What are the main properties of 446 stainless steel plates?
446 stainless steel plates have excellent corrosion and oxidation resistance,
high-temperature strength, good formability, and weldability, and are suitable for
applications with extreme temperatures.
What are the maximum service temperatures for 446 stainless steel
plates?
The maximum service temperature for 446 stainless steel plates is around 950-1050°C
(1742-1922°F) in air and 760-870°C (1400-1600°F) in reducing environments containing
sulfur. At temperatures above these ranges, the strength and corrosion resistance of
446 stainless steel plates can be compromised.
How are 446 stainless steel plates fabricated?
446 stainless steel plates can be cut, formed, welded, machined, and finished using
various techniques. Due to its high chromium content, special tools and methods may
be required for machining. Sulfur-based cutting fluids should be avoided during
fabrication to maintain corrosion resistance.
What types of surface finishes are available for 446 stainless steel
plates?
446 stainless steel plates can be finished using different surface finishes,
including hot-rolled No. 1 finish, cold-rolled No. 2B and No. 2D finishes,
intermediate polished No. 3 finish, general purpose polished No. 4 finish, highly
reflective bright annealed finish, and various decorative finishes achieved through
etching, embossing, or other mechanical methods. The specific application and
aesthetic needs will determine the surface finish selection.
