3Cr13...
Martensitic stainless steelHuaNickel 3Cr13 is a hardenable martensitic stainless steel with a similar chemical composition to 410, mainly due to the difference in carbon content. 420 stainless steel has a lower carbon content than 410, which allows it to achieve higher strength and hardness at lower ductility. 420 has corrosion resistance comparable to 410 and is typically used in applications that require high strength, high wear resistance, or good edge retention.

Martensitic stainless steelStainless steel HuaNickel 440C is a high-carbon martensitic stainless steel. As a martensitic stainless steel, HuaNickel 440C is magnetic and can be hardened by heat treatment. The high carbon content in 440C has high hardness and strength. Despite the high carbon content, the chromium content is still enough to maintain its stainless steel properties. Martensitic steels are typically used in applications that require high strength and moderate corrosion resistance.

466...
Ferritic stainless steelHuaNickel 446 is a high chromium ferrite heat-resistant alloy with excellent resistance to oxidation, vulcanization, and other forms of hot corrosion. This grade is most commonly used between 1500-2100°F, although it has a fairly low intensity at high temperatures. 446 is the only heat-resistant alloy that can withstand molten copper and brass. Like other high chromium ferritic stainless steels, in the temperature range of 700-1000°F (embrittlement at 885°F). HuaNickel 446 should not be used within this temperature range unless an almost complete loss of room temperature ductility can be tolerated. Sigma embrittlement occurs with prolonged exposure in the range of 1000-1300°F. 446 has a high toughness to brittle impact transition temperature. Therefore, successful forming and bending is contributing to low forming speeds, edge preparation and preheating to 250-400°F. Annealing, if necessary, should be performed at 1550-1650°F, followed by rapid cooling.

Precipitation hardening stainless steelHuaNickel17-4 stainless steel is an age-hardened martensitic stainless steel that combines high-strength and corrosion-resistant stainless steel. Hardening is done by a short, simple low-temperature treatment. Unlike traditional martensitic stainless steels, such as Type 410, Type 17-4 is quite weldable. Its strength, corrosion resistance, and simplified manufacturing process can make HuaNickel 17-4 stainless steel a cost-effective alternative to high-strength carbon steel and other stainless steel grades. At a solution treatment temperature of 1900°F, the metal is austenite, but transforms into a low-carbon martensitic structure during cooling to room temperature. This conversion will not be completed until the temperature drops to 90° Fahrenheit. It is then heated to 900-1150°F for 1 to 4 hours of precipitation to strengthen the alloy.

Precipitation hardening stainless steelHuaNickel 631 is an austenitic-martensitic precipitation hardened stainless steel developed on the basis of 18-8CrNi. It is also known as controlled phase change stainless steel.After solution treatment, it is an unstable austenite structure, with good plasticity and processability, after adjustment, the carbide phenology composition of austenite precipitation changes, and then after martensite transformation treatment, most of the structure is transformed into low-carbon tempered martensite with good toughness, which is the use state of steel and has good mechanical properties at medium temperature. The corrosion resistance is better than that of martensitic stainless steel.

Stainless SteelsHuaNickel 654SMO steel 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.
