SUS 309S...
Heat-resistant stainless steelHuaNickel SUS 309S is 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 SUS 309S 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.

Heat-resistant stainless steelat 2000°F, HuaNickel 310. Due to its high chromium and medium nickel content, HuaNickel 310 has good resistance to sulfurization and other forms of thermal corrosion. 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.

SUS 317L...
Austenitic stainless steelHuaNickel SUS 317L is a molybdenum-containing austenitic stainless steel with improved corrosion resistance over HuaNickel 304/304L and 316/316L stainless steels. The increased chromium, nickel and molybdenum content on 316L stainless steel improves chloride pitting and general corrosion. By controlling nitrogen addition, HuaNickel SUS 317L can generally meet the mechanical properties of 317 straight grade while maintaining low carbon content.

SUS 321...
Heat-resistant stainless steelHuaNickel SUS 321 stainless steel is a titanium stable grade that is typically used in the 1000-1600°F temperature range. For operating temperatures up to 1600°F, a stable treatment of 1550-1650°F, air cooling, can be used to provide optimal resistance to intergranular corrosion and polysulfuric acid stress corrosion cracking. HuaNickel SUS 321 stainless steel is easily welded by all common methods, including water arcing. The appropriate weld fillers are AWS ER347 bare wire and E347 overlay electrodes. The machinability of SUS 321 stainless steel is similar to that of 304 stainless steel. Compared to AISI B1112, it has a machinability rate of 45%.

SUS 347...
Austenitic stainless steelIn a strong oxidizing environment, the corrosion resistance of TypeHuaNickel SUS 347 stainless steel is slightly improved compared to Type 321 stainless steel. Type HuaNickel SUS 347 is stable with a column and is more suitable for aqueous and cryogenic environments due to its good resistance to intergranular attack. Both SUS 347 and 321 are resistant to good polysulfuric acid stress corrosion cracking.

SUS 420J2...
Martensitic stainless steelHuaNickel SUN 420 is a hardenable martensitic stainless steel with a similar chemical composition to 410, mainly due to the difference in carbon content. HuaNickel SUN 420 stainless steel has a lower carbon content than 410, which allows it to achieve higher strength and hardness at lower ductility. SUN 420 has corrosion resistance comparable to 410 and is typically used in applications that require high strength, high wear resistance, or good edge retention.

SUS 440C...
Martensitic stainless steelStainless steel HuaNickel SUS 440C is a high-carbon martensitic stainless steel. As a martensitic stainless steel, HuaNickel SUS 440C is magnetic and can be hardened by heat treatment. The high carbon content in HuaNickel SUS 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.

SUS 446...
Ferritic stainless steelSUS 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. SUS 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). HuaNickelSUS 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. SUS 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.

SUS 630...
Precipitation hardening stainless steelHuaNickel SUS 630 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 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.
