars are melted and cut into pieces for making pipe fittings and fasteners for industrial and commercial uses. Just like any other grade even 430 is used for many other things be it household or industrial purposes.
Applications of SS 430
The 430 grade has great immunity against corrosion so it is mostly used in plants and industries. The Petroleum Refinery uses Stainless Steel 430 round bars for making it into pipes and using it to convey the crude oil to the plant for converting it. The Boilers use this grade for outer covering because it can withstand steam and fluids or any substance. The pipelines use pipes made of grade 430 because they can survive water for a long period of time. Cooling towers also use this alloy because of its resistance against water and steam for the very same reason it is also used in making steam exhausts. The Electric Generation plants use this alloy grade because it is compatible with electricity. Paper Production, Waste Treatment, Pharmaceutical, and Food Processing equipment make use of SS 430 in all shapes and sizes.
