Hastelloy C276 Round Bar, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Hastelloy has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard Asme Sb574 Hastelloy C276 grades.
Asme Sb574 Hastelloy C276 Square Bar is the solid rod which has the cross-section of a Alloy C276 Cold square and a round bar is the rod which has the cross section of a circle. In other words, draw a Hastelloy C276 solid square and extrude it up to some particular length. The resultant rod, can be assumed as a Astm B574 Hastelloy C276 Round Bar. In the same way, draw a circle and extrude it. The resulting rod can be assumed as a round bar
Benefits of Hastelloy
Good stress corrosion cracking resistance (SSC)
Good ductility and toughness
Greater tensile and yield strength
Improved corrosion resistance in comparison to Hastelloy C276 Round Bar
Opportunity for purchases to reduce their material costs without compromising on quality
