The main uses of stainless steel 316 are heat exchangers for pulp and paper-making equipment, dyeing equipment, film washing equipment, pipelines, and exterior materials for buildings in coastal areas. It is also used in the field of solenoid valves, mainly for housings, clamps, spheres, valve bodies, valve seats, nuts, valve stems, etc.

904L (N08904,, 14539) super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel, and 4.5% molybdenum. 904L stainless steel has good activation-passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, and has good corrosion resistance in neutral chloride-containing media. Very good resistance to pitting corrosion, as well as good resistance to crevice corrosion and stress corrosion. 904L stainless steel pipe is suitable for various concentrations of sulfuric acid below 70℃. It is resistant to acetic acid of any concentration and temperature under normal pressure, and the corrosion resistance in the mixed acid of formic acid and acetic acid is also very good.

Duplex stainless steel 2205 (UNS S31803) is the most widely used duplex alloy. Compared with all austenitic stainless steels such as type 316, 2205 has a higher chromium content, a lower nickel content and contains nitrogen. 2205 is a duplex stainless steel. Compared with 316L and 317L austenitic stainless steel, 2205 alloy is superior in resistance to pitting corrosion and crevice corrosion. It has high corrosion resistance. Compared with austenite, It has a lower coefficient of thermal expansion and higher thermal conductivity.

Stainless steel capillaries have good flexibility, corrosion resistance, high temperature resistance, abrasion resistance, tensile resistance, water resistance and provide excellent electromagnetic shielding performance. The stainless steel hose can be freely bent into various angles and curvature radii, and has the same flexibility and durability in all directions; the stainless steel hose has flexible pitches, good flexibility, and no blockage and stiffness. ; Between the side buckles of each section of the stainless steel threaded hose. It has a certain degree of tensile strength to prevent the damage of the hose from exposing the lines laid inside the hose, and the axial tension can withstand more than 6 times the nominal inner diameter.

310 stainless steel (UNS S31000) and its derivative grades not only have excellent high temperature performance, but also have good ductility and weldability. The carbon content of 310H (UNS S31009) is limited to the lower limit of the 310 carbon content range, which is a grade suitable for high-temperature applications. 310S (UNS S31008) is used when the application environment temperature range is lower than the so-called "high temperature" and there are moisture corrosives. Compared with 310H, the lower carbon content of 310S does reduce its high temperature strength.

17-4PH is a martensitic precipitation hardening stainless steel. The performance characteristic of 17-4PH is that it is easy to adjust the strength level, which can be adjusted by changing the heat treatment process. 17-4PH has good attenuation performance, strong resistance to corrosion fatigue and water droplets. Features: After heat treatment, the mechanical properties of the product are more perfect, and can reach a compressive strength of up to 1100-1300 Mpa (160-190 ksi). This grade cannot be used at temperatures higher than 300°C (572°F) or very low temperatures. It has good corrosion resistance to the atmosphere and diluted acids or salts.

316LN(1.4429 / UNS S31653) stainless steel is also called austenitic stainless steel. N is added to 316L steel to make it have the same characteristics as 316N. 316LN belongs to American standard austenitic stainless steel, the implementation standard: ASTM A276/A276M-17 316LN is a kind of low carbon nitrogen controlled austenitic stainless steel. Due to the addition of the N element, 316LN stainless steel has significantly improved its strength while retaining good plasticity and toughness. 316LN stainless steel is equivalent to 316N steel, but has excellent intergranular corrosion resistance.

XM-19 is an austenitic stainless steel. Its corrosion resistance and strength are unmatched by commercial materials at the same price. The corrosion resistance of Nitronic50 is better than 316, 316L, 317, 317L and other materials, and the room temperature yield strength is as high as twice that of these grades.

F65 in ASTM A694 is carbon steel forging, corresponding to domestic steel number Q345. The full name of A694 is ASTM A694, which is forgings for carbon steel and alloy steel pipe flanges, fittings, valves and parts for high-pressure transmission equipment. ASTM A694 grades are: F42, F46, F48, F50, F52, F56, F60, F65, F70.

F61 stainless steel is based on British alloy 255. It has good mechanical properties and local corrosion resistance, especially its wear resistance is better than ordinary austenitic steel, and it is an ideal material in seawater. According to the production process, F61 stainless steel can be divided into three types: hot rolled, forged and cold drawn. According to the ex-factory form, there are car light round, black leather round, and calendered rod.

F60 stainless steel is duplex steel 2205, also called S32205, commonly known as F60. F60 stainless steel corresponds to the China brand: 00Cr22Ni5Mo3N.
