Before introducing the classification of steel, briefly introduce the basic concepts of ferrous metals, steel and non-ferrous metals.
1. Black metal refers to an alloy of iron and iron. Such as steel, pig iron alloy, cast iron and so on. Both steel and pig iron are iron-based alloys with carbon as the main additive element, collectively referred to as iron-carbon alloys.
Pig iron is a product made by smelting iron ore into a blast furnace and is mainly used to make steel and make castings.
The cast pig iron is smelted in a molten iron furnace to obtain cast iron (liquid), and the liquid cast iron is cast into a cast iron, which is called cast iron.
The ferroalloy is an alloy composed of iron and silicon, manganese, chromium, titanium and other elements. The ferroalloy is one of the raw materials for steelmaking and is used as a deoxidizer and an alloying element additive for steel in steelmaking.
2. The steel used for steelmaking is put into a steelmaking furnace and smelted according to a certain process to obtain steel. Steel products include steel ingots, continuous cast slabs, and direct casting of various steel castings. Generally speaking, steel is generally referred to as steel rolled into various steel materials. Steel is ferrous but steel is not exactly equal to ferrous metal.
3, non-ferrous metals, also known as non-ferrous metals, refers to metals and alloys other than ferrous metals, such as copper, tin, lead, zinc, aluminum and brass, bronze, aluminum alloy and bearing alloys. In addition, chromium, nickel, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, etc. are also used industrially. These metals are mainly used as alloy additives to improve the properties of metals, among which tungsten, titanium, molybdenum, etc. are used to produce tools. Carbide. These non-ferrous metals are referred to as industrial metals, in addition to precious metals: platinum, gold, silver, and rare metals, including radioactive uranium, radium and so on.
Our factory produces all kinds of cold-drawn steel pipes and hot-rolled steel pipes, with annual inventory of more than 300 tons, standing specifications are 20x3--426x40 and other 20# 45# 16MN and other carbon steel and low-alloy seamless pipes, special materials Can be scheduled to produce, welcome new and old friends to visit and negotiate.
