Alloy Steel Nuts are Nuts that are manufactured in various alloy types. Their chemical composition consists of elements such as chromium, vanadium. Also, tungsten and molybdenum are present in their chemical composition. The mentioned elements present in the chemical composition provide strength to them along with resistance towards corrosion. These are available in different types as well as grades.
Alloy 20 was mainly made to withstand environments bound with sulfuric acid. Its high amounts of nickel, chromium, molybdenum, and copper in its composition give outstanding resistance towards general corrosion. Alloy Steel B6 Nuts have properties such as durability. Alloy Steel B7 Nuts are used in oil and gas industries, chemical production, and so on. Alloy Steel B7M Nuts are made of carbon steel. The composition consists of zirconium, nickel, along with titanium and columbium content.
Alloy Steel B16 Nuts also have excellent properties such as high strength. The Alloy Steel 2 Nuts are manufactured from high-quality raw materials. Alloy Steel 2HM Nuts, like other Nuts, also undergo a series of tests to test and improve their quality. The Alloy Steel 2H Nuts are made for applications that are bound with unfavorable temperature ranges.
Alloy Steel GR 6 Nuts is an excellent combination of components such as chromium, manganese, carbon, silicon, and molybdenum. It also has phosphorus and sulfur. The Alloy Steel GR 7 Nuts have the characteristic of being durable. The Alloy Steel GR 7M Nuts also have various properties such as excellent strength and durability.
