Precipitation hardening stainless steel
HuaNickel 1.4542 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 1.4542 is quite weldable. Its strength, corrosion resistance, and simplified manufacturing process can make HuaNickel 1.4542 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.

Austenitic stainless steelIn a strong oxidizing environment, the corrosion resistance of Type HuaNickel 1.4550 stainless steel is slightly improved compared to Type 1.4541 stainless steel. Type HuaNickel1.4550 is stable with a column and is more suitable for aqueous and cryogenic environments due to its good resistance to intergranular attack. Both HuaNickel1.4550 and 1.4541 are resistant to good polysulfuric acid stress corrosion cracking.

Ferritic stainless steelHuaNickel 1.4749 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. 1.4749 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 1.4749 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. HuaNickel 1.4749 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.

1.4833...
Heat-resistant stainless steelHuaNickel 1.4833is an austenitic heat-resistant alloy with an oxidation resistance of 1900°F at constant temperatures. When subjected to frequent thermal cycling, the alloy can resist about 1850°F. The high chromium content and relatively low nickel content of 309 provide a good high-temperature sulfur-containing atmosphere. 309 has only moderate resistance to carbon uptake and is not recommended for use in high carburizing environments. Usually in many product forms, the particle size and carbon content can meet the requirements of HuaNickel 1.4833 at the same time. Prolonged exposure to temperatures in the range of 1100-1600°F will result in the formation of some sigma, reducing ductility and impact resistance at room temperature.
