Are you looking for an alloy with high strength, hardness, and corrosion resistance? If so, you might want to think about using stainless steel of type 429. This metal has exceptional workability, formability, and resistance to oxidation at higher temperatures thanks to its low carbon content and columbium addition. Let's examine this intriguing alloy in more detail.
429 Stainless Steel Composition
Type AISI 429 stainless steel comprises 11% chromium, 1% manganese, and.2% nitrogen in addition to being primarily composed of iron, chromium, and nickel. It also has trace amounts of carbon, sulphur, and other elements, as well as very minute levels of silicon (.75%), phosphorus (.04%), and other elements. The enhanced strength and corrosion resistance of this metal are due to the columbium addition.
429 Stainless Steel Physical Properties
A wide range of diameters are available for UNS S42900 in both cold-rolled (CR) and hot-rolled (HR) forms. Its ultimate tensile strength is 75 ksi, while its tensile yield strength is 70 ksi. Depending on its condition, AISI type-429 stainless steel has a Brinell hardness value that ranges from 164 to 193. At 68°F (20°C), it has a thermal conductivity of 14 BTU/hr-ftF and an electrical resistance of 740 microhm-Cir-mil/ft.
429 Stainless Steel Mechanical Properties
This alloy is suitable for a variety of applications, including fasteners, shafts, pump parts, and more, because to its exceptional combination of mechanical qualities. In contrast to other metals like nickel alloys or titanium alloys, it may be formed more easily because of its low work hardening coefficient. It can also be welded, although particular welding techniques are needed to guarantee effective heat treatment after welding for the highest levels of corrosion resistance.
