Special Bar Quality (SBQ) steel is a division of long steel products engineered for robust applications, such as bearings, crankshafts, gears, and drill-string components.


SBQ steel is known for its high strength, toughness, and fatigue resistance. It is manufactured using precise metallurgical practices and advanced manufacturing processes, which confirm the steel's reliability, efficiency, and performance. 


Aircraft quality steel is a type of steel that is used in the aerospace, defense, nuclear, private, and commercial industries. It is typically made from aluminum, alloy steel, stainless steel, and super alloys. 


The term "aircraft quality" is used to describe steel that meets the strict requirements of the aerospace industry. The steel is subjected to rigorous testing to ensure that it meets the required standards. The use of aircraft quality steel is essential in the aerospace industry as it ensures the safety and reliability of aircraft.


Bearing quality generally applies to alloy steel bars and tubes for anti-friction bearings. It is a type of steel that is used in the manufacturing of bearings, which are used in various functions such as automotive wheel hubs, transmission gears, and other machinery. The steel is known for its rolling fatigue strength and high wear resistance. 


Bearing quality steel is typically made from high-carbon chromium bearing steel, engineering steel, and some types of stainless steel and heat-resistant steel. The steel is subjected to demanding quality control measures to ensure that it meets the required standards. The use of bearing quality steel is essential in the manufacturing of bearings as it ensures the durability and reliability of the bearings.
