420 Stainless Steel (SS 420): A Detailed Guide 

Introduction

If you’re here searching for anti-corrosive and hardened steel for your industrial plant, then you’re in the right place. Because Stainless Steel 420 is one of the most useful stainless-steel bars for better corrosion resistance, hard carbon materials and strong uses across industries.

Let’s know in detail about 420 Stainless Steel with this completed guide on SS 420. We have discussed what is 420 stainless steel, its properties, applications, benefits and how one of the leading Stainless Steel 420 manufacturers in India is making it.

420 Stainless Steel (SS 420)

SS 420 features a higher carbon content to improve hardness, strength, and wear resistance. It is a stainless steel with heavy carbon and low chromium. Like other stainless steels in the SS 400 series, SS 420 can be hardened through heat treatment.

Let’s know more about the features of stainless steel 420.

Features of SS 420

  • SS 420 offers strong resistance to corrosion and flexibility when annealed.
  • It has a hardness rating of 50HRC, making it the hardest among low-chromium stainless steels with a scaling temperature of around 650°C.
  • It is a martensitic stainless steel with high carbon levels for extreme hardness and is manufactured by hardening and tempering.
  • It can become soft and lose its ability to resist corrosion when it’s used at temperatures above 427°C.
  • It is widely utilized in cutlery, bushings, surgical and dental tools, scissors, and parts for pumps and valves, etc.
  • Properties of SS 420

    1. Chemical Composition

    We provide SS 420 grade stainless steel that has British Norm 1.4021, consisting of minimum 0.15% Carbon and maximum 1% Manganese, 1% Silicon, 0.040% Phosphorus, 0.030% Sulfur, and 12 to 14% Chromium.

    2. Grade Comparison

    As stainless steel 420 is martensitic steel, we have standard EURO 1.4021, that is JIS SUS 420 J1 grade.

    Applications of SS 420

    1. Surgical and Dental Tools

    Helpful for medical tools like scalpels and scissors, especially for dental tools.

    2. Cutlery

    Used to manufacture knives, razors, and cutters.

    3. Hand Tools

    Useful for hand tools like chisels and screwdrivers.

    4. Machine Components

    Used in pumps, shafts, and other machine components.

    5. Oil Industry

    Used for pump parts, valves, and pipes in the oil industry.

    Benefits of using Stainless Steel 420 Grade

    1. Hardness

    420 stainless steels have a higher carbon content that provides a greater degree of hardness after heat treatment.

    2. Wear Resilience

    It is extremely resistant to wear, especially when hardened, making it a good choice for tools, knives, and various machinery components.

    3. Polishing Ability

    It can be polished to a mirror-like finish, which can increase its aesthetic value and reduce friction.

    4. Corrosion Resistance

    It provides impressive corrosion resistance in mild atmospheric, domestic, and industrial environments. It's resistant to ammonia, blood, carbonic acid, crude oil, detergent liquids, dilute nitric acid, fresh water, food acids, many petroleum products, steam, and vinegar.

    5. Mechanical Features

    It also offers mechanical features similar to carbon steel in manufacturing tools with mechanical characteristics for industrial usage.
