Stainless Steel
Renowned for its corrosion resistance, stainless steel is a blend of steel with chromium and often nickel. It's widely used in kitchenware, medical instruments, and architectural structures. Its luster and resistance to staining and rust make it a popular choice for both functional and aesthetic applications.
Tool Steel
Characterized by its hardness and resistance to abrasion, tool steel is commonly used in cutting and drilling equipment. It often contains elements like tungsten, molybdenum, cobalt, and vanadium to enhance heat resistance and durability, making it ideal for tools and dies.
Carbon Steel Alloys
These alloys have higher carbon content than standard steel, improving hardness and strength. Used in high-strength applications like structural beams and automotive parts, carbon steel alloys are versatile but can be less ductile and more susceptible to corrosion.
Low Alloy Steel
Containing a smaller proportion of alloying elements (typically less than 5%), low alloy steel offers improved mechanical properties over standard carbon steel. It's used in pipelines, automotive components, and construction due to its enhanced strength and toughness.
High Alloy Steel
This type contains a higher percentage of alloying elements, giving it superior corrosion resistance and mechanical properties. It's used in aggressive environments like chemical processing plants and marine applications, where its durability and resistance to corrosive elements are essential.
Nickel Alloys
Steel blended with high nickel content exhibits excellent corrosion resistance and strength at high temperatures. Nickel alloys are particularly useful in extreme environments, such as jet engines, chemical plants, and oil rigs, due to their ability to withstand thermal and mechanical stress.
