Nestled in the industrial heart of Manila, Philippines, Diaz Sheetsandplates has built a solid reputation as a trusted partner for high-grade metals. We take pride in supplying locally and across the archipelago with top-tier Stainless Steel 446 Sheet and Plates. Our commitment is to provide not just a product, but a reliable solution, backed by deep industry knowledge and a dedication to quality that our customers have come to expect for their most demanding projects.
This unique stainless steel is primarily composed of iron, with a significant chromium content of 23-27% and a higher than usual manganese level. Its key characteristic is an excellent resistance to corrosion and oxidation under high temperatures, reaching up to 1400°F. While not as tough as some other alloys, this plate maintains good strength and durability, offering a cost-effective solution for environments where heat is a primary concern, without the need for additional nickel.

Stainless steel 446 sheets and plates have many advantages, making them ideal for high temperature applications. They provide exceptional resistance to oxidation, corrosion and scaling, even in extreme environments. The high chromium content increases the ability to withstand high temperatures and increases durability. These materials also provide excellent thermal conductivity and strength while maintaining structural integrity in extreme conditions. In addition, Stainless Steel 446 is resistant to chloride stress corrosion and cracking, making it suitable for use in industrial furnaces, heat exchangers, and other complex applications where reliability is critical.
You’ll most commonly find Stainless Steel 446 hard at work in high-temperature settings. It is the material of choice for critical components like industrial furnace parts, heating element supports, and other thermal processing equipment. Its ability to withstand scaling and corrosion makes it invaluable in chemical plants and power generation facilities. It’s often specified for water softeners and heat exchangers, providing crucial performance where other metals might fail, making it a true workhorse in demanding industries.
