420 Stainless Steel Bar
We’ve recently announced the addition of 420 Stainless Round Bar to its inventory. 420 is a 12% chromium, martensitic stainless steel. 420 provides improved hardenability and strength compared to 410 stainless. 420 stainless bar inventory meets DFARs sourcing requirements.
“With the addition of 420 stainless, we now offer more than 20 grades of stainless bar spanning every family from 300 & 400 series to duplex and precipitation hardening (PH) grades. Expanded inventories combined with our industry leading website and processing capabilities furthers our mission to be the easiest metals sourcing option.”
17-4 Flat Bar
17-4 stainless is an age-hardening martensitic stainless combining high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short-time, simple low-temperature treatment. Unlike conventional martensitic stainless steels, such as type 410, 17-4 is quite weldable. The strength, corrosion resistance and simplified fabrication can make 17-4 stainless a cost-effective replacement for high strength carbon steels as well as other stainless grades.
Our bar processing options include precision sawing, band sawing, ink jet part marking, and XRF positive material verification.
We offer a diverse grade and product form portfolio of heat and corrosion resistant alloys across 13 locations in North America and Asia, with additional representation in Europe. Click here to learn more about us.
