420 Stainless Steel Round Bar Price Per kg

420 stainless steel is a high-carbon, martensitic stainless steel with excellent hardness and wear resistance. It is widely used in cutlery, surgical instruments, mechanical components, and industrial tools.
The price per kilogram of 420 stainless steel round bar depends on diameter, length, surface finish, and heat treatment. Understanding the specifications and advantages of 420 stainless steel is crucial for procurement professionals and engineers to make decisions that balance cost-effectiveness and performance.

 

420 Stainless Steel Round Bar Price per kg (Reference)

Hot Rolled 420 SS Round Bar	2.5 – 3.5

We use high-strength materials like wooden crates and steel straps to prevent damage during transport.

Each bar is wrapped in moisture-resistant materials to prevent corrosion during shipping.

Bars are packed according to the specific length and size requirements to ensure safe and efficient delivery.

Clear labeling and detailed documentation ensure easy identification and handling upon arrival.

 

Q1: Can 420 stainless steel round bar be quenched?
A: Yes. 420 stainless steel is martensitic and can be heat treated to a hardness of up to HRC 55, making it well-suited for wear-sensitive applications.
Q2: How does 420 stainless steel compare to 304 or 316 stainless steel?
A: 420 stainless steel offers greater hardness and wear resistance, but lower corrosion resistance than 304/316 stainless steel; it is best suited for cutting tools, blades, and industrial components, rather than harsh chemical environments.
Q3: Can 420 stainless steel be used in food processing?
A: Yes, provided the environment is not highly corrosive. For acidic or marine environments, 304 or 316 stainless steel is preferred.
Q4: What certifications are available?
A: Suppliers typically provide MTC (EN 10204 3.1/3.2), third-party inspection reports, heat treatment charts, and mill certificates.
