Stainless steels are widely used across industries due to their corrosion resistance, strength, and durability. Among the martensitic stainless steels, Stainless Steel 410 Plate holds a unique position. Known for its excellent mechanical properties and moderate corrosion resistance, SS 410 is extensively used in engineering, petrochemical, power generation, and other heavy-duty applications.
In this article, we provide an in-depth look at the properties, specifications, advantages, and applications of Stainless Steel 410 Plate.
Chemical Composition of Stainless Steel 410 Plate
Stainless Steel 410 is a martensitic grade alloy, primarily composed of chromium. Its typical composition is:
-
Chromium (Cr): 11.5–13.5%
-
Carbon (C): 0.08–0.15%
-
Manganese (Mn): up to 1%
-
Silicon (Si): up to 1%
-
Phosphorus (P): 0.04% max
-
Sulphur (S): 0.03% max
-
Iron (Fe): Balance
This composition ensures high strength and hardness after heat treatment, with moderate resistance to corrosion and oxidation.
Mechanical Properties
The Stainless Steel 410 Plate offers a balanced combination of toughness and strength. Typical properties include:
-
Tensile Strength: 485 MPa minimum
-
Yield Strength: 275 MPa minimum
-
Elongation: 20% minimum
-
Hardness: 170–207 HB
These properties make SS 410 ideal for components requiring wear resistance and durability under mechanical stress.
Key Features of Stainless Steel 410 Plate
-
Heat-Treatable: Unlike many stainless steels, SS 410 can be hardened through heat treatment.
-
Good Wear Resistance: Suitable for environments where mechanical wear and abrasion are common.
-
Moderate Corrosion Resistance: Performs well in mild atmospheres, fresh water, and some chemical environments.
-
Magnetic Properties: SS 410 remains magnetic in all conditions, making it useful in specialised applications.
-
Oxidation Resistance: Offers resistance to scaling at temperatures up to 650°C.
Standards and Specifications
Stainless Steel 410 Plate is manufactured to meet several international standards, including:
-
ASTM A240 / ASME SA240 – Standard for chromium and chromium-nickel stainless steel plates.
-
EN 1.4006 – European designation.
-
JIS SUS 410 – Japanese standard.
Plates are available in a wide range of thicknesses and dimensions, customised to industrial requirements.
Applications of Stainless Steel 410 Plate
The unique balance of mechanical strength and moderate corrosion resistance makes SS 410 Plate suitable for a wide range of applications:
1. Power Generation
