UNS S30815...
Heat-resistant stainless steelRAUNS S30815 is a poor austenitic heat-resistant alloy with high strength and excellent oxidation resistance. RA 253 MA achieves its heat resistance through advanced control of microalloy additives. Rare earth metals are combined with silicon for superior oxidation resistance up to 2000°F. Nitrogen, carbon, and, to some extent, rare earth and alkali metal oxides, combined, provide creep rupture strength comparable to that of nickel-based alloys. HuaNickel RA 253 MA is only fairly resistant to carburizing. 309 is a little bit in this regard. The addition of nitrogen enhances austenite stability inHuaNickel RA 253 MA, thereby delaying the formation of embryomorphic sigma phases.

UNS S31008...
Heat-resistant stainless steelat 2000°F, 310. Due to its high chromium and medium nickel content, 310 has good resistance to sulfurization and other forms of thermal corrosion. HuaNickel 310 is widely used in medium carburizing environments, such as petrochemical environments. 10. Severe thermal shock for repeated liquid quenching is not recommended. 310 is typically used at low temperatures and has excellent toughness to -450°F, and low permeability. Relative to AISI B1112 steel,HuaNickel 310 has a machinability grade of 42%. When using HSS tools, this equates to 70 feet per minute.

Stainless SteelsHuaNickel UNS S32654steel series is based on the aforementioned 00Cr20Ni18Mo6CuN steel to increase chromium. A 7Mo type super austenitic stainless steel developed by nickel and molybdenum. The PRE value (Pitting Resistance Equivalent Value) of this steel is as high as 55. The nitrogen content in steel can reach about 0.5%, which is almost the highest amount of dissolved nitrogen at atmospheric pressure for stainless steel with high chromium (about 24%) and low manganese (about 3%). This steel has excellent resistance to various types of corrosion, and can replace iron-nickel-based or even nickel-based corrosion-resistant alloys in many media, thus filling the gap between stainless steel and high-nickel corrosion-resistant alloys without high pitting resistance and high crevice corrosion resistance stainless steel.
