Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, focuses on premium **Stainless Steel 440C Bars and Rods**. These items are renowned for their exceptional hardness, resistance to wear, and capacity to endure corrosion. Engineered with accuracy to meet international standards, they deliver reliable performance even in the toughest industrial environments. Owing to their elevated carbon and chromium content, 440C stainless steel offers superb edge retention, mechanical strength, and durability. Al Summan Metals’ 440C Bars and Rods are ideal for uses that call for strong wear resistance, precision, and enduring reliability, making them well-suited for tooling, mechanical components, and high-performance machinery throughout industrial, marine, and engineering sectors.
Stainless Steel 440C Bars and Rods are made up of roughly 16–18% chromium and 0.95–1.2% carbon, together with small quantities of manganese, silicon, and molybdenum. This mixture yields great hardness, wear resistance, and reasonable corrosion resistance. They demonstrate remarkable mechanical characteristics, with a tensile strength between 760–1,000 MPa, hardness values that can climb to 58–60 HRC, and moderate ductility. Their martensitic structure adds outstanding fatigue resistance, toughness, and dimensional stability, which makes these bars and rods a great fit for high-stress, high-wear, and precision industrial uses that demand durability and reliability.

Stainless Steel 440C Bars and Rods are recognized for their exceptional hardness, reaching up to 58-60 HRC after heat treatment. This makes them well-suited for applications that demand outstanding wear and abrasion resistance.
Stainless Steel 440C provides adequate corrosion resistance in mild environments, but for harsher conditions (such as saltwater exposure), it is advisable to choose stainless steel grades with higher corrosion resistance like 316 or 317.
Al Summan Metals’ Stainless Steel 440C Bars and Rods are widely applied across industries where hardness, wear resistance, and corrosion protection matter most. They work perfectly for producing bearings, bushings, shafts, knives, cutting tools, and precision instruments. They also function in fasteners, mechanical assemblies, and wear-resistant parts subjected to friction and stress. Their distinctive blend of hardness, corrosion resistance, and dimensional stability ensures extended service life, dependability, and strong performance in demanding industrial, mechanical, and tooling applications.
We supply products accompanied by mill test certificates as well as third-party test certificates, guaranteeing the highest standards of quality and compliance.
Al Summan Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Dubai, UAE
