Directory of stainless steel grades

AISI 321 | EN 1.4541 | DIN X6CrNiTi18-10 - is an austenitic stainless steel which is able to provide excellent resistance to oxidation and corrosion. It has good creep resistance. It is used mainly in parts and structures involving continuous and intermittent working temperatures in the carbide precipitation range of 427 - 816 ℃. EN 1.4541 has the same corrosion properties as EN 1.4301 / AISI 304, except for improved resistance to intergranular corrosion due to the addition of titanium for stabilization. Resistance to organic acids and other acids is excellent. However, it should be noted that prolonged exposure to temperature can reduce the overall corrosion resistance, but this steel grade remains in a better condition compared to non-stabilized steel grades.

AISI 310S | EN 1.4845 | DIN X8CrNi25-21 | 20Х23Н18 - is a stainless steel that has high mechanical strength and impact toughness. It has excellent resistance to high-temperature oxidation due to the high content of chromium and nickel. And due to the low level of carbon, the release of carbides during welding or at high temperatures is reduced.

It should be noted that optimising steel for high temperatures means that its resistance to aqueous corrosion is limited.

AISI 444 | EN 1.4521 | DIN X2CrMoTi18-2 - is a low-carbon, molybdenum, titanium ferritic stainless steel. It has better corrosion resistance than conventional ferritic and austenitic stainless steels. It has good hardness properties and also has good resistance to sensitization during welding.

AISI 444 has very good corrosion resistance in many halogen-free organic and inorganic solutions over a wide range of temperatures and concentrations.

AISI 410 | EN 1.4006 | DIN X12CrN13 - is a general-purpose martensitic stainless steel. It contains 11.5% chromium, which provides good corrosion resistance. However, the corrosion resistance of steels can be further improved by a number of processes, such as hardening, tempering and polishing. Hardening and tempering make it possible to strengthen the steel. Typically, such stainless steels are used in areas involving moderate corrosion, heat resistance and high strength.

EN 1.4006 is sufficiently resistant to the effects of hot gases, steam, foodstuffs, weak acids and alkalis, fresh water and dry air.

AISI 202 | EN 1.4373 | DIN X12CrMnNiN18-9-5 is a widely used grade of stainless steel that is characterized by high hardness, strength and good corrosion resistance. It is quite well processed in annealed condition. For complete transformation and heat treatment, the material must be heated to a temperature of 1038 °C for 30 minutes and then cooled to below 16 °C.

AISI 204Cu | EN 1.4597 | DIN X8CrMnCuNB17-8-3 - is a special type of stainless steel that is a chromium-magnesium austenitic stainless steel. Due to the addition of copper, the steel has better formability than AISI 201 and AISI 304 stainless steels. Copper improves corrosion resistance and increases resistance to stress corrosion cracking in certain environments. EN 1.4597 is somewhere between the prices of 200 and 300 series stainless steels.
