Common Stainless Steel Grades

Stainless steel 304/304L | 1.4301/1.4307 | X5CrNi18-10/X2CrNi18-9

SS304/304L is one of the most widely used austenitic stainless steel due to its excellent corrosion resistance and formability. 304L is a lower-carbon version of 304, offering better weldability.

Stainless Steel 316/316L | 1.4401/1.4404 | X2CrNiMo17-12-2

SS316 has similar mechanical properties to 304, with higher corrosion and chemical resistance. Ideal for marine applications. 316L, being a low-carbon version, offers better weldability.

Stainless Steel 303 | 1.4305 | X8CrNiS18-9

SS303 is specifically designed for excellent machinability while maintaining decent corrosion resistance. Its sulfur addition improves machinability, making it ideal for high-volume machining operations.

Stainless Steel 201 | 1.4372 | X7CrMnNi18-5

SS201 is austenitic stainless steel with low nickel content. It offers good strength, formability, and corrosion resistance but is less resistant to corrosion than 304 and 316 grades.

Stainless Steel 416 | 1.4005 | X12CrS13

SS416 is a martensitic grade with excellent machinability. It offers a good balance of corrosion resistance and strength, making it suitable for applications requiring precision and high wear resistance.

Stainless Steel 420 | 1.4021 | X20Cr12 | 20Cr13

SS420 is a martensitic alloy with high hardness and good wear resistance. It has moderate corrosion resistance and can be hardened to a high level through heat treatment.

Stainless Steel 430 | 1.4016 | X6Cr17

SS430 is a ferritic stainless steel with moderate corrosion resistance and good formability. It offers a cost-effective option for applications requiring good wear resistance and aesthetic appeal.

Stainless Steel 440C | 1.4125 | X105CrMo17

SS440C is a high-carbon martensitic grade known for its high hardness, excellent wear resistance, and corrosion resistance. After heat treatment, it can achieve hardness levels comparable to tool steels.

Stainless Steel 17-4 PH | 1.4542 | X5CrNiCuNb16-4

SS17-4 PH (Precipitation Hardening) is a versatile alloy offering excellent mechanical properties and good corrosion resistance. It can be hardened to 44 HRC through heat treatment, making it suitable for high-stress environments.

Stainless Steel 2205 Duplex | 1.4462 | X2CrNiMoN 22-5-3

SS2205 Duplex is a dual-phase steel combining austenitic and ferritic structures, which offers higher strength and excellent resistance to stress corrosion cracking, pitting, and crevice corrosion.

AISI 316

AISI 316 is an austenitic stainless steel alloy that provides superior corrosion resistance, especially in chloride environments. It is commonly used in marine, pharmaceutical, and food processing industries due to its resistance to rust and pitting.

EN 1.4581

EN 1.4581 is a high-alloy austenitic stainless steel that provides excellent resistance to corrosion and heat, particularly in aggressive environments like chemical processing. It is similar to AISI 316 but with slightly enhanced resistance to high temperatures.

CF3/CF3M

CF3 and CF3M are cast versions of stainless steel 304 and 316, respectively, with a lower carbon content. These grades are designed to provide better resistance to corrosion, especially in high-temperature environments.

CF8/CF8M

CF8 and CF8M are cast stainless steel grades equivalent to AISI 304 and 316, respectively. CF8M offers enhanced corrosion resistance, making it suitable for applications exposed to aggressive chemicals, seawater, and high temperatures.
