SS 430 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. The alloy can be readily blanked and formed. The material can be resistance welded, brazed, and soldered. SS 430 is resistant to atmospheric corrosion and fresh water, but it not resistant to most salts and sea water. It is resistant to scaling by oxidation up to about 1400°F. Available Sizes: SS 430 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 12.0” (304.8 mm). The material conforms to ASTM A240, FED QQS 766, and UNS S43000.

HPM® 455 is a precipitation heat treatable martensitic Stainless Steel. The composition provides a good combination of corrosion resistance and heat treated strength favorable for fatigue applications. The material is well suited for demanding spring devices The alloy has reasonably good forming characteristics in the annealed temper considering that it has a hardness of RC30. A significant radius is useful when bending is necessary in a fabrication. Cold working prior to the precipitation hardening treatment can drive finish strength up to 270,000 PSI (0.2% offset yield strength). The alloy retains a good strength through 800°F (Approx. 70% of room temperature). Resistance to stress – corrosion cracking is optimized by heat treating at 950°F. The overall corrosion resistant to normal atmospheric is equal to SS 430 with no staining. The alloy can be welded by resistance and inert gas shielded techniques. It also is suitable for brazing using a flux when possible.

Havar® is a heat treatable Cobalt base alloy that provides very high strength. The alloy has excellent corrosion resistance and is non-magnetic. Applications have included metal diaphragms for aerospace sensors, metal diaphragms for burst discs, power springs, gap spacers in magnetic heads, and target foils in nuclear physics. Forming cold rolled Havar requires large radius (90° Bend – 8 X thickness) prior to age hardening. The joining can be accomplished using both welding and soldering techniques.The ultimate endurance life is achieved by heat treating the alloy at 1000°F after 80% cold work. The alloy will retain 75% of room temperature strength up to 950°F (Figure 1). Available Sizes: Havar® is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.025” (0.0127 mm to 0.635 mm) and widths to 7.5” (190.5 mm). A foil product is available in thicknesses down to 0.000060” and widths of 4.0” (101.6 mm). The material corresponds to UNS R30004.

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.
