317L Austenitic Stainless Steel is more resistant to chemical corrosion than conventional chromium-nickel austenitic stainless steel such as alloy 304. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is low carbon grade or L grade, which is resistant to sensitization during welding and heat treatment.

316LN Austenitic Stainless Steel.316LN is the addition of N to 316L steel to make it have the same characteristics as 316N. 316LN stainless steel is equivalent to 316N steel, but has excellent resistance to intergranular corrosion.

15-7PH Precipitation Hardened Stainless Steel.The hardness is higher after heat treatment. Better corrosion resistance. The precipitation hardening steel with copper added, and the steel developed with 2%-3% molybdenum instead of 2% chromium in 0Cr17Ni7Al steel, its basic performance is similar to 0Cr17Ni7Al steel, but the comprehensive performance is better than it. It can withstand various cold forming and welding processes in the austenitic state, and then obtain the highest strength after heat treatment

15-5PH Precipitation Hardened Stainless Steel Precipitation hardening stainless steel has high strength, high toughness, high corrosion resistance, high oxidation resistance and excellent formability, weldability and other comprehensive properties.

2507 Duplex Stainless Steel.2507 IS A FERRITIC AUSTENITIC (DUAL phase) STAINLESS steel WITH EXCELLENT RESISTANCE to point corrosion, CREvice corrosion and uniform corrosion.2507 is a ferritic austenitic (dual phase) stainless steel that combines many of the most beneficial properties of ferritic and austenitic steels. Due to the high chromium and molybdenum content of the steel, it has excellent resistance to point corrosion, crevices and uniform corrosion. The dual phase microstructure ensures that the steel has high resistance to stress corrosion rupture and high mechanical strength.

2205 Duplex Stainless Steel Molybdenum duplex stainless steel has good resistance to chloride stress corrosion under low stress. Generally, 18-8 austenitic stainless steel is prone to stress corrosion fracture in neutral chloride solution above 60°C. Heat exchangers and evaporators made of this kind of stainless steel in trace chloride and hydrogen sulfide industrial media have a tendency to produce stress corrosion fracture, while duplex stainless steel has good resistance.

904L Super Corrosion-Resistant Steel containing 14.0-18.0% chromium, 24.0-26.0% nickel, 4.5% molybdenum. 904L super austenitic stainless steel is a low carbon high nickel, molybdenum austenitic stainless steel, the introduction of France H·S company proprietary materials. It has good activation-passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, good pitting resistance in neutral chloride ion medium, and good resistance to crevice corrosion and stress corrosion. It is suitable for various concentrations of sulfuric acid below 70℃, resistant to any concentration and any temperature of acetic acid under atmospheric pressure, and corrosion resistance in the mixed acid of formic acid and acetic acid is also very good.

1.4529 Super Corrosion-Resistant Steel is very high resistance to pitting and crevice corrosion in halide medium and acidic environment containing sulfhydrine, can effectively resist chloride stress corrosion, also has good corrosion resistance in oxidizing and reducing medium, good stability, mechanical properties slightly better than 904L, can be used for -196 to 400℃ pressure vessel manufacturing.
