Maraging 250 Chemical Composition & Properties, Grade, Tables and Online Pdf
Maraging 250 is an alloyed steel with the most outstanding properties, mostly employed within aerospace and defense, known as high-strength steel. The general make up varies from one to another and it usually contains elements such as iron, nickel, cobalt, molybdenum, titanium, aluminum and carbon. Showing outstanding strength, hardness, and resistance to corrosion and much higher than that of 304, maraging 250 has great capacity to not be degraded even at high temperatures. It is work-hardenable, providing finesse in setting the required mechanical properties. The University of Calgary offers five CAA courses; they are CAA 6172, CAS 6173, CAS 6174, CAA 6281, and CAS 6281. Charts that describe its mechanical properties, like tensile strength, yield strength, and elongation at the max, can be in the technical datasheets. Online resources gives a full description and has downloadable PDFs with more details on the composition, properties and applications of Maraging 250 in different industries.
Maraging 250 Chemical Composition And Grade Table
Maraging 250 is a very high strength steel alloy usually praised for its superlative strength-to-weight ratio and toughness. Its chemical make-up generally contains among 70% iron (and around) 18% nickel (around), 8% cobalt (about) 4% of molybdenum and 1.8% of titanium (approximately) and traces of other elements such as carbon (approximately), silicon, manganese, sulfur and phosphorus. Maraging 250 can hence achieve superior performance in terms of tensile strength and corrosion resistance, and weldability too is excellent with this material. The grade table presented herein is a comprehensive guide for the engineers that features mechanical properties, heat treatment methods, and uses in aerospace, automotive and tooling sectors.
