Advanced Alloy Steel Solutions for Critical Applications
Samanar supplies premium alloy steel bars, sheets, and components engineered for enhanced strength, hardness, wear-resistance and durability — perfectly suited for demanding industrial sectors such as oil & gas, mining, heavy machinery, aerospace and infrastructure.
Alloy
About Product
“Alloy steel” refers to steel that has been alloyed with one or more additional elements (such as chromium, nickel, molybdenum, vanadium, manganese) to improve its mechanical and chemical properties. At Samanar, we offer a wide range of alloy steel products — including low-alloy and high-alloy grades — designed to meet exacting performance requirements in industries where standard carbon steel is insufficient.
Our alloy steel portfolio includes bars, sheets, plates, forgings, and profiles produced under strict metallurgical control. These materials deliver superior strength-to-weight ratio, improved toughness, enhanced wear and fatigue resistance, and stable behavior in elevated temperatures or corrosive conditions.
Whether your project involves heavy-duty shafts, high-stress gears, mining equipment, structural components in seismic zones, or specialized fasteners and fittings, Samanar’s alloy steel supply is engineered to deliver performance, reliability and global export readiness.
Types of Alloy Steel & Grades
Low-Alloy Steels
Designed for general engineering applications where improved properties are needed over carbon steel, but cost-efficiency remains important. Typical grades include 4140, 4340, 8620.
High-Alloy Steels
Feature higher percentages of alloying elements, delivering elevated performance in toughness, corrosion- and heat-resistance, fatigue life and dimensional stability.
Special Purpose Alloys
Nickel-chromium-molybdenum steels for heavy vehicles and critical shafts
Case-hardening steels for gears, pins, and high-wear components
Heat-resisting alloys for high-temperature environments
