430 Stainless Steel Tube

430 Stainless Steel Tube is one of the most versatile products on the market, offering numerous advantages over other tubing types. It can be used in a variety of applications due to its resistance to corrosion, heat and oxidation.

Chloride-induced stress corrosion cracking is much better tolerated by this steel than many ferritic steels, and it also stands up well in corrosive environments with dilute organic acids and alkalis. Furthermore, its resistance to nitric acid makes it ideal for chemical processing equipment like absorption towers, boiler drying equipment and acid tanks.

Grade 430 is an austenitic stainless steel with a body-centered cubic crystalline structure. Like all other stainless steels, it contains high levels of nickel and chromium for increased corrosion resistance.

430 stainless steel has the same machinability as its austenitic counterparts and can be machined through various processes like forging, cold drawing, deep drawing and upsetting; however it is not as easily forgeable as 301 or 304 stainless steel.

This steel is ductile in its annealed state and can be formed using various roll forming or mild stretch-bending operations. However, it should not be hot worked during this stage or allowed to cool slowly; otherwise, embrittlement may develop.

430 is renowned for its high tensile strength and large elongation. This is achieved through the quenching and portioning (Q&P) process, which involves combining ferrite, martensite, and retained austenite. The resulting mixed microstructure can improve tensile strength while the TRIP effect of retained austenite promotes elongation.
