AISI 4140/4130/1020/1045 Steel Round Bar/Carbon Steel Round Bar/Alloy Steel Bars Price Per Kg

Sushang Steel Factory is a manufacturer specializing in the production of various types of steel products. AISI is an abbreviation for American Iron and Steel Institute and is used to represent the material grades and properties of different types of steel.

Here is some basic information about the several steel materials you mentioned: 4130 and AISI are alloy structural steels with good comprehensive mechanical properties. 4130 is usually used to manufacture gears, shafts and connecting rods that require high strength and high wear resistance, such as automotive parts or parts required in construction machinery. The strength and wear resistance of 4130 are higher than ordinary carbon steel, but it is easier to weld and deal with some brittle problems (such as cracks). 4130 steel round bar (AISI 625): usually refers to a heat-treated circular cross-section metal bar. It is mainly used in industries such as machining, construction and automobiles, for example, to make shaft components or fasteners such as bolts required for bearings or other structural parts.

1025. AISI is a carbon structural steel with good toughness, welding performance and good machining performance. It is often used in the manufacture of buildings, bridges and other large mechanical parts. 1025 steel round bar: This is a common carbon structural steel pipe, mainly used in the manufacture of automobiles, ships and other mechanical parts.

1045 AISI is a common carbon structural steel with good processability and weldability, and can be used to manufacture various structural and mechanical parts. 1045 steel round bar: This is a common carbon structural steel pipe, mainly used in the manufacture of automobiles, ships and buildings, especially parts that require high hardness and high strength.

Regarding the price issue you are concerned about: the price of steel will change according to changes in market supply and demand, steel raw material prices, production processes and other factors. The calculation of specific prices requires reference to real-time market quotations and relevant exchange rate data. If you want to know the specific steel price, please contact Sushang Steel Factory or check the relevant market quotation information for further confirmation and understanding of the actual situation.
