Carbon Steel Bar
AISI 4130 carbon steel bar has excellent strength, toughness and processability. Through normalizing and quenching treatment, the steel can achieve high strength and strength. In addition, the bars have excellent weldability and forgeability.
Big fire special steel, high strength steel plate, steel industry supply and demand, steel suppliers
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.
