SS 436 is a corrosion and heat resistant ferritic Chromium Steel. It can be polished to appear similar to Chromium plate. The material is magnetic in both annealed and cold rolled tempers. This grade of ferritic stainless steel has shown a greater resistance to ridging or roping defects as compared to type 430 stainless steel.
The alloy can be readily blanked and formed. The material can be resistance welded, brazed, and soldered. SS 436 is resistant to atmospheric corrosion and fresh water, but it not resistant to most salts and seawater. It is resistant to scaling by oxidation up to about 1400°F.
Available Sizes:
SS 436 is available from Hamilton Precision Metals as strip product in thicknesses from 0.001” to 0.050” (0.0254 mm to 1.27 mm) in widths up to 15.0” (381 mm). The material conforms to ASTM A240 and UNS S43600.
