AISI 410 Durable Stainless Steel for Cutting Tools410 Stainless Steel

Product Overview

AISI 410 is a martensitic stainless steel renowned for its exceptional strength, moderate corrosion resistance, and excellent heat treatability. As a cost-effective option in the stainless steel family, it balances mechanical performance and affordability, making it a preferred choice across diverse industries.

This grade is recognized by multiple international standards, with key equivalents including EN X12Cr13/1.4006 (European), JIS SUS410 (Japanese), GB/T 1220 12Cr13/1Cr13 (Chinese), and GOST 5632-76 12X13 (Russian). Its versatility stems from its unique composition, primarily alloyed with 11.5-13.5% chromium—a key element enhancing its corrosion resistance and hardenability.

Features

Chemical Composition

The chemical makeup of AISI 410 and its equivalents is carefully balanced to deliver optimal performance:

Low carbon (≤0.15%) and controlled sulfur/phosphorus levels (≤0.030% and ≤0.040% respectively) ensure weldability and reduce brittleness, while high chromium content boosts resistance to oxidation and mild corrosive environments.

Mechanical Properties

AISI 410 exhibits impressive mechanical strength, especially after heat treatment:

· For JIS SUS410: Tensile strength of 540MPa min, yield strength of 345MPa min, elongation of 25% min, and impact value of 98J min at room temperature.

· For EN X12Cr13/1.4006 (quenched and tempered): Tensile strength of 650-850MPa, yield strength of 450MPa min, and elongation of 15% min.

These properties make it ideal for applications requiring both durability and ductility, such as load-bearing components and wear-resistant parts.

Supply and Tolerance

AISI 410 is available in various forms to suit industrial needs:

· Hot rolled bars: Diameter 10-130mm, length 5000-7000mm

· Hot forged bars: Diameter 140-600mm, length 2000-5800mm

· Hot rolled plates: Thickness 2-60mm, width 310-810mm, length 6000-12000mm

Tolerances vary by finish, with grinding/polished surfaces offering tight controls (+0/+0.05mm) for precision applications, while black forged/rolled options provide cost-effective solutions with +0/+5mm tolerance.

Heat Treatment

AISI 410 responds well to heat treatment, allowing customization of hardness and strength:

· Annealing: Heat to 800-900℃ (slow cooling) or 750℃ (quick cooling) for improved machinability.

· Quenching and tempering: Heat to 950-1000℃, oil-cool, then temper at 700-750℃ (quick cooling) to achieve optimal hardness (up to HBW 220) and toughness.

Applications

Cutting Tools and Instruments

· Table knives, surgical blades, and razor blades (benefit from high hardness post-heat treatment).

· Industrial cutting tools and mold parts (resist wear under repeated use).

Machinery and Automotive Components

· Pump shafts, valve parts, and fasteners (bolts, nuts) (withstand mechanical stress and mild corrosion).

· Turbine blades and bearing collars (tolerate high rotational forces).

· Automotive exhaust system parts (resist high-temperature oxidation).

Petroleum and Chemical Equipment

· Valves, flanges, and pipe fittings (perform in weakly corrosive environments like mild acids).

· Oil drilling components (e.g., drill bits, bushings) (endure harsh operational conditions).

Structural and Wear-Resistant Parts

· Mining machinery wear parts (resist abrasion from rocks and debris).

· Gears and shafts (heat-treated for enhanced surface hardness).

FAQ

What makes AISI 410 different from austenitic stainless steels like 304?

AISI 410 is martensitic (magnetic, heat-treatable for high strength), while 304 is austenitic (non-magnetic, better corrosion resistance but lower strength). It’s more affordable than 304, making it ideal for strength-focused applications.

How corrosion-resistant is AISI 410?

It offers moderate corrosion resistance, suitable for dry or mildly humid environments. It may rust in highly salty or acidic conditions, so it’s not recommended for marine or chemical processing with strong acids.

Can AISI 410 be welded?

Yes, but with caution. Welding can reduce corrosion resistance, so post-weld annealing is advised to restore properties.

What is the maximum operating temperature for AISI 410?

It performs well up to 600℃ in oxidizing environments, making it suitable for high-temperature applications like exhaust components.
