Stainless Steel Grades

Stainless steel contains at least 10.5% chromium, which makes it more functional in environments containing corrosive liquids and oxidation. However, this is not absolute. These alloys have two distinct properties in environments with liquids and vapors: they are “corrosion resistant” at temperatures below 650 ° C and “heat resistant” at higher temperatures.

300 Series Stainless Steel Alloys

Aluminum Alloys

Aluminum-base alloys have unique mechanical properties and they are corrosion resistance. These alloys are about one-third density of steel, nevertheless have higher strengths at the same weight ration. Their modulus of elasticity is one third of steel.

But with precision design, lighter and stronger properties can be cast with aluminum.

Copper-base alloys; Bronze & Brass

Copper-base alloys includes on main copper part mix with brass, bronze, copper and nickel. They are commonly used for marine and electric applications because of their high thermal conductivity, excellent corrosion resistance, ductility and toughness.

Carbon steel & Steel alloys

Carbon steel and low-alloy steels are the most widely used materials in the mechanical world. There is no other group of alloys that offer such a wide range of mechanical properties. Carbon steels are made of iron, carbon, manganese and silicon.

Low-alloy steels are similar to carbon steel but also have additional elements such as chromium and molybdenum to improve heat treatment process.

Nickel-base alloys

Nickel-base alloys contain nickel, chromium and molybdenum and are known for their high strength and resistance to heat and corrosion. They are also easily welded and formed.

Investment casting parts made from nickel alloys are commonly used in applications involving high temperatures or corrosive environments such as aerospace, marine and chemical industries.

Cobalt-base alloys

Cobalt-base alloys are highly resistant to corrosion and heat, which is due to the extraordinary properties of cobalt. These alloys contain large amounts of carbon, chromium and carbide components such as tungsten.

These alloys are very hard and retain their hardness at very high temperatures, which makes them difficult for machining. Investment casting is usually the most cost-effective way to make cobalt-base parts.

Tool Steels

There are a wide range of materials designed for cutting, punching and shaping other materials. Sanat Gostar makes tool steels with iron alloys containing 0.25 to 2.5% carbon and significant amounts of chromium, molybdenum, tungsten, vanadium, cobalt and smaller amounts of nickel.

These combination is used to give parts the desired hardenability, hardness, strength, And wear resistance.

Thermal Expansion Alloys

Alloys with controlled thermal expansion coefficient, such as Invar and Kovar, are produced on the basis of iron-nickel and are known for their low coefficient of thermal expansion (CTE).
