Stainless Steel Grades Directory

AISI 203 | S20300 is one of the 200 series austenitic stainless steels containing a high percentage of chromium and nickel. The nickel and chromium content makes the alloy resistant to many chemicals, including chlorine, sulfuric and nitric acids. As a result, it is not affected by extreme temperatures and is often used in cryogenic systems.

AISI 422 | AISI 616 | EN 1.4935 | DIN X20CrMoWV12-1 is a high-alloy stainless steel with a martensitic crystal structure and good corrosion resistance. It is mainly used for parts exposed to high temperatures of up to 649 °C. With the right heat treatment, parts of this steel can also have excellent mechanical properties depending on the cross-section, shape and application.

Stainless steel grade AISI 429 | EN 1.4001 | DIN X7Cr14 is a ferritic steel. It is also known as chromium steel UNS S42900. This steel has good corrosion resistance and its weldability is better than that of AISI 430. In fact, it is a modified version of AISI 430 (AISI 429 has slightly lower chromium content than AISI 430).

AISI 430F | EN 1.4105 | DIN X6CrMoS17 | EN 1.4104 | DIN X14CrMoS17

AISI 430F | EN 1.4105 | DIN X6CrMoS17 and EN 1.4104 | DIN X14CrMoS17 are close in chemical composition and some properties to stainless steel grade AISI 430 (EN 1.4016). But there is a slight difference. The differences are in the addition of sulfur and molybdenum to their composition. Sulfur makes the chips easily breakable during processing. Sulfur is as dangerous as oil, so the processing process can be done very quickly using these grades of stainless steel. Since sulfur reduces the level of corrosion resistance, a small addition of molybdenum was added to this grade.

AISI 420F | EN 1.4029 | DIN X29CrS13 - is a martensitic alloy. The grade is identical to stainless steel AISI 420, but with the addition of sulfur to significantly improve machinability. This alloy has excellent corrosion properties when quenched and provides good ductility in the annealed condition.

AISI 414 | EN 1.4008 | DIN GX7CrNiMo12-1 is a martensitic stainless steel designed for primary forming of wrought products. It has moderately high tensile strength among wrought martensitic stainless steels. This alloy is actually an improved version of AISI 410. The addition of nickel to its composition resulted in a steel that is stronger than AISI 403 and AISI 410 at similar strength levels.
