Introduction

The main purpose of stainless steel is for corrosion resistance as its corrosion resistance is due to chromium. Chromium oxide layer is formed when that oxide layer oxidizes by reacting it with oxygen. This reaction creates a passivation layer on the steel. The passivation layer protects the steel from oxidation and rust, and the chemical composition of stainless steel is the key factor in providing protection from corrosion.

Grades of Stainless Steel

Stainless steel is available in a variety of grades and is used in a variety of applications. Some of the more common types of stainless steel include martensitic, ferritic, and austenitic. One type of stainless steel that has been widely used is AISI 420/2Cr13.

AISI 420/2Cr13 Overview

AISI 420/2Cr13 is a martensitic stainless steel that is primarily used in tools and cutlery applications. This grade of stainless steel is normally hardened and tempered before use in the form of blades, knives, chisels, scissors, and razors.

Martensitic stainless steel is a hard, strong material with good corrosion resistance. It has high strength and hardness which makes it an excellent choice for tool and cutlery applications. It is often used in the medical and food processing industries.

AISI 420/2Cr13 Composition

AISI 420/2Cr13 is composed of a combination of nickel, molybdenum, and titanium with the following percentages:

• Chromium – 13.0–15.0%

• Carbon – 0.20–0.50%

• Nickel – 1.00–1.60%

• Molybdenum – 0.50–1.20%

• Titanium – 0.20–0.30%

• Manganese – 0.50–1.0%

• Silicon – 0.30–0.50%

• Phosphorus – 0.03–0.045%

• Sulfur – 0.025–0.040%

• Iron – balance

Physical Properties

AISI 420/2Cr13 has very good hardness and wear resistance, excellent corrosion resistance, and high tensile strength, making it a good choice for use in tools and cutlery.

The martensitic stainless steel has the following mechanical properties:

• Tensile strength: 590–810 MPa

• Yield strength: 315–495 MP

• Elongation: 5–15%

• Impact strength: 78–165 Joules

• Hardness: HRC 38–46

• Corrosion resistance: Excellent

• Heat treating: Annealing, tempering, and hardening

Applications

AISI 420/2Cr13 is a type of stainless steel that is used for a variety of applications. It is often used for the manufacture of cutlery and tools due to its hardness and wear resistance. Additionally, it is often used in the medical and food processing industries, as well as in industrial knives and blades.

Conclusion

AISI 420/2Cr13 is a martensitic stainless steel that is primarily used for making cutlery and tools due to its excellent hardness and wear resistance. It is highly resistant to corrosion and has very good mechanical properties such as tensile strength, yield strength, and hardness. Additionally, it is used in the medical and food processing industries, as well as in industrial knives and blades.
