436L Stainless Steel – Composition, Properties and Uses

436L Stainless Steel

Are you in the market for a stainless steel material that is resistant to corrosion and has great mechanical properties? If so, 436L stainless steel is an excellent option. Let’s look at this versatile alloy’s composition, physical and mechanical properties, and potential uses.

436L Stainless Steel Composition

Stainless Steel Grade 436L  is a ferritic grade of stainless steel with chemical elements that include iron, chromium, molybdenum, silicon, manganese, and carbon. This combination of elements makes it highly resistant to corrosion from chloride solutions and other substances. It also has good weldability, formability, and machinability.

Element Content (%)
Iron, Fe 80.49
Chromium, Cr 17.3
Molybdenum, Mo 1
Nickel, Ni 0.3
Manganese, Mn 0.3
Silicon, Si 0.3
Titanium, Ti 0.3
Carbon, C 0.01

436L Stainless Steel Physical Properties

436L ss has excellent ductility and toughness thanks to its low carbon content (less than 0.03%). It also boasts high strength (up to 1400 MPa) and good weldability and formability. Additionally, it has a relatively low coefficient of thermal expansion (11 μm/m/K).

436L Stainless Steel Mechanical Properties

Stainless steel 436L offers outstanding tensile strength (up to 760 MPa) and good fatigue resistance. Its hardness ranges from 200 HBW to 300 HBW, depending on the tempering temperature. It also features excellent corrosion resistance in oxidizing and reducing environments due to its high chromium content (>18%) and good oxidation resistance up to 870°C in air. This grade of stainless steel also exhibits excellent resistance to pitting corrosion in seawater applications due to its increased nickel content (>1%).
