Description
(1) Low carbon steel Also known as mild steel, carbon content from 0.10% to 0.30% low carbon steel is easy to accept a variety of processing such as forging, welding and cutting, commonly used in the manufacture of chains, rivets, bolts, shafts and so on.
(2)Medium carbon steel Carbon steel with a carbon content of 0.25% to 0.60%. There are a variety of products such as killed steel, semi-killed steel, boiling steel. In addition to carbon, it may contain a small amount of manganese (0.70% to 1.20%).
(3) High carbon steel Often referred to as tool steel, carbon content from 0.60% to 1.70%, can be hardened and tempered. Hammers, crowbars,etc. are made of steel with a carbon content of 0.75%; cutting tools such as drill bits, wire taps, reamers, etc. are made of
steel with a carbon content of 0.90% to 1.00%.

Product Show
AISI 4130 steel bar is made of high-strength, low-alloy steel that is mainly used in high-temperature, high-pressure, and high-strength industrial fields. 4130 steel is a chromium-molybdenum low-alloy steel that has much higher strength and toughness than typical steel grades. Additionally, the reduced carbon content of this alloy, while limiting strength through thickness, provides better weldability than its 4140 steel counterpart. These properties make AISI 4130 steel bar a popular choice in the aerospace industry for manufacturing commercial and military aircraft components that require high strength and low weight.
