This grade is a Cr-Ni Austenitic Steel (Titanium stabilized), which are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Stainless 304L has lower hot strength than 321 and so is not the best choice if the requirement is resistance to an operating environment over about 500°C. Applications are Aircraft exhaust manifolds, Expansion Joints, Furnace Parts, Heating element tubing and Heat Exchangers.

Stainless Steel Grade 440c

Uns S44004 (Ams 5618 / Ams 5630 / Ams 5580)

This grade is Cr hardenable Steel, which is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. With its High Carbon content, this grade is preferred for most Ball Bearing and Valve applications.

Stainless Steel Grade 403

Uns S40300 (Astm A276)

This grade is a Cr Steel hardenable by heat treatment, which has a lower strength due to the Carbon content and is a lower corrosion resistance grade. The Chromium levels are between 13-17%, which makes this material ideal for Turbine Applications, Missile Rocket components & Medical Instruments.

Stainless Steel Grade 410

Uns S41000 (Ams 5504 / Ams 5505)

This grade is a Cr steel hardenable by heat treatment, which will attain high mechanical properties after heat treatment. It has good impact strength, corrosion and scaling resistance up to 1200 F (649 C). Applications are steam and gas turbine blades and buckets, bushings, valve components, fasteners, screens and kitchen utensils.

Stainless Steel Grade 420

Uns S42000 (Ams 5506 / Ams 5621)

This grade is a Cr hardenable Steel, which is a higher Carbon version of Grade 410 with a minimum of 12 per cent Chromium, just sufficient to give corrosion resistance properties. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished. Common applications for this grade are Medical and Turbine instruments.

Stainless Steel Grade 422

Uns S42200 (Ams 5655)

This grade is Martensitic Cr Steel is a standard Martensitic, which is also known as plain chromium steel. Sometimes used in the annealed condition, 422 stainless steel bars achieve its best corrosion resistance when hardened then stress relieved. Applications are Gas Turbine, Steam Turbine, Oil and Gas compressor Parts.
