Neil Metals stands out as a top manufacturer and supplier of Stainless Steel 420 Hollow Bars, proudly based in Kolkata, India. They’re recognized for delivering robust and high-strength stainless steel solutions that industries rely on for excellent wear resistance and moderate corrosion protection. The SS 420 hollow bars from Neil Metals find their way into various sectors, including automotive, engineering, medical, and industrial tooling, thanks to their impressive hardenability, machinability, and mechanical performance. With cutting-edge production capabilities and a strong commitment to quality, Neil Metals guarantees precise dimensions, timely deliveries, and compliance with international standards for both local and global clients.
Stainless Steel 420 Hollow Bars are martensitic stainless steel alloys that contain 12–14% chromium and 0.15–0.40% carbon, along with trace amounts of manganese, silicon, phosphorus, and sulfur. This unique blend allows the alloy to be hardened through heat treatment, resulting in exceptional strength and wear resistance. SS 420 boasts a tensile strength of up to 700–900 MPa and a yield strength of around 500 MPa, depending on how it’s tempered. Its moderate corrosion resistance, combined with the ability to maintain sharp edges and a polished finish, makes it perfect for precision machining and structural components.

SS 420 hollow bars' excellent wear resistance enhances their performance by ensuring durability in high-friction environments. This property makes them ideal for cutting tools, medical instruments, and mechanical components, reducing maintenance needs and extending service life in demanding applications.
SS 420 hollow bars offer moderate high-temperature resistance but are generally not ideal for prolonged exposure to extreme heat. Their performance is best in applications requiring hardness and corrosion resistance under controlled or moderately elevated temperature conditions.
These Stainless Steel 420 Hollow Bars are ideal for applications that demand high hardness, strength, and moderate corrosion resistance. They’re commonly used in pump shafts, surgical instruments, valve parts, bearings, and molds. The hollow design helps reduce weight while maintaining mechanical integrity, making them suitable for components in rotating machinery and fluid handling systems. SS 420 is also a go-to choice for automotive parts, industrial blades, and machine components where abrasion resistance is crucial. Its versatility in being heat-treated to various hardness levels allows it to cater to a wide range of industrial applications that involve wear, impact, and structural stress.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
